Answer:
1001 m/s
300 [tex]m/s^2[/tex]
0.299.
Step-by-step explanation:
Given that:
[tex]D=f(t)=t^3+1[/tex]
[tex]f(10)[/tex] means putting the value of [tex]t=10[/tex] in [tex]f(t)[/tex].
[tex]f(10) = 10^3+1=1001[/tex] [tex]m/s[/tex]
To find [tex]f'(10)[/tex], we need to find [tex]f'(t)[/tex] first.
Differentiating the equation of Distance [tex]D[/tex] w.r.to [tex]t[/tex]:
[tex]f'(t) = \dfrac{d}{dt}(t^3+1)= 3t^{3-1}+1 = 3t^2[/tex]
[tex]f'(10) = 3(10)^2=300[/tex] [tex]m/s^2[/tex]
Relative rate of change:
[tex]\dfrac{f'}{f}\ at\ t = 10 \Rightarrow \dfrac{300}{1001} \approx 0.299[/tex]
A gumball machine has 300 red gumballs. If the red gumballs are 75% of the total number of gumballs, how many gumballs are in the gumball machine?

400
BRAINLIST,EXTRA POINTS, 5 STARS, AND HEART
Answer:
The answer is 400
Step-by-step explanation:
Percent is to 100 as part is to whole.
In this case we have no whole but we have a part, and we have a percentage. 100% is equal to the whole so, 300 divided by 4 is 75 and what you do on the top is what you do on the bottom; 100x4=400

A penny is thrown from the top of a 26.6-meter building and hits the ground 3.59 seconds after it was thrown. The penny reached its maximum height above the ground 0.77 seconds after it was thrown.
1. Define a quadratic function, h, that expresses the height of the penny above the ground (measured in meters) as a function of the number of seconds elapsed since the penny was thrown, t.
2.What is the maximum height of the penny above the ground?
Answer:
it is at 200 mph
Step-by-step explanation:
bc i did the test
The quadratic function which models the motion of the penny is h(t) = -4.9t² + 10.18t + 26.6 and the maximum height reached is 31.53 meters
The relationship can be expressed in the form :
h(t) = - 0.5gt² + vt + h (downward motion)
g = 9.8 m/s²
h = 26.6 m
v = ?
We can obtain v thus ;
h(t) = -0.5gt² + vt + 26.6
h(t) = - 4.9t² + vt + 26.6
Time when penny hits the ground ; t = 3.59
h(3.59) = 0
0 = -4.9(3.59)² + v(3.59) + 26.6
− 63.15169 + 3.59v + 26.6 = 0
3.59v = 36.55169
v = 36.55169 /3.59
v = 10.181 m/s
Equation becomes :
h(t) = -4.9t² + 10.18t + 26.6
2.) The maximum height of the penny above the ground ;
t = 0.77 secondsh(0.77) = -4.9(0.77^2)+ 10.18(0.77) + 26.6
Maximum height reached = 31.53 meters
Therefore, the maximum height reached is 31.53 meters

solve for y
Answer: [tex]y=\frac{-x}{w-3}[/tex]
Step-by-step explanation:
To solve for y, we want to isolate y.
[tex]w=\frac{3y-x}{y}[/tex] [multiply both sides by y]
[tex]yw=3y-x[/tex] [subtract both sides by 3y]
[tex]yw-3y=-x[/tex] [factor out y]
[tex]y(w-3)=-x[/tex] [divide both sides by (w-3)]
[tex]y=\frac{-x}{w-3}[/tex]
Now, we know that [tex]y=\frac{-x}{w-3}[/tex].

What is the first step needed to solve 4 over 7 multiplied by x minus 5 equals negative 13? Subtract 13 from both sides Divide both sides by 7 Add 5 to both sides Multiply both sides by 4
Answer: C) add 5 to both sides
The given equation is
(4/7)x - 5 = -13
To solve this, we follow PEMDAS in reverse undoing each operation. Normally parenthesis is the first thing we look for, but instead we start with subtraction.
So we'll undo subtraction which means we add 5 to both sides
