Answer:

0.18 sec or 3.4 sec.

For second part, it will take 3.7 sec.

First part:

Set h(t) = 17and solve for t.

-16t²+ 58t + 7= 17

-16t² + 58t - 10 = 0

Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.

Second part:

Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.

Sage hiked from the start of the trail to look out point. she then hiked back to giant boulder to camp for the night. what was t

Stolb23 [73]

Distance from start to look out point is calculated below
d1 = 8 3/4 miles - 0 miles = 8 3/4
Distance from look out point to giant boulder is,
d2 = 8 3/4 miles - 4 1/4 miles = 9/2 miles = 4.5 miles
Thus, the answer is equal to 4 1/2 miles. The answer is letter C.

P=3y/q solve for y make sure to add steps pls

Likurg_2 [28]

Answer:

Solving for y gives:

$y = \frac{pq}{3}$

Step-by-step explanation:

Linear equations are the equations that are degree one equations. When it is asked to solve an equation for a specific variable that means that the specified variable has to be isolated on one side of the equation i.e. in the given question solving for y means isolating y on one side of the equation.

Given equation is:

$p = \frac{3y}{q}$

Multiplication property of equality(Multiplying both sides by q)

$p*q = \frac{3y}{q} * q\\pq = 3y$

Division property of equality(Dividing both sides by 3)

$\frac{pq}{3} = \frac{3y}{3}\\\frac{pq}{3} = y$

Hence,

Solving for y gives:

$y = \frac{pq}{3}$

Which expression are of -48xyz+24xy+40xyz

Anon25 [30]

Answer:

I'm GUESSING you want to know which are possible FACTORS of the equation. - 48xyz + 24xy + 40xyz

IF so,

THEN

A) 4 as 48, 24, and 40 divide evenly by 4

4(-12xyz + 6xy + 10xyz)

D) 8Y as 48, 24, and 40 divide evenly by 8 and each term has a Y

8y(-6xz + 3x + 5xz)

E) 2XY as 48, 24, and 40 divide evenly by 2 and each term has a XY

2xy(-24z + 12 + 20z)

I need help on knowing whether this is a solvable equation. Along with reasons why. HELP IF YOU CAN :))

leva [86]

To check if x = 9 is the solution, we need to replace every x with 9 and simplify

(3+x)/4 = 3

(3+9)/4 = 3

12/4 = 3

3 = 3

We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.
