Answer 1

Answer:

x= 33.9

Step-by-step explanation:

use cosine because x is the adjacent and 40 is the hypotenuse

set up your equation:

cos(32)= (x/40)

multiply both sides by 40:

40(cos(32))= (x/40)40

40(cos(32))= x

multiply 40 by the cos(32):

33.9 = x

Step-by-step explanation:

find the zero of the following function: f(x)=2/3(x)+6

Answers

x=-9.
explanation: You want to set the equation equal to 0, so 0=2/3x+6. Subtract 6 from each side... -6=2/3x. then multiply each side by the reciprocal of 2/3, or 3/2. The equation is now 6(3/2) = 2/3x(3/2). Knowing that the reciprocal of any number times itself =1, we can conclude that -18/2, or -9=1x.

Why is x = 6 a solution to the proportion 192/36 = 32/x ?

Answers

Because if 192/36 = 5.3333 and 32/6 = 5.3333 then the solution is right

Answer:

It is a solution because when you divide 192 by 36 you get 5 and one third. When you divide 32 by 6 you also get 5 and one third. This means they are equal.

Step-by-step explanation:

Im only a freshman, but i think i got it, i just assumed that the other small part at the bottom was also 20 degrees, which would mean that you are missing the 140 degrees from the 180 degree line

Answer:

120 degrees

Step-by-step explanation:

The bottom part is 40 degrees,

the two lines are parallel, so theoretically, you can just put them together. Then using vertical angles, you can tell it's 40 degrees.

40 + 20 = 60

180-60 degrees is 120 degrees.

A ball is thrown into the air from a height of 4 feet at time t=0. The function that models this situation is h(t)=-16t^2+63t+4. What will be the height of the ball after 2 seconds?

Answers

Answer:

66 feet

Step-by-step explanation:

We know that the t in the equation represents the time. So, substitute 2 for the t in the function and simplify to find the height after 2 seconds:

[tex]h(t) = -16t^2+63t+4\\h(2) = -16(2)^2+63(2)+4\\h(2) = -16(4)+126+4\\h(2) = -64 + 126+4\\h(2) = 66[/tex]

Thus, the height would be 66 feet.
