The value of x will be;

⇒ x = 13.9

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle is shown in figure.

Now,

Since, We know that;

The sine rule is;

⇒ sin A / a = sin B / b = sin C / c

By given figure, we get;

⇒ sin 83°  / x = sin 68° / 13

⇒ sin 83° × 13 / sin 68° = x

⇒ x = 0.99 × 13 / 0.92

⇒ x = 13.9

Answer: 10 is the range, option B/ option G

Step-by-step explanation: range is the most subtracted by the least, so organize the data set which makes it (5, 7, 10, 11, 12, 13, 15, 15, 15)

15 - 5 is 10.

Domain F(x) = All real numbers and the Range F(x)  [ -2 ,  + ∞ ]

A domain is the set of values for which the given function is defined.

Range is the set of all values which the given function can output.

The curve points are

P₁ ( -1,5 , 0 )   Q ( 0. -2 ) and P₂ ( 1,5 , 0 )

We can see that P₁  and P₂ are symmetric around the y-axis, and point Q looks like a vertex so we can conclude the curve as

ax² + bx + c = y

The curve is a parabola

when x = 0      

y = -2    

then   c  = - 2

The equations we get,

a (-1.5)²  +  b (-1.5) + c = 0      

2.25a  - 1.5b - 2 = 0

a (1.5)²   +  b ( 1.5)  + c = 0    

2.25a + 1.5b -2 = 0

Adding these two equations

4.5a - 4 = 0

a =  4/4.5

The vertex is Q ( 0 , -2 )

x = - b/2a      

0 = - b/ 9      

b  =  0

Therefore the equation of the function :

ax² + c = 0

(4/4.5) x² - 2 = 0

Therefore, Domain F(x) = All real numbers and the Range F(x)  [ -2 ,  + ∞ ]

Step-by-step explanation:

The approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

(a) t = 10 days and a day earlier

This means that:

t = 10 and t = 9

The function is given as:

[tex]N(t) = 100000e^{\frac{-(t - 10)^2}{8}}[/tex]

Calculate N(10)

[tex]N(10) = 100000e^{\frac{-(10 - 10)^2}{8}}[/tex]

Evaluate

N(10) = 100000

Next, calculate N(9)

[tex]N(9) = 100000e^{\frac{-(9 - 10)^2}{8}}[/tex]

Evaluate

N(9) = 88249.6902585

The slope is then calculated using"

[tex]m = \frac{N(10) - N(9)}{10 - 9}[/tex]

This gives

[tex]m = \frac{100000 - 88249.6902585}{10 - 9}[/tex]

Evaluate

m = 11750.3097415

Approximate

m = 11750

(b) t = 10 days and a day later

This means that:

t = 10 and t = 100

The function is given as:

[tex]N(t) = 100000e^{\frac{-(t - 10)^2}{8}}[/tex]

In (a), we have:

N(10) = 100000

Next, calculate N(11)

[tex]N(9) = 100000e^{\frac{-(11 - 10)^2}{8}}[/tex]

Evaluate

N(11) = 88249.6902585

The slope is then calculated using:

[tex]m = \frac{N(11) - N(10)}{11 - 10}[/tex]

This gives

[tex]m = \frac{88249.6902585 - 100000}{11 - 10}[/tex]

Evaluate

m = -11750.3097415

Approximate

m = -11750

Hence, the approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

Answer:

3/7  /    42.8% chance

Step-by-step explanation:

There are 6 striped balls (9, 10, 11, 12, 13, 14) and 8 (1, 2, 3, 4, 5, 6, 7, 8) solid colored balls. So, 6 / 14 balls are striped.

(6 / 14  = 3 / 7)

this means that the probability of a ball being striped has the odds of 3/7

(3/7 = about 42.8% chance)

Answer:

B

Step-by-step explanation:

Answer:

1.) ∞

2.) -∞

3.) 0

4.) 0

Step-by-step explanation:

As you approach x = -2 from the left, the "y" values are going to infinity. You never actually get a "y" value that equals x = -2 because of the vertical asymptote.

