Answer:

c = [tex]\sqrt{90}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse c is equal to the sum of the squares on the other 2 sides, that is

c² = 9² + 3² = 81 + 9 = 90 ( take the square root of both sides )

c = [tex]\sqrt{90}[/tex]

Answer:

3 Ohms

Step-by-step explanation:

U1 = 5 ohm × 1.5 amps = 7.5 V

U2 = U - U1 = 12 - 7.5 = 4.5 V

R2 = U2 / I = 4.5 / 1.5 = 3 Ohms

use rise over run! this means  "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).

Step-by-step explanation:

Answer:

[tex]y = 120 + 0.15x[/tex]

Step-by-step explanation:

Given

[tex]Additional\ Fee = \$0.15[/tex] per vertical meter

[tex]y = fee[/tex] per x meter

[tex]x = vertical\ meter[/tex]

For:

[tex]x = 3500[/tex] --- [tex]y = 645[/tex]

Required

Determine the equation that relates y to x

Let the initial fee be represented with m

The equation that relates y to x is:

[tex]y = Initial\ Fee + Additional\ Fee * Vertical\ Meter[/tex]

This gives

[tex]y = m + 0.15 * x[/tex]

We need to first solve for m

From the question,

[tex]x = 3500[/tex] when [tex]y = 645[/tex]

So:

[tex]645 = m + 0.15 * 3500[/tex]

[tex]645 = m + 525[/tex]

Make m the subject

[tex]m = 645 - 525[/tex]

[tex]m = 120[/tex]

So, the initial fee is $120

Substitute 120 for m in [tex]y = m + 0.15 * x[/tex]

[tex]y = 120 + 0.15 * x[/tex]

[tex]y = 120 + 0.15x[/tex]

Hence, the required equation is: [tex]y = 120 + 0.15x[/tex]

Answer:

The longest day of the year is day 172  

Step-by-step explanation:

Since the length of day is L(t)=727+22sin[2π(t−80.75)/365], the maximum length of day is obtained when sin[2π(t−80.75)/365] is at its maximum value which is 1. So. sin[2π(t−80.75)/365] = 1

We now solve this to find the day at which this maximum value occurs.

sin[2π(t−80.75)/365] = 1

[2π(t−80.75)/365] = sin⁻¹(1)

[2π(t−80.75)/365] = π/2

dividing both sides by 2π/365, we have

[2π(t−80.75)/365] ÷ 2π/365 = π/2 ÷ 2π/365

t−80.75 = 365/4

t−80.75 = 91.25

t = 91.25 + 80.75

t = 172

The longest day of the year is day 172

  f(x) = -1/4(x +3)² -2

Step-by-step explanation:

The graph is shifted left 3 and down 2. It is also reflected over the x-axis and vertically compressed. The leading coefficient will be a negative fraction, and the offsets will replace x with x+3, and will add -2 to the scaled function.

Hello!

[tex]\large\boxed{x^{4}}[/tex]

Recall that:

[tex]\sqrt[z]{x^{y} }[/tex] is equal to [tex]x^{\frac{y}{z} }[/tex].  Therefore:

[tex]\sqrt[3]{x^{2} } = x^{\frac{2}{3} }[/tex]

There is also an exponent of '6' outside. According to exponential properties, when an exponent is within an exponent, you multiply them together. Therefore:

[tex](x^{\frac{2}{3} })^{6} = x^{\frac{2}{3}* 6 } = x^{\frac{12}{3} } = x^{4}[/tex]

Answer:

a) 31.4 cm b) 22.0 cm c) 9.4 mm d) 18.8 m e) 1.6 m f) 28.3 cm g) 78.5 cm h) 9.7 m

Step-by-step explanation:

All it really is multiply the diameter which is the straight line through the center of the circle

