Gary's parents want him to attend The University of Houston. They opened a college savings account 15 years ago. Today, average yearly tuition and fees for one year at the university are about $10,350. Based on this information, about how much should Gary's parents have saved each of the 15 years to cover the cost of 4 years at The University of Houston?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Today, average yearly tuition and fees for one year at the university are about $10,350.
I will assume a yearly interest rate of 8%.
First, we need to calculate the total amount needed:
Future value (FV)= 10,350*4= $41,400
Now, using the following formula, the annual deposit required:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (41,400*0.08) / [(1.08^15) - 1]
A= $7,194.22

Form and solve an equation for .
5x - 7
23
Answer:
x = 6
Step-by-step explanation:
5x - 7 and 23 are vertical angles and are congruent , then
5x - 7 = 23 ( add 7 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6

A lamp produced a shadow of a man standing in the middle of a stage.
21° 19°
25 meters
How long is the shadow?
;
Answer: 11.38
Step-by-step explanation:
I just did this math nation question and that’s what they said the answer was
The solution is, Length of the shadow = 11.4 m.
What are trigonometric relations?Trigonometry can be stated as the study of the relationships between the angles and the lengths of the sides of triangles.
here, we have,
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
here, we have,
Given the graph:
The length of the shadow = y - x.
• To find x:
tan 21 = x/25
so, we get,
x = 25 * tan 21
=9.6m
• To find y:
tan 40 = y/25
so, we get,
y = 25* tan40
= 21m
Length of the shadow:
length = 21 - 9.6 m
= 11.4m
so, we get,
Length of the shadow = 11.4 m

Round each fraction to the nearest half and find the estimate. 2/6 + 1/6 one half 1 one and one half 2
Answer:
one half
Step-by-step explanation:
Given the expression
2/6 + 1/6
Find the LCM
[tex]= \dfrac{2+1}{6} \\= \dfrac{3}{6} \\= \dfrac{3*1}{3*2}\\= \dfrac{3}{3} * \dfrac{1}{2} \\= 1 * \dfrac{1}{2}\\= \dfrac{1}{2}[/tex]
Hence the required result is one half

What is the length of JK¯¯¯¯¯, to the nearest tenth of a millimeter? 4.5 mm 5.6 mm 8.3 mm 19.9 mm A horizontally-aligned scalene triangle J K L. Side J L is labeled as 3 millimeters. Side L K is labeled as 5 millimeters. Angle L is labeled as 62 degrees.
Answer:
5 = side a
3 = side c
angle B = 62 degrees
JK is side b
Use the Law of Cosines to find the length of side b.
b^2 = a^2 + c^2 − 2ac cos(B)
b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)
b^2 = (25 + 9) − 30 x 0.469
b^2 = 34 - 30 x 0.469
b^2 = 34 - 14.084
b^2 = 19.916
b = √19.916
b = 4.463
Rounded to the nearest tenth is 4.5 mm.
