Which statements describe one of the transformations performed on f(x) =^2 to create g(x) = -(x - 2)^2+5 ?

Answer:

y=2x+3

Step-by-step explanation:

Hi there!

We want to write the equation of the line

We are given that the y-intercept of the line is (0,3) and that the line also goes through the point (2,7)
There are many ways to write the equation of the line, but the most common way is slope-intercept form, which is given as y=mx+b, where m is the slope and b is the y intercept

The value of b is actually the value of y in the point making point of the y intercept
In this case, that point would be 3

So the value of b in this case is 3

Substitute 3 as b into the equation:
y=mx+3

Now we need to find m

As the equation passes through the point (2,7), we can use it to help solve for the value of m

Substitute 2 as x and 7 as y into the equation:

7=2m+3

Subtract 3 from both sides

4=2m

Divide both sides by 2

m=2

Substitute 2 as m into the equation:

y=2x+3

Hope this helps!

[tex]f(x)=-(x+8)(x-2)[/tex]

Step-by-step explanation:

Start by factoring out a -1...

[tex]f(x)=-(x^2+6x-16)[/tex]

Now, we have to find two integers that multiply to get -16 and have a sum of 6:

(-2)*8=-16

-2+8=8-2=6

Using this, we can split 6x into -2x and 8x...

[tex]f(x)=-(x^2-2x+8x+16)[/tex]

Factor  the first and second half separately...

[tex]f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\[/tex]

Since both x and 8 are being multiplied by x-2, we can combine them to get...

[tex]f(x)=-(x+8)(x-2)[/tex]

Answer:

(-2,6)

Step-by-step explanation:

Since both of the equations are equal to y, we can set these equations equal to each other. This means that the new equation using substitution is -8x-10=-6x-6.

-8x=-6x+4

-2x=4

x=-2

This means that the x value is -2. Then, to find the y value, substitute -2 into the first equation (the second equation also works if you want to). So, the equation looks like y=-8(-2)-10. Solve this and it gives you y=6. Therefore, the final coordinate pair is (-2,6).

Answer:

a = 117°

Step-by-step explanation:

The exterior angle of a triangle = the sum of the remote interior angles.

a + 25° = (a - 47°) + (a - 45°)

a + 25° =  (a + a) + (-47 - 45)

a + 25° = 2a - 92°

-2a        =  -2a        

-a  +25   =    -92

      -25  =     -25    

-a            =  -117°

a = 117°

Step-by-step explanation:

Answer:

[tex]y - 6 = 5[/tex]

equation are màthematical statements containing two algebraic expression on both sides of an "equal to (=)" sign.

Answer:

the answer is C/3

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    v/5-4-(v/4)=0

                 v

Simplify   —

                 4

  v          v

 (— -  4) -  —  = 0

  5          4

STEP 2:

                v

Simplify   —

                 5

Equation at the end of step

2

:

  v          v

 (— -  4) -  —  = 0

  5          4

STEP 3:

Rewriting the whole as an Equivalent Fraction

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

        4     4 • 5

   4 =  —  =  —————

        1       5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

3.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

v - (4 • 5)     v - 20

———————————  =  ——————

     5            5  

Equation at the end of step 3:

 (v - 20)    v

 ———————— -  —  = 0

    5        4

STEP 4:

Calculating the Least Common Multiple :

4.1    Find the Least Common Multiple

     The left denominator is :       5

     The right denominator is :       4

       Number of times each prime factor

       appears in the factorization of:

Prime

Factor   Left

Denominator   Right

Denominator   L.C.M = Max

{Left,Right}

5 1 0 1

2 0 2 2

Product of all

Prime Factors  5 4 20

     Least Common Multiple:

     20

Calculating Multipliers :

4.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 4

  Right_M = L.C.M / R_Deno = 5

Making Equivalent Fractions :

4.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      (v-20) • 4

  ——————————————————  =   ——————————

        L.C.M                 20    

  R. Mult. • R. Num.      v • 5

  ——————————————————  =   —————

        L.C.M              20  

Adding fractions that have a common denominator :

4.4       Adding up the two equivalent fractions

(v-20) • 4 - (v • 5)     -v - 80

————————————————————  =  ———————

         20                20  

STEP 5:

Pulling out like terms :

5.1     Pull out like factors :

  -v - 80  =   -1 • (v + 80)

Equation at the end of step 5:

 -v - 80

 ———————  = 0

   20  

STEP 6:

When a fraction equals zero :

6.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 -v-80

 ————— • 20 = 0 • 20

  20  

Now, on the left hand side, the  20  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -v-80  = 0

Solving a Single Variable Equation:

6.2      Solve  :    -v-80 = 0

Add  80  to both sides of the equation :

                     -v = 80

Multiply both sides of the equation by (-1) :  v = -80

The total cost of canvas required to make the tent at the rate of Rs. 15 per square meter is; Rs. 24,997

We are told that the bottom part of the tent house is a square cuboid up to a height of 10 m.

