Answer: -5x+6

Step-by-step explanation:

Find slope through slope formula (y₂-y₁)/(x₂-x₁)

  • By doing this you find that the slope is -5

Then the y-intercept is found through the intersection of the y-axis.

I'm assuming you meant:

tan^{2}x + tanx - 30 = 0
Let u = tan(x)

Thus, we can rewrite it into a quadratic.

u^{2} + u - 30 = 0
(u + 6)(u - 5) = 0
u = -6 or u = 5

Hence, tan(x) = -6 or tan(x) = 5
x = tan^{-1}(-6) or x = tan^{-1}(5)

Rewriting it in general form, we get:
x = \pi \cdot n + tan^{-1}(5), n \in Z
x = \pi \cdot n - tan^{-1}(6), n \in Z

From there, you can find your solutions from [0, 2\pi)

The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the golf balls it manufactures. G
Mashutka [201]

Discrepancy is the difference of a the value from the uniform distribution. The function for the given situation can be given as,

f(x)=|x|-42.67

Hence the option 2 is the correct option.

Given information-

The standard diameter of the golf ball is 42.67 mm.

The discrepancy in the diameter is 0.004 mm.

<h3>What is discrepancy?</h3>

Discrepancy is the difference of a the value from the uniform distribution.

Suppose the discrepancy is x mm.

If the discrepancy in diameter is more than 0. 004 mm, the production is stopped.

As the discrepancy of 0.004 mm or more is stopped the production, we have to subtract the diameter to the discrepancy .

Thus the function for the situation can be given as,

f(x)=-42.67+|x|

Rearrange for the x,

f(x)=|x|-42.67

Thus the function for the given situation can be given as,f(x)=|x|-42.67

Hence the option 2 is the correct option.

Billy is 6 years younger than Amy. The sum of their ages is 22. How old will each of them be in 8 years?
Dafna11 [192]
First let's find their current ages:
Billy + 6years = Amy
Billy + Amy = 22

Combining these equations:
Billy + (Billy + 6years) = 22
2 Billy = 16
Billy = 8

Billy + 6 = Amy
8 + 6 = Amy
Amy = 14

In 8 years Billy will be 16 and Amy will be 22. The answer is d.
