Answer:

A = 26.6°

Step-by-step explanation:

To obtain the measure of angle A :

We use the trigonometric relation :

Tan A = opposite / Adjacent

Tan A = 6 / 12

Tan A = 1/2

A = tan^-1(1/2)

A = 26.565°

A = 26.6°

Which graph represents the function<br>there are 2 more graphs but it won't add it

Anon25 [30]

Answer:

$f(x) = 9x^2+9x - 18/3x + 6\\= 9(x^2 + x - 2)/3(x+2)\\= 3(x^2+x-2)/x+2\\= 3(x+2)(x-1)/x+2\\= 3x - 3$

so y = 3x - 3

since 3x + 6 is on the bottom,

$3x + 6\neq 0\\3x\neq -6\\x\neq -2$

so this means it should be the graph of y = 3x - 3, but with a hole at (-2, -9)

Help me in this plz....

Answer:

70. 8x⁴

71. 3n - 10

72. a/5 + 12

Step-by-step explanation:

70. a number "x" raised to the fourth = x⁴

Product of 8 and x⁴ = 8 × x⁴

= 8x⁴

71. 3 times a number "n" = 3 × n = 3n

3n decreased by 10 = 3n - 10

72. Quotient of a number "a" and 5 = a/5

12 more than a/5 = a/5 + 12

Consider a project that has an expected completion time of 60 weeks and a standard deviation of five weeks. What is the probabil

Nana76 [90]

Answer: 0.3413

Step-by-step explanation:

Given :Mean : $\mu=60\text{ weeks}$

Standard deviation : $\sigma = 5\text{ weeks}$

The formula for z -score :

$z=\dfrac{x-\mu}{\sigma}$

For x= 60 ,

$z=\dfrac{60-60}{5}=0$

For x= 65 ,

$z=\dfrac{65-60}{5}=1$

The p-value = $P(0$

$= 0.8413447-0.5= 0.3413447\approx0.3413$

Hence, the probability that the project will take anywhere between 60 and 65 weeks to complete = 0.3413.