Thereafter, it is a pyramid.

Now, formula for volume of a cuboid is;

V = lwh

V = 20 * 20 * 10

V = 4000 m³

Formula for volume of a pyramid is;

V = lwh/3

V = (20 * 20 * h)/3

V = 400h/3

Total volume is 4800 of the entire tent house. Thus;

4000 + (400h/3) = 4800

400h/3 = 800

h = (800 * 3)/400

h = 6 m

Now, from online calculation, the surface area of the pyramid excluding the base is;

TSA_p = 466.48 m²

Total surface area of cuboid excluding the top is;

S.A = 1200 m²

Total surface area of canvas = 1200 + 466.48 = 1666.48 m²

Since cost per sq.m is Rs. 15 per m², then;

Total cost = 15 * 1666.48

Total Cost = Rs. 24,997

Empirical rule is defined for normal distributions. The percentage of the parts the lengths between 3.8 inches and 4.2 inches lie is: Option B: 68%

According to the empirical rule, also known as 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95% and 99.7% of the values lies within one, two or three standard deviations of the mean of the distribution.

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma) = 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma) = 99.7\%[/tex]

where we had  

[tex]X \sim N(\mu, \sigma)[/tex]

where mean of distribution of X is [tex]\mu[/tex] and standard deviation from mean of distribution of X is [tex]\sigma[/tex]

For the given case, as it is given that the lengths of a lawn mower part are approximately normally distributed, let its lengths be tracked by a random variable X

Then, [tex]X \sim N(\mu =4, \sigma = 0.2)[/tex]

The needed percentage is

[tex]P(3.8 < X < 4.2)[/tex]

We can rewrite it as:

[tex]P(4-0.2 < X < 4 + 0.2)[/tex]

This is the percent of values lying under one standard deviation about the mean of X. Using the empirical rule, we get the percentage as:

[tex]P(\mu - \sigma < X < \mu + \sigma) = 68\%[/tex]

Thus,

[tex]P(4-0.2 < X < 4 + 0.2) = 68\%[/tex]

Thus, The percentage of the parts the lengths between 3.8 inches and 4.2 inches lie is: Option B: 68%

Answer:

  a = -2/9

Step-by-step explanation:

Locate two points that cross grid intersections and compute the slope of the line between them. I would choose the vertex (4, 4) and the point (-5, 2) as being points where the graph crosses grid intersections.

The slope of the line between those points is given by the slope formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (2 -4)/(-5 -4) = -2/-9 = 2/9

We note that this representation of the absolute value function appears inverted (reflected across the x-axis). That means the coefficient 'a' will be negative. The slope of an unmodified absolute value function is -1 to the left of the vertex. It will only be 2/9 if the function has been multiplied by -2/9.

  a = -2/9

Additional comment

The vertex on the graph is at (4, 4), so the values of (h, k) are (4, 4).

Answer:

[tex]-\frac{2}{9}[/tex]

Step-by-step explanation:

Using the points (-5,2) and (4,4), the slope is given as 2/9. This is an absolute value graph, so from this information the slope is either 2/9 or -2/9. The graph faces downwards, so the slope is negative and therefore [tex]-\frac{2}{9}[/tex].

Answer:

[tex]y=e^x+3[/tex]

Step-by-step explanation:

By inspection, we can see that the curve crosses the y-axis at (0, 4)

Therefore, when x = 0, y = 4

Inputting x = 0 into the equations:

[tex]y=e^{x-3} \implies y=e^{-3}[/tex]

[tex]y=e^x+3 \implies y=e^0+3=1+3=4[/tex]

[tex]y=e^{x+3} \implies y=e^4[/tex]

[tex]y=e^{x-3}+3^3=e^{-3}+27[/tex]

Therefore, the only equation that gives y = 4 when x = 0 is [tex]y=e^x+3[/tex]

Check option B

[tex]\\ \rm\longmapsto y=e^x+3[/tex]

Put values

[tex]\\ \rm\longmapsto y=e^0+3=1+3=4[/tex]
