Answer:
66 feet
Step-by-step explanation:
We know that the t in the equation represents the time. So, substitute 2 for the t in the function and simplify to find the height after 2 seconds:
[tex]h(t) = -16t^2+63t+4\\h(2) = -16(2)^2+63(2)+4\\h(2) = -16(4)+126+4\\h(2) = -64 + 126+4\\h(2) = 66[/tex]
Thus, the height would be 66 feet.
The ratio of the number of fiction books to the number of non-fiction books in a library is 8:5. There are 678 more fiction books than non-fiction books. How many non-fiction books are there in the library?
Answer:
1130 non fiction
Step-by-step explanation:
F=fiction
NF=non fiction
F-678=NF
5F=8NF
so NF=5/8F
substitute:
F-678=5/8F
reduce:
3/8F=678
F=1808
NF=1130
There are 1130 non fiction books in the library.
Given that,
Ratio of fiction books (F) to non fiction books (NF) is 8:5.678 more fiction books in library.We need to find the number of non fiction books.According to the scenario, calculation of data are as follows,
[tex]\frac{F}{NF} = \frac{8}{5}[/tex]
or 5F = 8NF
Now, NF = F-678
By putting the value, we get
5F = 8 ( F - 678)
5F = 8F - 5424
3F = 5424
F = 1808
So, By putting in 1st eq. we get,
5 [tex]\times[/tex] 1808 = 8NF
NF = 9040 [tex]\div[/tex] 8
NF = 1130
Non fiction books = 1130 books.

What is the area of this quadrilateral?
8 ft
6 ft
3.ft
A. 33 square feet
B. 42 square feet
C. 17 square feet
D. 66 square feet
Answer:
a. 33 sqft
Step-by-step explanation:
The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles
Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)
The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24
The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9
Total area is sum of these two or 24 + 9 = 33
Mason used a 30% coupon to buy a new computer. After the discount, the cost of the computer was 728. Determine the original price of the computer. Calculate how much money mason saved by using the coupon.
Answer:
Mason saved $312.00.
Step-by-step explanation:
This is because, if you multiply the original price by 30%/100 or $1040 x 0.3 you get $312.00. So basically, multiply the original price by the discount number over 100 you get your answer.
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
The original price of the computer is 1040.
The amount saved by Mason using the coupon is 312.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Coupon = 30% off
Cost of the computer after the coupon = 728
This means that the cost of the computer is only 70% since 30% is off.
70% = 728
We know that the original price is 100%.
So,
70% = 728
Multiply 100/70 on both sides.
100/70 x 70% = 100/70 x 728
100% = 1040
The original price of the computer is 1040
The amount saved is:
= 1040 - 728
= 312
Thus,
The original price of the computer is 1040.
The amount saved by Mason using the coupon is 312.

Let X=X=X, equals the number of answers Philip correctly guesses in the last 444 questions. Assume that the results of his guesses are independent.
The probability that Philip answers exactly one question correctly in the last 4 questions is 0.4096.
How to calculate the probability?Probability simply means the chance that a particular thing or event will happen. It is the occurence of likely events. It is simply the area of mathematics that deals with the numerical estimates of the chance that an event will occur
It should be noted that this relates to a binomial probability. This is Illustrated as:
n! / x! (n - x)!
n = number if questions = 4
The probability will be:
P(x = 1) = (0.2)¹ × 0.8³.
