5. After t seconds, a ball tossed in the air from the ground level reaches a height
of h feet given by the function h(t) = 144t – 16t^2. PART A: What is the height of
the ball after 3 seconds? PART B: After how many seconds will the ball hit the
ground before rebound? -
Answer:
a = 288 feet, b = 9 seconds
Step-by-step explanation:
t = 3, solve for h(t)
h(3) = 144(3)-16(3)^2
=432-144
=288
H(t) = 0, solve for t
0=144(t)-16(t)^2
t = 0, t =9
4x + 5y = 22
7x - 3y = -32
Answer:
x = -2
y = 6
Step-by-step explanation:
i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out
12x + 15y = 66
+ 35x - 15y = -160
47x = -94
x = -94/47
x = -2
substitute -2 for 'x' to solve for 'y':
4(-2) + 5y = 22
-8 + 5y = 22
5y = 30
y = 6

Step-by-step explanation:
A triangle has a base of 7 feet and a height of 10 feet. By how much does the height need to increase for the area to increase by 10.5 square feet? Write your answer as a decimal.
Area of a triangle = 1/2 x base x height
Area of original triangle = 1/2 x 7 x 10 = 35 square feet.
Add 1.5 feet to area to get 35 + 10.5 = 45.5 square feet.
Solve for the new height:
45.5 = 1/2 x 7 x H
Multiply both sides by 2:
91 = 7 x H
Divide both sides by 7:
H = 91/7
H = 13 feet
The new height needs to be 13 feet.
13 - 10 = 3 feet
The height has to increase by 3 feet.

Answer:
y=855/34 or 25 5/34
Step-by-step explanation:
Rewrite
5+y-5/34+3x7-6=45
Calculate Sum or differnce
5+y-5/34+21-6=45
Caculate difference
20+y-5/34=45
Move constant to the right
675/34+y=45
Caculate Difference
y=45-675/34
y=855/34 or you could put 25 5/34
Rick's cat weighs 7 pounds. His neighbor says her puppy weighs 103 ounces.
Does Rick's cat weigh more than the puppy?
1 pound = 16 ounces )
How much does Rick's cat weigh in ounces?
Answer:
1. Yes
2. 112 ounces
Step-by-step explanation:
To answer this question, we should first convert the amount of pounds Rick's cat weighs into ounces, so that both measurements are in the same unit. Since 1 pound is the same as 16 ounces, we can multiply 7 pounds by 16 ounces:
7 * 16 = 112
So, Rick's cat weighs 112 ounces, which is more than his neighbor's puppy, which only weighs 103 ounces. so for the first question, the answer is:
Yes, Rick's cat weighs more than the puppy.
And the second answer is:
Rick's cat weighs 112 ounces.

What does "area" mean in a circle?
Answer:
A = π(r)²
Step-by-step explanation:
The area of a circle is the inside of a circle. It can be found by multiplying pi by the radius raised to the power of 2 (squaring the radius).
Plot the following points on the coordinate plane. Connect them, and find the area of the shape that results.
(3,2) (-6,2) (-6,-8) (3,-8)
Answer:
The shape is a square and it's area is 121

The polynomial 2x³ + qx² + rx + 2 has a
factor (x - 1) and leaves a remainder of
12 when divided by (x - 2). Find the
constants q and r and hence the other
factors of the polynomial.
Answer:
q = 1 , r = -5
other factors of polynomial:
(2x - 1) & (x + 2)
Step-by-step explanation:
In the first part, substitute x = 1 make it equal to 0.
Substitute x = 2 and make it equal to 12.
Rearrange both, until you have two linear equations.
Solve the set of simultaneous equation to find q and r .
Second part place the value of q and r to have the full polynomial.
Carry out long division, dividing the polynomial by the factor that's stated in the question (x - 1) and you will have a quadratic equation.
Factorise the quadratic equation to have the two other factors of the polynomial.

what is the value of x , where
2x + 1 = 99
Answer:
x=49
Step-by-step explanation:
2x+1=99
2x=98
x=49
Answer:
To find the value of x we need to solve this equation
2x + 1 = 99
now ,taking constant to right side
2x = 99 - 1
2x = 98
x = 98/2
x= 49

Given right triangle ABC with altitude BD is drawn to hypotenuse AC. If AB=5 and AD=1, what is the length of AC ? (Note: the figure is not drawn to scale.)
Answer:
x = 24.99 or 25
Step-by-step explanation:
Using sin to figure out the angle of ABD, we can figure out the angle of CBD by subtracting it from 90°.
sin y = (1/5)
y = 11.54°
90 - 11.54 = 78.46°
Now using Pythagorean Theorem (a²+b²=c²) we can solve for line BD.
1² + b² = 5²
1 + b² = 25
b² = 24
b = √24
Now we can use tan to figure out the length of segment DC.
tan(78.46) = z/√24
z = 23.99
We can now combine the known length of segment AD and the length of DC to get x.
1 + 23.99 = 24.99 or about 25.