C = d × \pi

The circumference of the circles is A. 31.4 cm, B. 22cm approx,

C. 9.4 mm, D. 18.88 m, E. 1.6 m, F. 28.3 cm, G. 78.5 cm, H. 4.1 m.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.

Given circles,

circumference  of circle is 2πr in form of diameter = πd

where d is diameter,

A. given d = 10 cm

circumference   = c = πd

c = 3.14 x 10

c = 31.4 cm

B. given, d = 7 cm

c= πd

c = 3.14 x 7

c = 21.98 cm = 22 cm approx

C.given, d= 3 mm

c = πd

c = 3.14 x 3

c = 9.4 mm

D. given d = 6 m

c = πd

c = 3.14 x 6

c = 18.8 m

E. given c = 0.5 m

c = πd

c = 3.14 x 0.5

c = 1.6 m

F. given d = 9 cm

c = πd

c = 3.14 x 9

c = 28.3 cm

G. given d = 25 cm

c = πd

c = 3.14 x 25

c = 78.5 cm

H. given d = 1.3 m

c = πd

c = 3.14 x 1.3

c = 4.1 m

Hence the circumference is as follows.

Answer:

The option D represents an interval with a positive average rate of change.

Step-by-step explanation:

Let [tex]f(x) = x^{2}+10[/tex], the average rate of change on the interval [tex][a,b][/tex] is represented by the definition of the secant line:

[tex]\bar f = \frac{f(b) -f(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds, dimensionless.

[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds, dimensionless.

Now we proceed to check each option:

A. [tex]a = -3[/tex], [tex]b = 3[/tex]

[tex]\bar f = \frac{19-19}{3-(-3)}[/tex]

[tex]\bar f = 0[/tex]

B. [tex]a = -4[/tex], [tex]b = -1[/tex]

[tex]\bar f = \frac{11-26}{(-1)-(-4)}[/tex]

[tex]\bar f = -5[/tex]

C. [tex]a = -3[/tex], [tex]b = 1[/tex]

[tex]\bar f = \frac{11-19}{1-(-3)}[/tex]

[tex]\bar f = -2[/tex]

D. [tex]a = -1[/tex]. [tex]b = 2[/tex]

[tex]\bar f = \frac{14-11}{2-(-1)}[/tex]

[tex]\bar f = 1[/tex]

The option D represents an interval with a positive average rate of change.

Step-by-step explanation:

Answer:

always true

Step-by-step explanation:

Distribute the left side

2(x + 3) = 2x + 6

Simplify the right side

5x + 6 - 3x ← collect like terms

= 2x + 6

Thus

left side = right side , so always true

Equation 2(x + 3) = 5x + 6 - 3x is an identity which is always true.

An identity is an equation which is always true, no matter what values are substituted.

Identities can be written with the sign ≡.

Given equation,

2(x + 3) = 5x + 6 - 3x

Simplifying

2x + 6 = 2x + 6

LHS = RHS

Hence, equation 2(x + 3) = 5x + 6 - 3x  is always true.

Answer:

F & B

Step-by-step explanation:

Answer:

C, D, E

Step-by-step explanation:

Remote angles theorem; when one side of a triangle is extended, the angle formed must equal the sum of the two angles in the triangle, that it isn't adjacent to.

C. (m<4) > (m<1), this has to be true because of remote angles theorem.

(m<4) must be greater than (m<1) because it is equal to (m<1) + (m<2)

D. (m<4) > (m<2), apply the same logic here, as was applied to the first problem.

E. (m<1) + (m<2) = (m<4), this is essentially remote angles theorem.

Answer:

D, ininitely many

Step-by-step explanation:

A- incorrect since the lines intersect

B - incorrect since the lines intersect at more than one point

C - incorrect since the lines intersect at more than 2 points

D- correct since the lines intersect at infinitely many points (since they're the same line)

Answer:

D) infinitely many solutions

Step-by-step explanation:

we can see that the graphs shows two lines that are exactly one on top of the other. This means that every point on either line will also coincide with a point on the other line.

Because of this, every point on one line is also a solution on the other line, thus there are infinitely many solutions.

Step-by-step explanation:

Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us.

She found that of the 80 people who responded:

For fortnite:

0.55 of them preferred FortNite

Hence, = 0.55 × 80 people

= 44 people preferred fortnite

For Among us

30% of them preferred Among Us.

= 30% × 80 people

= 30/100 × 80 people

= 24 people preferred Among us.

How many more of her friends prefer FortNite than Among Us?

This is calculated as:

44 - 24

= 20 more people

Hence, 20 more of her friends prefer FortNite than Among Us
