What is the value of this function evaluated at f(-3): f(x) = 2x2+ 5x - 9? F -6 G -42 H 42 J 12

Answers

Answer:

f(-3) = -6

Step-by-step explanation:

f(x) = 2x^2+ 5x - 9

We are to find f(-3)

f(-3) = 2(-3)^2+ 5(-3) - 9

f(-3) = 2(9)-15 - 9

f(-3) = 18 -15 -9

f(-3) = 18-24

f(-3) = -6

Coordinates of W' → (3, 3)

Coordinates of U' → (5, 4)

Step-by-step explanation:

If the given figure is dilated about a point (4, 3) by a scale factor k = [tex]\frac{1}{2}[/tex]

Then the length of each side will get reduced to half of its original length.

(As in the figure attached)

Scale factor = [tex]\frac{\text{Side length of image}}{\text{Side length of preimage}}[/tex]

[tex]\frac{1}{2}=\frac{V'U'}{VU}[/tex]

V'U' = [tex]\frac{1}{2}(VU)[/tex]

Now from the graph,

Coordinates of W' → (3, 3)

illuminated.
PLEASE HELPPPPPPP!!!!!!!!!!!​

Answers

Answer:

Day 13= 50%

Day 26=100%

Step-by-step explanation:

Answers vary. Sample response: A simple approach is to attempt a linear model starting at Day 1. If the illumination is increased by 4% every day, then after 11 more days (after Day 2) it reaches 50%. In 13 more days, illumination reaches 100%. This gives a prediction of Day 13 for 50% and Day 26 for 100%.

The days where it is illuminated is Day 13= 50% and Day 26=100%

Linear model:

Here A simple approach should be considered for linear model that begins at Day 1. In the case when the illumination is increased by 4% every day, so after 11 more days (after Day 2) it reaches 50%. In 13 more days, illumination reaches 100%.

Therefore, we can conclude that The days where it is illuminated is Day 13= 50% and Day 26=100%

Find the equation of the linear function represented by the table below in slope- intercept form. х: -2, 2, 6, 10 y: -5, 7, 19, 31​

Answers

Answer:

y = 3x + 1

Step-by-step explanation:

Slope-intercept form is y = mx + b.

To find the slope (m), you use the equation (y1-y2)/(x1-x2). Plug in your points (-2, -5) and (2, 7) to get (-5 - 7)/(-2 - 2). Simplify the formula to get a slope of 3. This is your variable m.

To get the entire equation, finding b in the process, you use the formula y - y1 = m(x - x1). Replace m with 3. Using the point (-2, -5), replace it with (x1, y1) respectively to get y + 5 = 3(x + 2). Distribute to get y + 5 = 3x + 6. Isolate the y to get your final answer: y = 3x + 1.
