Answer:

(c)

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos42°  = \frac{adjacent}{hypotenuse} = \frac{x}{12}

Multiply both sides by 12

12 × cos42° = x, hence

x ≈ 8.9 → (c)

What is the value of x? -2x + 8 = - 16
umka2103 [35]
Solve the equation
So first we subtract 8 from both sides because we apply the inverse operation.
-2x+8=-16
     -8      -8
Now we apply it and re write the equation
-2x=-24
Now the inverse operation for multiplication is division, so we apply it.
-2x=-24
------------
 -2      -2
We are left with x=8
So our final answer is x=8

Check our work
-2(8)+8=-16

CORRECT ANSWER. :)

Answer:

C

Step-by-step explanation:

The slope m of the functions give the measure of the rate of change.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

g(x) = \frac{5}{2} x - 3 ← is in slope- intercept form

with slope m = \frac{5}{2} = 2.5

Calculate the slope of f(x) using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 3.5) and (x₂, y₂ ) = (1, - 1) ← 2 points from the table

m = \frac{-1+3.5}{1-0} = 2.5

Hence

The slopes of g(x) and f(x) are both m = 2.5, thus

The functions increase at the same rate → C

Determine the point estimate of the population​ proportion, the margin of error for the following confidence​ interval, and the
PilotLPTM [1.2K]

Answer:

point of estimate p = x/n

Step-by-step explanation:

p is the point estimate for the population , x is the number of success, n is the sample size.

p = Upper bound  + Lower bond/ 2      for population proportion

x = Upper bond + Lower bond /2          for population mean

E = Upper bond - Lower bond /2          E is margin of error
