Answer:
Max height = 128feet
Time = 0secs
Step-by-step explanation:
Given the height in ft of a rocket after x seconds is given by y=128-16x^2, at maximum height, the velocity of the object is zero that is;
dy/dx = 0
0 - 32x = 0
x = 0/-32
x = 0
Hence the time taken for the object to reach its maximum height is 0 secs
To get the maximum height reached, you will substitute x = 0 into th expression given as shown;
y = 128 - 16x^2
y = 128 - 16(0)^2
y = 128 - 0
y = 128feet
Hence the maximum height reached by the rocket is 128feet

Answer:
a = 120
b = 120
y = 22
a and b and vertical angles
Step-by-step explanation:
angles A and B are vertical angles so they're equal.
you can find angle b because all the angles in a triangle add up to 180
19 + 41 + B = 180
b = 180 - 19 - 41
b = 120
and since theyre equal, that means
a = 120 as well.
since you know a = 120 you can find y.
120 + 38 + y = 180
y = 180 - 120 - 38
y = 22

PLS HELP!!! TIMED!!!! I need a step by step explanation of how to divide 93726 by 4!!!!
Answer: the answer is 23434
Step-by-step explanation:first divide 4 by 9 which goes only once, then you would then have 13 which would go only 3 times so 12 minus 13 which is 1 and then goes with 7 to make 17 which means it goes in only 4 times which is 16 meaning the answer is 1 again and then goes with 3 to make 13 and 4 goes in 3 times with 13 to make 12 and then you get 1 which goes into 6 to make 16 and then 4 goes into 16 4 times and then you would get an answer of 23434

A man saves 8% of his salary every mon. If he saves 288
month, what is his salary?
Answer:
New monthly salary: $264.96
Step-by-step explanation:
you would first change your percent into a decimal.
our given percent is 8% = 0.08
then after that multiple by the original principal
288 x 0.08
this equation will give you 23.04
next you would then have to subtract the given product from by the original principal once again.
288-23.04
this equation will then give you your sum of $264.96
as his new monthly salary.
Which number best represents a depth of seven hundred and five-tenths meters below the ground?
Answer:
-700½ meters or -700.5 meters
Step-by-step explanation:
Usually, the depths below the ground are denoted by the minus sign.
Seven hundred and five-tenths meters mean 700+(5/10) which is equal to 700+1/2. So, the answer becomes -700½ meters or -700.5 meters.

one of the acute angles in a right triangle has a measure of 34.6 degrees. What is the measure of the other acute angle
Answer:
55.4
Step-by-step explanation:
The sum of the angles of a triangle is 180
If we have a right triangle, one angle is 90
The other two angles must add to 90 degrees
Let the unknown angle be x
34.6 + x = 90
Subtract 34.6 from each side
34.6+x-34.6 = 90-34.6
x =55.4

3. ALGEBRA Nancy Boone's new automobile had an MSRP of
$27,853.00. The dealer prep charge was $278.50 and the title ſee
was $25.00. Options totaled $2,375,50. Find the sales tax rate,
to nearest hundredth percent iſ the total cost was $32 591.22
and the sales tax applied to everything but the title fee.
Answer:
The tax rate is approximately 6.75%
Step-by-step explanation:
In the question it is required to find the amount added to the total cost as tax
The given parameters are;
The Manufacturer's Suggested Retail Price, MSRP, of the automobile, MSRP = $27,853.00
The dealer prep charge, PPC = $278.50
The title fee, T = $25.00
The cost of the options added (leather, fridge, etc.), Op = $2,375.50
The total cost, C = $32,591.22
Let 'x' represent the the tax rate,
Therefore, we have;
32,591.22 = x × (27,853 + 278 + 2,375.5) + 27,853 + 278 + 2,375.5 + 25
32,591.22 = 30,506.5·x + 30,531.5
32,591.22 - 30,531.5 = 30,506.5·x
∴ 2,059.72 = 30,506.5·x
x = 2,059.72/30,506.5 = 0.06751741432 ≈ 0.0675
The tax rate, x ≈ 0.0675 = 6.75%

I will Mark Brainliest
The answer is NOT 54.97
Don't forget to convert the percent into a decimal.
Answer:
Amount of tax = 26.93 (Approx.)
Step-by-step explanation:
Given:
Cost of computer = $398.50
Sales tax rate = 7.25% = 0.0725
Find:
Amount of tax
Computation:
Amount of tax = [Cost of computer x Sales tax rate] / [1+Sales tax rate]
Amount of tax = [398.50 x 0.0725] / [1+0.0725]
Amount of tax = 26.93 (Approx.)

Find the tangent of angle U.
A) 48/55
B) 48/73
C) 55/48
D) 55/73
Answer:
C. 55/48
Step-by-step explanation:
perpendicular (p) = 55
base (b) = 48
Tangent < U = p /b = 55 /48
In triangle TUV, the tangent of angle U would be tan U = 55/58. Hence option C is true.
Used the formula of the tangent of an angle that states,
Tan θ = Opposite / Base
Given that,
A triangle TUV is shown in the image.
Now by definition of the tangent of an angle,
tan U = TV/UV
Substitute TV = 55 , UV = 48;
tan U = 55/58
Therefore, Option C is true.
