Answer:

$C = 28.9$

Step-by-step explanation:

Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.

Apply the trigonometric ratio formula to find m < C.

Adjacent side = 7

Hypotenuse = 8

Trigonometric ratio formula to apply would be:

$cos(C) = \frac{7}{8}$

$cos(C) = 0.875$

$C = cos^{-1}(0.875)$

$C = 28.9$

Factor the polynomial by grouping : x^3+5x^2-6x-30

andrew-mc [135]

The idea is to pair up the terms, factor each sub-group, and then pull out the overall GCF to fully factor.

x^3+5x^2-6x-30

(x^3+5x^2)+(-6x-30)

x^2(x+5)+(-6x-30)

x^2(x+5)-6(x+5)

(x^2-6)(x+5)

-------------

Answer: (x^2-6)(x+5)

Jim uses the function f(x) = 0.7x + 23 to determine the amount he charges for each used

morpeh [17]

Given that Jim uses the function f(x) = 0.7x + 23 to determine the amount he charges for each used drone he sells, where x is the original value of the drone and that the function g(x) = 1.08x is used to determine the amount a customer pays for a drone at Jim’s store including 8% sales tax.

 The function to determine the total amount a customer pays for a used drone at Jim’s store including 8% sales tax is given by

f(x) + g(x) = 0.7 + 23 + 1.08x = 1.78x + 23.

1. What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging th

Schach [20]

Answer:

The table is missing in the question. The table is provided below.

Step-by-step explanation:

1. In the table, it is given the difference of high temperature. They are :

-7, -7, 2, 5, -3, -2

Now adding the differences of high temperatures and taking out its average.

-7 + (-7) + 2 + 5 + (-3) + (-2)= -12

Average : $-\frac{12}{6}=-2$

Thus the answer is an integer.

2. In the table, it is given the difference of high temperature. They are :

0, -3, -7, -1, 1, 0

Now adding the differences of high temperatures and taking out its average.

0 + (-3) + (-7 )+ (-1) + 1 + 0= -10

Average : $-\frac{10}{6} = -1.66$

Thus, the answer is not an integer. The answer lies between the integers -2 to -1.
