Step-by-step explanation:
A dolphin jumps from the water at an initial velocity of 16 feet per second. The equation h + -16t^2 + 80t models the dolphin's height at any given time, t. What is the maximum height the dolphin jumps?
Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence the maximum height the dolphin jumps is 100feet

The length of a rectangle is five more than three time its width. The perimeter of a rectangle is 234. What is the width of the rectangle
Answer:
28 units
Step-by-step explanation:
Given data
Let the width be x
The length is =3x+5
Perimeeter= 234
The expression for the perimeter is
P=2L+2W
Substitute
234= 2*x+2(3x+5)
234= 2x+6x+10
Collect like terms
234= 8x+10
234-10= 8x
224=8x
x= 224/8
x=28
Hence the width is 28 units

Find the LCM and HCF of 64 and 72 using prime factors
What is the LCM of 64 and 72?
Find the prime factorization of 64.
Find the prime factorization of 72. 72 = 2 × 2 × 2 × 3 × 3.
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM: LCM = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3.
LCM = 576.
What is the GCF of 64 and 72?
Find the prime factorization of 64. 64 = 2 × 2 × 2 × 2 × 2 × 2.
Find the prime factorization of 72. 72 = 2 × 2 × 2 × 3 × 3.
To find the GCF, multiply all the prime factors common to both numbers: Therefore, GCF = 2 × 2 × 2.
GCF = 8.
Answer:

A triangle has sides with lengths of 26 yards, 76 yards, and 78 yards. Is it a right triangle?
Options:
Yes
No
Answer:
No
Step-by-step explanation:
a^2 + b^2 = c^2
Since 78 is the largest it will be c.
26^2 + 76^2 = 78^2
676 + 5776 = 6084
6452 does NOT = 6084
Since c^2 is larger it is an obtuse triangle.
From Monday through Friday, works in the on and in the on another . On Saturday and Sunday, 50% of the days. How many days does work in a week? What percent of Monday through Friday does work?
Complete question :
From Monday through Friday, James works in the library on 2 days and in the cafeteria on another day. On Saturday and Sunday, James washes cars 50% of the days. How many days does James work in a week? What percent of the days from Monday through Friday does he work?
Answer:
4 days ;
60%
Step-by-step explanation:
From Monday to Friday
Number of days in library = 2
Number of days in cafeteria = 1
50% of days in weekends
Number of weekend days = 2
50% of 2 = 0.5 * 2 = 1 day
Total. Number of days worked = (2 +1 + 1) = 4 days
What percent of the days from Monday through Friday does he work?
Number of days workwd from. Monday to Friday = 3
Total number of days from Monday to Friday = 5
Percentage of days worked from Monday to Friday
= number of days worked / total number of days
= 3 /5 * 100%
= 0.6 * 100%
= 60%

In a large population, 92% of the households have cable tv. A simple random sample of 225 households is to be contacted and the sample proportion computed. What is the mean and standard deviation of the sampling distribution of the sample proportions
Answer:
the mean and the standard deviation is 0.92 and 0.01808 respectively
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
The mean is 0.92
And, the standard deviation is
= √0.92 × (1 - 0.92) ÷ √225
= √0.92 × 0.08 ÷ √225
= √0.0736 ÷ √225
= √3.27
= 0.01808
Hence, the mean and the standard deviation is 0.92 and 0.01808 respectively

Voting in Seaside's annual school board elections has been going down by 10% from one election to the next. If 990 parents voted this year, how many will vote 4 years from now?
If necessary, round your answer to the nearest whole number.
Answer:
FV= 676
Step-by-step explanation:
Giving the following formula:
Present value (PV)= 990 parents
Decrease rate (d)= 10% = 0.1 per year
Number of periods (n)= 4
To calculate the future value of votes, we need to use the following formula:
FV= PV / (1 + d)^n
FV= 990 / (1.1^4)
FV= 676

If money in a savings account earned 8% interest per annum, how much nterest would be earned on $150.00 over three years?
Answer:
$36
Step-by-step explanation:
Given :
Interest rate, r = 8% = 0.08

9514 1404 393
Answer:
(d) (-3, 1)
Step-by-step explanation:
We assume a typo in the problem statement, and that the equations are supposed to be ...
[tex]2x -3y = -9\\-x +3y = 6[/tex]
Adding the two equations gives ...
x = -3
Substituting for x in the second equation gives ...
3 +3y = 6
1 + y = 2 . . . . divide by 3
y = 1 . . . . . . . subtract 1
The solution is (x, y) = (-3, 1).
