Answer:

31.

Step-by-step explanation:

1. Write out the problem.

6w-19 + k; w=8 and k=2

2. Figure out the first part of the problem.

So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.

3. Find out what the last part of the problem is.

Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.

Hope this helped :)

A line has a slope of 2 and passes through the point ( -1, 3). Write an equation in slope intercept form
stealth61 [152]

Answer:

y=2x+5

Step-by-step explanation:

The equation of a line in slope intercept form is written as: y=mx +b where m is the slope and b is the y-intercept.

Taking point (-1,3) , m= 2 and imaginary point on the line, (x,y) then ;

m=change is y-coordinates/change in x-coordinate

m=Δy/Δx

m=y-3/x--1

2= y-3 / x+1

2(x+1) = y-3

2x +2 =y-3

2x=y-3-2

2x=y-5

<u>y=2x+5 is the equation.</u>

The average high temperature during the hottest month in Beijing, China, is 72°F. The average high temperature during the coldes
Angelina_Jolie [31]

Answer:

- September

Step-by-step explanation:

The temperature in Beijing, in m months after January, is given by the following equation:

T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45

In which m is the number of months after January.

During which month in the year would the temperature reach 55°F?

We have to find m for which: T(m) = 55. So

T(m) = 27\cos{((\frac{\pi}{6})(m-6))} + 45

55 = 27\cos{((\frac{\pi}{6})(m-6))} + 45

27\cos{((\frac{\pi}{6})(m-6))} = 10

\cos{((\frac{\pi}{6})(m-6))} = \frac{10}{27}

Now, we apply the inverse cosine, on both sides of the equation, to find the value of m.

\cos^{-1}{\cos{(\frac{\pi}{6})(m-6)}} = \cos^{-1}{\frac{10}{27}}

Now, with the help of a calculator, in radians:

\frac{\pi}{6}(m-6) = 1.19

\pi m - 6\pi = 6*1.19

\pi m = 6*1.19 + 6 \pi

m = \frac{6*1.19 + 6 \pi}{\pi}

m = 8.27

8.27 months after January, since 8.27 + 1 = 9.28, it happens during the month of September.

A right triangle has a hypotenuse of 70 feet and a leg of 35 feet. What is the length of the other leg?
Hunter-Best [27]
We are given the two sides of the right triangle therefore we can use the pythagorean theorem to solve for the third side. This theorem states that, in a right triangle the square of the hypotenuse is equal to the sum of the square of each leg.

c² = a² + b²
70² = 35² + b²
b = √70² - 35²
b = 60.62 feet
