Rachel is a stunt driver, and she's escaping from a building that is about to explode!
The variable d models Rachel's distance from her exit (In meters) t seconds after the cameras began recording the stunt
What is Rachel's speed?
Answer:
The variable d models Rachel's distance from her exit (in meters) t seconds after the cameras began recording the stunt. d = - 38t
Step-by-step explanation:
From given, we have, The expression that represents the Rachel's distance is given by, d = - 38t + 220
where, d represents the distance in meters
t represents the time in seconds
We know that, speed = distance by time. Therefore, we need to differentiate the given equation w.r.t to time to find the speed.
we have, d/dt (d) = d/dt [- 38t + 220]
| d/dt (d) | = | - 38 + 0 |
s = d/dt (d) = 38 m/s
Therefore, the speed of Rachel is 38 m/s.
Answer:
38 meters per second

enter the value of P so that the expression 4(10+n) is equivalent to 4(n+p)
Answer:
I think it is 10
Step-by-step explanation:
Only because I believe n is still unknown and 4 must be multiplied
example
4(10 + n)
40 + 4n
now if P = 10
4(n + p)
4(n + 10)
4n + 40
Answer:
P=10
Step-by-step explanation:
4(10+n)=4(n+p)
40+4n=4n+4p
40=4p+4n-4n
40=4p
p=10
n=0

In parallelogram ABCD, if ED = 7x - 13 and BD = 16x - 38, find BD.
Answer:
58
Step-by-step explanation:
The length of BD is 58 units.
What are properties of parallelogram?The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal. A parallelogram's total square sum and total square sum of its diagonals are equivalent. Additionally known as the parallelogram law.
Given:
ED = 7x - 13 and BD = 16x - 38
So, the Diagonals of parallelogram bisect each other
BD = ED+ EB
16x - 38 = 2 ED { ED= EB}
16x - 38 = 2 (7x- 13)
16x - 38 = 14x - 26
2x = 12
x= 6
So, length of BD = 16(6) - 38 = 96- 38 = 58 units

A ladder is leaning against
a brick building as shown in the figure. What
is the length of the ladder?
x ft
20 ft
15 ft
Answer:
25 ft
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 20 ^2 = x^2
225+400= x^2
625 = x^2
Take the square root of each side
sqrt(625) = sqrt(x^2)
25 = x

Step-by-step explanation:
6x+4=8
Subtract 4 from both sides.
6x=4
Divide both sides by 6
x=4/6
Simplify it
x=2/3
3x+2=4
Subtract both sides by 2
3x=2
Divide both sides by 3
x=2/3
Hope this helps
Answer and Step-by-step explanation:
The correct answer choice is answer choice 3. [ 3x + 2 = 4 ]
6x + 4 = 8
6x = 4
x = 2/3

Kenny wants to learn how to serve overhand in volleyball. When he practiced yesterday, he made 7 serves over the net for every 2 serves that did not go over the net.If Kenny attempted 36 serves yesterday, how many serves did he make over the net?
Answer: 28
Step-by-step explanation:
Given
Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is
[tex]\Rightarrow \text{success rate}=\dfrac{7}{2+7}\times 100=\dfrac{700}{9}\%[/tex]
for 36 serves, applying the same success rate, it is
[tex]\Rightarrow \text{success rate}=\dfrac{700}{9}\times\dfrac{1}{100}\times 36=28[/tex]
Serves that did not make over the net is [tex]36-28=8[/tex]
Thus, Kenny will make 28 serves that make over the net
