what is f(x)=4*(1/2)^x

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.

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%

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%

Answer:

x = 65 degrees

Step-by-step explanation:

Sum of all three sides in a triangle is 180

48 + 67 + n = 180

180 - (48 + 67) = 65

The missing angle and angle X are vertical angles, so they are the same angle.

angle X = 65 degrees

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

Should be 747.50 dollars

Step-by-step explanation:

So if your own a calculator you can simply type 1150 times .35 which is the percentage of 35 converted into a decimal , once you multiply you should get 402.5, you get that 402.5 and subtract it from 747.50 dollars

Answer:

Step-by-step explanation:

10%=115 so do 115 times 3 which is 345 so half that and and in terms of money that'll be 57.50 so do 345+57.50  and thats  $502.50

Answer:

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)

Coordinates of U' → (5, 4)

Answer:

-15

Step-by-step explanation:

Well you cleary just divide the numbers But if you dont belive it use a caculator for this

-210 divided by 14 equals -15.

To divide -210 by 14, we set up the division equation: -210 ÷ 14.

Since we have a negative dividend, we know the quotient will also be negative.

We divide the absolute values of the numbers: 210 divided by 14, which equals 15.

Since the dividend and divisor have different signs, the quotient is negative.

Therefore, -210 divided by 14 equals -15.

This means that -210 can be evenly divided into 14 groups, each having a value of -15.

The negative sign indicates that the result is in the opposite direction or orientation compared to the positive value.
