the rate of change is -2 for every set shown in the chart on the right

so 6 to 7 would be -11 -2 = -13

7 to 8 would be -13-2 = -15

8 to 9 = -15-2 = -17

B is the answer

A football is kicked into the air. The height of the football can be modeled by the equation

Alinara [238K]

Answer:

x = 0 and x = 1

Step-by-step explanation:

Given that,

A football is kicked into the air. The height of the football can be modeled by the equation :

$h = -16x^2 + 16x$

Where

h is the height reached by the ball after x seconds

When it touches the ground, h = 0

So,

$-16x^2 + 16x=0\\\\16x(-x+1)=0\\\\x=0\ and\ x=1$

So, it will touch the ground at x = 0 and x = 1 seconds.

Using the equation of the line (y = 0.5x + 79), what would be the melting point of dna with 50% gc content? enter your answer as

steposvetlana [31]

We have the equation of the line as follows:
y = 0.5x + 79

We want to calculate the melting point (the y value) of DNA with 50% gc content (the x value).
The gc content represents the value of x in the equation, so to calculate the melting point (y), we will simply substitute the x with 50 in the equation of the line as follows:
melting point = 0.5(50) + 79 = 25 + 79 = 104 degrees

What is the image point of (-12, -8) after the transformation R270° 0 D. ?

Gennadij [26K]

Given:

The point is (-12,-8).

Rule of transformation is $R_{270^\circ}\circ D_{\dfrac{1}{4}}$ .

To find:

The coordinates of image after transformation.

Solution:

According to the rule of transformation $R_{270^\circ}\circ D_{\dfrac{1}{4}}$ , first the point is dilated by factor $\dfrac{1}{4}$ with origin as center of dilation after that it was rotated 270 degrees anticlockwise.
