Answer:
10.5618feet, 0.8125sec
Step-by-step explanation:
Given the height reached by the catapult expressed by the equation H=-16T^2+26T
At the maximum height, the velocity of the object is zero, hence;
v = dh/dt = 0
-32t + 26 = 0
-32t = -26
t = 26/32
t = 0.8125secs
Hence it will attain the maximum height after 0.8125second
Substitute t = 0.8125s into the expression to get the maximum height
H=-16t^2+26t
H = -16(0.8125)^2 + 26(0.8125)
H = -16(0.6602) + 21.125
H = -10.5632+21.125
H = 10.5618
hence the maximum height reached by the ball is 10.5618feet

A student simplified the expression (3x^2+2)-(2x^2+4) as x^2+^6 Explain what the student did incorrectly and state the correct answer.
Answer:
x^2 - 2
Step-by-step explanation:
The correct procedure would have been to distribute the negative to the +4 also, so you would have +2 - 4 = -2 so the final answer should have been
x^2 - 2
(3x²+2)-(2x²+4)
write in a different form, remove parentheses
3x²+2-2x²-4
calculate the value of the corresponding terms
x²-2
Answer: Yes, he made a mistake.
A simplified expression would look like this x²-2 and not like this x²+^6.

Answer:
-8n² - 8n + 3
Step-by-step explanation:
Combine like terms (terms with the same variables, as well as the same amount of that variable).
(4n⁴ - 8n + 4) - (8n² + 4n⁴ + 1)
First, distribute the negative sign to all terms within the second parenthesis:
4n⁴ - 8n + 4 - 8n² - 4n⁴ - 1
Combine like terms:
(4n⁴ - 4n⁴) - 8n² - 8n + (4 - 1)
-8n² - 8n + 3
-8n² - 8n + 3 is your answer.

Answer:
arc WVY = 250°
Step-by-step explanation:
The tangent- tangent angle YXW is half the difference of the intercepted arcs
[tex]\frac{1}{2}[/tex] ( WVY - WY) = 70
[tex]\frac{1}{2}[/tex] (10a - (4a + 10) ) = 70 ( multiply both sides by 2 )
10a - 4a - 10 = 140
6a - 10 = 140 ( add 10 to both sides )
6a = 150 ( divide both sides by 6 )
a = 25
Then
arc WVY = 10x = 10 × 25 = 250°
Sally works for 38 hours per week. Her weekly wage is £355.68
She receives a pay increase of 23p per hour.
Work out her new weekly wage.
Answer:
£364.42
Step-by-step explanation:
£355.68 ÷ 38 hours = £9.36 per hour
£9.36 + £0.23 = £9.59 per hour
£9.59 * 38 = £364.42
Find the slope of the line that contains the I
point (4, -9) and has a y intercept of 2.
Answer:
-11/4
Step-by-step explanation:
The y intercept has the coordinates of (0,2)
We have two points (0,2) and (4,-9) so we can find the slope using
m= (y2-y1)/(x2-x1)
= ( -9-2)/(4-0)
= -11/4
Answer:
-11/4
Step-by-step explanation:
y = mx + c
Point (x,y)
intercept c
slope m
-9 = m(4) + 2
-9 = 4m + 2
make m the subject of the formula
4m = -9-2
4m = -11
divide both sides by 4
m = -11/4

In the sequence: 20, 25, 23, 28, 26, …, what number should come next?
a) 24
b) 31
c) 21
d) 28
Answer:
b) 31
Step-by-step explanation:
20 + 5 = 25
25 - 2 = 23
23 + 5 =28
28 - 2 = 26
pattern: add 5 then subtract 2
since we subtract last, we would add 5 on 26:
26 + 5 = 31
Answer:
31
Step-by-step explanation:
In the sequence they are adding 5 and taking away 2. So if they start with 20, they added 5 and took away 2, it was 23. Then they added 5 again and it was 28, they took away 2 and it was 26. If they add 5, the next number would be 31.

James, Reed, Spencer and Larry have 912 cups of trail mix for their hike. If they each eat the same amount of trail mix, how many cups will each person eat?
Answer:
228 cups
Step-by-step explanation:
the cups each person will eat can be found by dividing the total number of trail by the number of people who went on the hike
total number of people on the hike = 4
total cups of trail = 912
912 / 4 = 228 cups

F(x) = x^2 -7x +14, g(x) = 4x -9
Find (g ° f)(x)
Answer:
Set up the composite result function.
g(F(x)) Evaluate g(x2−7x+14)
by substituting in the value of F into g.
g(x2−7x+14)=4(x2−7x+14)−9
Simplify each term.
g(x2−7x+14)=4x2−28x+56−9
Subtract 9 from 56.
g(x2−7x+14)=4x2−28x+47

the hotog eating champion eats 27.5 hot dogs in 4 minutes. at that rate how many does he eat in the 10 min competition?
Answer:
68.8 hot dogs
Step-by-step explanation:
27.5 ÷ 4 = 6.875 per minute
6.875x10 = 68.75 hot dogs
Answer:
68.75 hotdogs
Step-by-step explanation:
lets say x = number of hotdogs
27.5/4 = x/10
use cross multiplication:
27.5 (10) = 4(x)
multiply
275 = 4x
divide both sides by 4 to isolate x
x = 68.75

The hypotenuse of a right triangle measures 19 cm and one of its legs measures 2 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer:
cm
Submit Answer
attempt 1 out of 2
Answer:
18.9 cm
Step-by-step explanation:
Pythagorean Theorem --> A² + B² = C²
2² + B² = 19²
4 + B² = 361
B² = 357
√357 --> 18.89 --> 18.9
The measure of the other leg to the nearest tenth will be 18.9 centimeters.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
The hypotenuse of a right triangle measures 19 cm and one of its legs measures 2 cm.
Let the other leg be 'x'. Then the measure of the other leg will be given as,
19² = x² + 2²
361 = x² + 4
x² = 361 - 4
x² = 357
Take square root on both sides, then we have
x = √357
x = 18.8944
x ≈ 18.9 cm
The measure of the other leg to the nearest tenth will be 18.9 centimeters.

there are five marbles in a bag. three are green and two are yellow. you draw a marble, replace it, and then draw another. what is the probability of choosing a green marble and then a yellow marble.
Answer: 1/10
Step-by-step explanation:
1: Let’s take out the “DO NOT REPLACE IT.” It can make the whole thing seem harder. Rather, here is this. “There are five marbles in a bag, 3/5 are green and 2/5 are yellow. You DRAW TWO MARBLES. What is the chance of you drawing two yellow marbles?”
2 : Now let’s look at some important information.
100% of marbles= 5 marbles.
60% of marbles= the three green marbles.
40% of marbles= the two yellow ones.
Picking 2 of the 5 marbles will mean taking 40% of the marbles out of the bag.
Simplify: Now, to make it easier, the question is this. what is the chances of the 40% being the same color, Specifically yellow.
3: Let me explain. There are two yellow marbles, you pick out two. That is a one out of five chance of you getting ONE yellow marble the first time. That is 1/5. picking two at the same time results in a 2/5 chance.
4: if you pick twice it would be 1/10 chance.
