the coordinates of the vertices of the image after a dilation with the
origin as the center of dilation and a scale factor of 3.5? *
O (-14, -14), (-21, 14), (21, 28), and (35, 7)
(-6, -6), (-9,6), (9, 12), and (15,3)
(-10, -10), (-15, 10), (15, 20), and (25,5)
(-12, -12),(-18, 12), (18, 24), and (30, 6)

Answers

Answer:

I'll do the dilation for the first point and you will see the answer (please verify the second point)

Step-by-step explanation:

The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.

so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.

so the dilated point for (-4,-4) is (-14, -14)

Please verify by computing the dilated point for (-6,4)

The giant panda population in China is increasing at a rate of 1.5% each year. There are 1864 giant panda in 2014. Write a function that models the panda population since 2014.

(exponential growth & decay)

Answers

Given:

Giant panda population in 2014 = 1864

The giant panda population in China is increasing at a rate of 1.5% each year.

To find:

The function that models the panda population since 2014.

Solution:

Since population of giant panda is increasing, therefore the function is the exponential growth model.

The general exponential growth model is:

[tex]P(t)=P_0(1+r)^t[/tex]

Where, [tex]P_0[/tex] is the initial population, r is the growth rate in decimal and t is the time period.

Putting [tex]P_0=1864,r=0.015[/tex], we get

[tex]P(t)=1864(1+0.015)^t[/tex]

[tex]P(t)=1864(1.015)^t[/tex]

Where, t is the number of years since 2014.

Therefore, the required exponential growth model is [tex]P(t)=1864(1.015)^t[/tex].

A parabola can be drawn given a focus of (4, -8) and a directrix of y=-6
. What can be said about the parabola?

Answers

Answer:

y = 1/4 (x-4)² - 7

Step-by-step explanation:

Point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

√(x-4)²+(y- -8)² = √(y- -6)²

(x-4)² + (y+8)² = (y+6)²

(y+8)² - (y+6)² = (x-4)²

(y²+16y+64) - (y²+12y+36) = (x-4)²

y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

4y = (x-4)² - 28

y = 1/4 (x-4)² - 7

standard formula of parabola: y = a(x-h)² + k      (h,k): vertex (4,-7)

The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

What is Parabola?

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line, which is known as the directrix.

Now,

Let a point (x , y) on the parabola, focus of (4, -8) and a directrix of y= -6

Hence, We can formulate;

⇒ √(x-4)²+(y- (-8))² = √(y- (-6))²

⇒ (x-4)² + (y+8)² = (y+6)²

⇒ (y+8)² - (y+6)² = (x-4)²

⇒ (y²+16y+64) - (y²+12y+36) = (x-4)²

⇒ y²+16y+64-y²-12y-36 = 4y+28 = (x-4)²

⇒ 4y = (x-4)² - 28

⇒ y = 1/4 (x-4)² - 7

Thus, The value of equation of parabola is,

⇒ y = 1/4 (x-4)² - 7

B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60

Answers

Answer:

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

From the above question, one of the angles = 60°

The value for the two other interior angles = 180° - 60° = 120°

Hence, the following options could be the values of x and y is given as x + y = 120

Therefore,

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Answers

Answer:

Step-by-step explanation:

im pretty sure this answers your question

The standard form of the vertex form equation is y = 2x² - 12x + 17

How to convert the equation?

The vertex form of a quadratic equation is represented as:

y = a(x - h)² + k

Using the above form, the quadratic equation can be represented as:

y = 2(x - 3)² + 1

Expand

y = 2(x² - 6x + 9) - 1

Further expand

y = 2x² - 12x + 18 - 1

Evaluate the like terms

y = 2x² - 12x + 17

Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items?

Answers

Answer:

Total amount pay by Ben = $82.27 (Approx.)

Step-by-step explanation:

Given:

2 Shirts = $16 each

3 pairs of socks = $2.50 each

1 pair of jeans = $37.75 each

Sales tax = 6.5%

Find:

Total amount pay by Ben

Computation:

Total amount for shirts = 2 x 16

Total amount for shirts = $32

Total amount for socks = 3 x 2.50

Total amount for shirts = $7.50

Total amount before tax = $32 + $7.50 + $37.75

Total amount before tax = $77.25

Total amount pay by Ben = Total amount before tax[1+tax]

Total amount pay by Ben = 77.25[1+6.5%]

Total amount pay by Ben = $82.27 (Approx.)
