What is the y - intercept?

A. 0
B. 1
C. 2
D. 7​

Answer:

The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

A linear graph has an equation in the form y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y at x = 0).

a) y represent the number of hours worked and x represent the number of weeks. The points are represented in the form (x, y).

First we can find the slope of the line by picking two points from the graph. Let us use (0, 0) and (2, 10). The slope m is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{10-0}{2-0} \\\\m=5[/tex]

The slope and constant of proportionality is 5.

b) The equation can be gotten using the points (0, 0) and (2, 10). Therefore:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-0=\frac{10-0}{2-0}(x-0)\\\\y=5x\\\\[/tex]

c) In 16 weeks (i.e. x = 16):

y = 5x

y = 5(16)

y = 80 hours

The translations of the graph of the parent function [tex]f(x) = x^2[/tex]  that result in the graph of [tex]g(x) = (x + 2)^2 + 6[/tex] will be that the parabola moved  [tex]2[/tex]  units to the left and  [tex]6[/tex] units up.

Translation is the act or process of changing completely. In this also the graph changes or transform. i.e. in the graph values of the expression are changing and forming new shape.

We have,

Parent Quadratic equation   [tex]f(x) = x^2[/tex]

And,

Translation of graph  [tex]g(x) = (x + 2)^2 + 6[/tex]

So,

Parent quadratic function works in the form of  [tex]f(x) = a(x-h)^2 + k[/tex]

Here,

"h" tells if the vertex of the parabola is going left or right.

"k" determines if the vertex of the parabola is going up or down.

So, According to the question;

We have,

Translation of graph  [tex]g(x) = (x + 2)^2 + 6[/tex]

So,

From equation we find out that the vertex of the parabola moved  [tex]2[/tex]  units to the left and  [tex]6[/tex] units up.

(Always remember if moving left means  sign would be of plus because in parent quadratic function is in the form of  [tex]f(x) = a(x-h)^2 + k[/tex]  we have minus sign in it.)

Hence, we can say that the Translation of the graph of the parent function [tex]f(x) = x^2[/tex]  that result in the graph of [tex]g(x) = (x + 2)^2 + 6[/tex] will be that the parabola moved  [tex]2[/tex]  units to the left and  [tex]6[/tex] units up.

Force = mass × acceleration

acc= force / mass

84N/89kg

= 0.94m/s

The acceleration of the runner is 0.9 m/[tex]s^{2}[/tex].

We have a runner has a mass of 89 kg he produces a force of 84 Newtons between the ground and his running shoes.

We have to determine the acceleration of the runner.

The force on a body is the product of mass and acceleration. Mathematically -

F = ma

According to the question, we have -

Force = 84 N

Mass = 89 Kg

Therefore -

F = ma

84 = 89 x a

a = 84/89 = 0.9 m/[tex]s^{2}[/tex]

Hence, the acceleration of the runner is 0.9 m/[tex]s^{2}[/tex].

Answer:

Ariana has 7 dimes and 14 nickels

Step-by-step explanation:

Nickel = 0.05

Dime = 0.10

1.40 ÷ 2 = 0.70

7 x 2 = 14

because Adriana has twice the nickels as dimes and half of the 1.40 is dimes so the other half is nickels.

nickels x 2 = 14

Answer:

The 8th term of the geometric sequence 5, -15, 45, ... is:

[tex]a_8=-10935[/tex]

Step-by-step explanation:

Given the geometric sequence

5, -15, 45, ...

The first element of the geometric sequence is

[tex]a_1=5[/tex]

A geometric sequence has a constant ratio 'r' and is defined by  

[tex]a_n=a_1\cdot r^{n-1}[/tex]

computing the ratios of all the adjacent terms

[tex]\frac{-15}{5}=-3,\:\quad \frac{45}{-15}=-3[/tex]

The ratio between all the adjacent terms is the same and equal to

[tex]r=-3[/tex]

substituting [tex]a_1=5[/tex], and [tex]r=-3[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=5\left(-3\right)^{n-1}[/tex]

Determining the 8th term:

We have already got the nth term

[tex]a_n=5\left(-3\right)^{n-1}[/tex]

substituting n = 8 to determine the 8th term

[tex]a_n=5\left(-3\right)^{n-1}[/tex]

[tex]a_8=5\left(-3\right)^{8-1}[/tex]

[tex]a_8=5\left(-3^7\right)[/tex]

[tex]a_8=-5\cdot \:3^7[/tex]

[tex]a_8=-5\cdot \:2187[/tex]

[tex]a_8=-10935[/tex]

Therefore, the 8th term of the geometric sequence 5, -15, 45, ... is:

[tex]a_8=-10935[/tex]

Given: 3ln2 +ln8=2ln(4x)

          ⇒ln [tex]2^{3}[/tex]+ln8=2ln(4x)            ( m ln (n)= ln([tex]n^{m}[/tex]))

             ⇒ ln8+ln8= 2ln(4x)

            ⇒ 2ln8= 2ln(4x)

   comparing both sides, we get

  8=4x

  ⇒x=2

Answer:

The surface area of the pyramid is 340.2 cm²

Step-by-step explanation:

We can find the surface area of this pyramid by adding up the area of its square base and the four side triangles.

We're told that the base has a side length of 9.0 cm, so we know that its area is (9.0cm)², or 81cm²

We are told that the height of the side triangles is 14.4 cm.  To find the area of a triangle, simply multiply its width times its height, and divide by two:

(14.4cm × 9cm) ÷ 2

= 129.6cm² ÷ 2

= 64.8 cm²

Now we can multiply that by 4, and add it to the base area to get the total surface area of the pyramid:

4 × 64.8cm² + 81cm²

= 259.2cm² + 81cm²

= 340.2cm²