As you approach x = -2 from the right, the "y" values are going to -infinity. You never actually get a "y" value because there is a vertical asymptote.

As you approach x = 2, both sides converge to y = 0. At this point, there is a smooth, uninterrupted line.

The actual "y" value at x = 2 is 0 because the function goes straight through this point. So, you can just read this point as usual.

Paulo and Jason wear smaller shoe sizes than Carmen.

Jason and Carmen scored more runs than Paulo.

Step-by-step explanation:

Answer:

10 cm

Step-by-step explanation:

See attached image

Answer:

length = 10 cm

Step-by-step explanation:

Fyi, breadth is a synonym to width.

Since P=30, we must find the length.
l = length
w = width
P=w+w+l+l

30 = 5+5+l+l
30 = 10+2l
-2l = -20
l = 10

Hence, the length is 10 cm.

Answer:

a) 15/8   b) 25/18

Step-by-step explanation:

a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator:  [tex]\frac{5+4+6}{8} =\frac{15}{8}[/tex]

Since this can not be simplified any further, your final answer is 15/8.

b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same: [tex]\frac{12+3+10}{18} = \frac{25}{18}[/tex]

Since this cannot be simplified further either, your final answer is 25/18.

Hope this helps! :)

Answer:

so to add we need to find lcm

Step-by-step explanation:

a) 5/8 + 1/2+3/4                            lcm of 2,4 and 8 = 8

5/8 = 5/8

1x4
2x4  =  = 4/8

3x2
4x2    = 6/8

5/8 + 4/8 + 6/8 = 15/8


b) 2/3 + 1/6 + 5/9                       lcm of 3 , 6 and 9 = 18

2x6
3x6  = 12/18

1x3
6x3      = 3/18

5x2
9x2 = 10/18

12/18 + 3/18 + 10/18 = 25/18

compound interest is just an exponential sequence really, where the next value is some exponential amount of the previous.

hmmm that can happen in say, a bouncing ball, the 1st bounce is high, let it keep on boucing by itself and the next bounce is usually a compounded value of the previous one, since it's smaller it'd be a Decay type of equation.

2. Sin(∠mA)   = [tex]\dfrac{\sqrt{20}}{\sqrt{35}}[/tex]

3. Tan(∠mB)  =  [tex]\dfrac{b}{a}[/tex]

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

The angles will be calculated by using trigonometric identities.

1. For the first triangle:-

Cos∠mA = [tex]\rm \dfrac{Base}{Hypotenuse}[/tex]

We can see in the first triangle base is 3 and the hypotenuse is 5.

Cos∠mA =  [tex]\dfrac{3}{5}[/tex]

2. For the second triangle:-

Sin∠mA = [tex]\rm \dfrac{Perpendicualr }{Hypotenuse}[/tex]

We can see in the first triangle Perpendicular is √20 and the hypotenuse is √35.

Sin∠mA =  [tex]\dfrac{\sqrt{20}}{\sqrt{35}}[/tex]

3. For the third triangle:-

Tan∠mB = [tex]\rm \dfrac{Perpendicualr }{Base}[/tex]

We can see in the first triangle Perpendicular is b and the Base is a.

Tan∠mA =  [tex]\dfrac{b}{a}[/tex]

There is 1 square at each end.

There are 2 congruent trapezoids in the middle

Draw a 7 inch line across the widest part of the middle

Area of the squares

Area = s^2

s = 3

Area = 3^2

Area = 9

But there are 2 of them                                        18

Area of the 2 trapezoids

Area = (b1 + b2)*h / 2

b1 = 3

b2 = 7    Notice that 7 was the line you drew

h = 5

Area = (3 + 7)*5/2

Area = 50 / 2

Area = 25

Total Area                                                              68
