Answer:

The correct answer is -4.

Step-by-step explanation:

have a good day yall

Evaluating the function, f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

To evaluate a function, plug in the given value of the input (x) and simplify.

Thus:

f(x) = –2x² – 3x + 5

Substitute x = -3 into the function

f(-3) = –2(-3)² – 3(-3) + 5

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

f(-3) = -4

Therefore, evaluating the function, f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

Answer:

The unit rate in miles per hour = 1.4 miles/hr

Step-by-step explanation:

Given that:

Distance walked by Boardman family = Two over five of a mile = [tex]\frac{2}{5}\ miles[/tex]

Time taken by Boardman family = Two over seven of an hour = [tex]\frac{2}{7}\ hour[/tex]

To find:

The unit rate in the miles per hour = ?

Solution:

Formula for the rate or the speed can be given as:

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Putting the values:

[tex]\Rightarrow \dfrac{\frac{2}5}{\frac{2}7}\\\Rightarrow \dfrac{7}{5}\\\Rightarrow \bold{1.4\ miles/hr}[/tex]

So, the unit rate in miles per hour = 1.4 miles/hr

D

Step-by-step explanation:

the answer should be D

Step-by-step explanation:

when looking this up it seems foil and multiplying binomial go hand and hand but this more closely resembles D

Answer:

the question is incomplete, so I looked for a similar one:

After the release of radioactive material into the atmosphere  from a nuclear power plant, the hay was contaminated by iodine  131 ( half-life, 8 days). If it is all right to feed the hay to cows  when 10% of the iodine 131 remains, how long did the farmers  need to wait to use this hay?

iodine's half life (we are given x, we need to find b):

0.5A₀ = A₀eᵇˣ

x = 8 days

we eliminate A₀ from both sides

0.5 = eᵇ⁸

ln 0.5 = ln eᵇ⁸

-0.69315 = b8

b = -0.69315 / 8 = -0.08664

since the farmers need to wait until only 10% of the iodine remains (we already calculated b, now we need to find x):

0.1A₀ = A₀eᵇˣ

0.1 = eᵇˣ

ln 0.1 = bx

where b = -0.08664

x = ln 0.1 / -0.08664  = -2.302585 / -0.08664  = 26.58 days

To find a function, for every x value there is only one corresponding y value.

If at x=-2, there are two values for y then it is NOT a function.

Answer:

The greatest number of bouquets Ms. Reyes can make is 4 bouquets

Step-by-step explanation:

Ms. Reyes buys three types of flowers. She buys 20 roses, 24 carnation, and 36 tulips.

To find the greatest number of bouquets she can make, we solve using Greatest Common Factor method.

We find the factors of 20, 24 and 36

The factors of 20 are: 1, 2, 4, 5, 10, 20

The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

Then the greatest common factor is 4.

Hence, the greatest number of bouquets Ms. Reyes can make is 4 bouquets

Step-by-step explanation:

Answer:

The outlier slightly affected the median.

Step-by-step explanation:

Given :

Data without an outlier: 15, 19, 22, 26, 29

Data with an outlier: 15, 19, 22, 26, 29, 81

The median :

Data without outlier :

0.5(n + 1) th term

n = 5

0.5(5 + 1) = 0.5(6) = 3rd term

3rd term = 22

Data with outlier :

0.5(n + 1) th term

n = 6

0.5(6 + 1) = 0.5(7) = 3.5th term

(3rd term + 4th term) /2

(22 + 26) / 2

48 / 2

= 24

From the result obtained ; The outlier slightly affected the median.

Answer:

A) The outlier slightly affected the median.

Step-by-step explanation:

Without the outlier, the median is 22, and with the outlier, the median is 24. So the outlier slightly affected the median.

 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

To find the slope of the graph, we use the expression below;

  Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]  

We pick two points; (-2, 1) and (4, 4)

  x₁  = -2,

  y₁ = 1

  x₂ = 4

  y₂  = 4

Now insert the parameters and solve;

  Slope  = [tex]\frac{4-1}{4- (-2)}[/tex]   = [tex]\frac{1}{2}[/tex]

Now, you can add them together to get 31/30, so a little more than a gallon

Answer:

2^3 * 7 + 7^2

Step-by-step explanation:

1) divide 28 by 2 = 14

2) divide 14 by 2 = 7

3) this means that 2 * 2 * 7 = 28

4) you can then take those 2 twos and multiply them with the first 2 and make 2^3

5) the square root of 49 is 7 so that is just 7^2

6) plug in all these new values for the originals and you get the answer above

Answer:

first you gotta calculate 2 -28 +49

After getting the answer solve the expressions to see which one is equivalent to 2-28 +49 (I think)
