Rule: If x-k is a factor of p(x), then p(k) = 0. This is a special case of the remainder theorem.

Using that rule, we can see that x+5 is really x-(-5) so k = -5. 

Therefore,

p(k) = 0
p(-5) = 0

so the answer is choice D.

The area under the curve between the two values is (d) 0.0750

<h3>How to determine the area?</h3>

From the table, we have:

P(z = -0.45) = 0.3264

P(z = -0.67) = 0.2514

The area under the curve is calculated as:

Area = P(z = -0.45) - P(z = -0.67)

So, we have:

Area = 0.3264 - 0.2514

Evaluate the difference

Area = 0.0750

Hence, the area under the curve between the two values is (d) 0.0750

42 point Plus brainliest slove it g(x) = (x + 2)(x − 1)(x − 2)
Dmitry_Shevchenko [17]

Answer:

x = -2,1, 2

Step-by-step explanation:

g(x) = (x + 2)(x − 1)(x − 2)

Assuming we are looking for the roots

0  = (x + 2)(x − 1)(x − 2)

Using the zero product property

0 = x+2    0 =x-1    0 = x-2

x=-2         x = 1            x =2

➷ Writing it out like this will help:

7 : 3 : 2

? : 3.75 : ?

So, 3.75 is 3 parts as per this ratio

Divide this amount by 3 to get 1 part in the ratio

3.75 / 3 = 1.25

Now simply multiply all the other ratios by this value to find how much the others get:

1.25 x 7 = 8.75

1.25 x 2 = 2.5

Paula gets £8.75 and Henry gets £2.50

The amount altogether would be their individual amounts added together:

8.75 + 2.50 + 3.75 = 15

The total amount of money is £15.

Question 9 ONLY!!! Please show work!!

<h2>$40,000</h2>

Step-by-step explanation:

Andrew paid 30% in taxes, which means he has 70% remaining

30% Cash Prize + 70% Cash Prize = 100% Cash Prize

If C = Original Cash Price

Remaining Cash = 70% x C = $28,000

C = $28,000 / 70% = 28000/0.7 = $40,000
