Answer: The velocity of the ball is 108.8 ft/s downwards.
Step-by-step explanation:
When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:
g = 32 ft/s^2
To get the velocity equation we need to integrate over time, to get:
v(t) = (32ft/s^2)*t + v0
where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)
Because it is dropped, the initial velocity is equal to zero, then we get:
v(t) = (32ft/s^2)*t
Which is the same equation that we can see in the hint.
Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:
v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s
The velocity of the ball is 108.8 ft/s downwards.

Jane was playing a game with her sister, Sally. Jane was down by 7. After her next turn, she was down by 3. Which of the following mathematical statements represents this scenario?
A. - 7 + -3 = -10
B.
- 7 + 3 = - 4
C. - 7+ 4 = - 3
D. - 7 + - 4 = - 11
Answer:
A. -7 + -3 = -10
Step-by-step explanation:
Jane went down by 7, so -7. Then, she went down by 3, so -7 + -3.
-7 + -3 = -10

Answer:
x=28°
Step-by-step explanation:
2x+3x-10+50=180
5x+40=180
5x=180-40
5x=140
x=140/5
x=28°
The angle measure of a triangle are shown in the diagram.
What is the value of x?
Answer :value of x is 28°Explanation :Given :∠A = 50°∠B = (2x)°∠C = (3x - 10)° To Find :Value of x = ?Solution :As, In a triangle measure of all three angles is always 180°.
[tex] \sf : \implies \angle A + \angle B + \angle C = 180\degree[/tex]
[tex] \sf : \implies 50\degree + (2x)\degree + (3x - 10)\degree = 180\degree[/tex]
[tex] \sf : \implies 50 + 2x + 3x - 10 = 180\degree[/tex]
[tex] \sf : \implies 40 + 5x = 180\degree[/tex]
[tex] \sf : \implies 5x = 180\degree - 40\degree[/tex]
[tex] \sf : \implies 5x = 140\degree[/tex]
[tex] \sf : \implies x = \cancel{\dfrac{140\degree}{5}}[/tex]
[tex] \sf : \implies x = 28\degree[/tex]
[tex] \large \underline{\boxed{\bf{x = 28\degree}}}[/tex]
Hence, value of x is 28°.
Which conic section is represented by the following equation?
5x^2 – x + 5y^2 – 3y + 4 = 0
circle
ellipse
parabola
hyperbola
Answer:
3 rd one
Step-by-step explanation:
The conic section represented by the given equation is Circle.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Standard form of a circle is,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Expanding, we get,
x² - 2hx + h² + y² - 2ky + k² = r²
x² - 2hx + y² - 2ky + (h² + k² - r²) = 0
The given equation is,
5x² – x + 5y² – 3y + 4 = 0
This is same as the standard form of the circle.
Hence the given equation is that of a circle.

3(2c + 5) = 39
What is the answer ?
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying
c = 1
Answer:

Step-by-step explanation:
Subtract 15 from both sides of the equation
6+15=39
6+15−15=39 − 5

6=24
Divide both sides of the equation by the same term

Step-by-step explanation:
y=ax
and plug x and y into the parent function.
Answer:
f(x) = -⁴/₃x + 6Step-by-step explanation:
f(0) = 6 means y-intercept b = 6
So we have:
f(x) = mx + 6 and f(3) = 2
So:
2 = m×3 + 6
3m + 6 = 2
3m = 2 - 6
3m = -4
m = -⁴/₃
Therefore the function:

Roy has $30 in a savings account. The interest rate is 10% per year and is not
compounded. How much will he have in 4 years?
Answer:
$43.92
Step-by-step explanation:
1st year:
30 x 10% = 3
30 + 3 = 33
2nd year:
33 x 10% = 3.3
33 + 3.3 = 36.3
3rd year:
36.3 x 10% = 3.63
36.3 + 3.63 = 39.93
4th year:
39.93 x 10% = 3.99
39.93 + 3.99 = 43.92

Angles 1 and 2 are supplementary. If angle 1 measures (2x +2)°, and angle 2 measures (x - 5)° what is the measure of each angle?
Answer:
angle 1 is = 124 angle 2 is = 56
Step-by-step explanation:
supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.
Help me ??????????????????
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = - 2x² - 12x - 16
To complete the square the coefficient of the x² term must be 1
Factor out - 2 from - 2x² - 12x
f(x) = - 2(x² + 6x) - 16
add/ subtract ( half the coefficient of the x- term )² to x² + 6x
f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16
= - 2(x + 3)² + 18 - 16
= - 2(x + 3)² + 2 ; y = 2
6 x 16 = 6 x ( _ + 6 )
= (6 x _ ) + ( 6 x _ )
= _ + _
= _ square units

Order from least to greatest.
68%, 0.687, 20
Answer:
20, 68%, 0.687
Step-by-step explanation:
If 20 were to be a percentage, then it'll be less than 68% and 0.687. Since the 7 in 0.687 is greater than 5, you would round up when the question says so. 0.687 is greater than 68%; if you move the decimal 2 times to the right, then 0.687 would be 68.7%. Therefore the order from least to greatest is 20, 68%, 0.687.
