The values are vx = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex], vw = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex] and m∠x = 45°, for the given right angle diagram.
Step-by-step explanation:
The given is,
Right angled triangle XVW,
XW = 14[tex]\sqrt{3}[/tex]
m∠V = 90°
m∠W = 45°
Step:1
Given diagram is right angle triangle,
Trigonometric ratios for right angle is,
[tex]sin[/tex] ∅ [tex]=\frac{Opp}{Hyp}[/tex]............................(1)
[tex]cos[/tex] ∅ [tex]= \frac{Adj}{Hyp}[/tex] .........................(2)
[tex]tan[/tex] ∅ [tex]= \frac{Opp}{Hyp}[/tex]..........................(3)
Step:2
For the value of VX,
[tex]sin[/tex] ∅ [tex]=\frac{VX}{XW}[/tex]
From given,
∅ = 45°
XW = 14[tex]\sqrt{3}[/tex]
Above equation becomes,
[tex]sin[/tex] 45 [tex]=\frac{VX}{14\sqrt{3} }[/tex]
Where, Sin 45 = [tex]\frac{1}{\sqrt{2} }[/tex],
[tex]\frac{1}{\sqrt{2} } = \frac{VX}{14\sqrt{3} }[/tex]
[tex]VX = \frac{14\sqrt{3} }{\sqrt{2} }[/tex]
Step:3
For the value of VW,
[tex]cos[/tex] ∅ [tex]=\frac{VW}{XW}[/tex]
From given,
∅ = 45°
XW = 14[tex]\sqrt{3}[/tex]
Above equation becomes,
[tex]cos[/tex] 45 [tex]=\frac{VW}{14\sqrt{3} }[/tex]
Where, cos 45 = [tex]\frac{1}{\sqrt{2} }[/tex],
[tex]\frac{1}{\sqrt{2} } = \frac{VW}{14\sqrt{3} }[/tex]
[tex]VW = \frac{14\sqrt{3} }{\sqrt{2} }[/tex]
Step:4
For the value m∠x = a,
[tex]tan[/tex] a [tex]=\frac{VX}{VW}[/tex]
From given,
VX = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex]
VW = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex]
Above equation becomes,
[tex]tan[/tex] a [tex]=\frac{\frac{14\sqrt{3} }{\sqrt{2} } } {\frac{14\sqrt{3} }{\sqrt{2} } }[/tex]
[tex]tan[/tex] a = 1
a = [tex]tan^{-1}[/tex] (1)
a = 45°
m∠x = a = 45°
Step:5
Check for solution,
m∠v = m∠w + m∠x
= 45° + 45°
90° = 90°
Result:
The values are vx = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex], vw = [tex]\frac{14\sqrt{3} }{\sqrt{2} }[/tex] and m∠x = 45°, for the given right angle diagram.

Write the explicit equation
for the sequence
9, 5, 1, -3, -7…
Answer:
13-4n
Step-by-step explanation:
The generic formula to calculate this is. a+(n-1) d
“a” is the first term and “d” is the difference in our case “a” is 9 and “d” is -4
9+(n-1)(-4)
9-4n+4
13-4n
Answer:
[tex]a_{n}[/tex] = 13 - 4n
Step-by-step explanation:
Note the common difference d between consecutive terms, that is
d = 5 - 9 = 1 - 5 = - 3 - 1 = - 7 - (- 3) = - 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 9 and d = - 4, thus
[tex]a_{n}[/tex] = 9 - 4(n - 1) = 9 - 4n + 4 = 13 - 4n ← explicit equation
One week, Huey worked 7 hours less than Dewey,
and Louie worked twice as long as Huey. Together
they worked 87 hours. Find the number of hours
worked by each.
Answer:
Number of hour worked by Dewey = 27 hours
Number of hour worked by Huey = 20hours
Number of hours worked by Louie = 40 hours
Step-by-step explanation:
Let x be number of hours worked by Dewey
Number of hour worked by Huey = x - 7
Number of hours worked by Louie = 2*(x-7) = 2*x -2*7 = 2x- 14
Together they worked 87 hours
x + x-7 + 2x-14 = 87
4x - 21 = 87
4x = 87 +21
4x = 108
x = 108/4
x = 27 hours
Number of hour worked by Dewey = 27 hours
Number of hour worked by Huey = x - 7 = 27 - 7 = 20hours
Number of hours worked by Louie = 2x - 14 = 2*27 - 14 = 54 - 14 = 40 hours

1. Find the height of a cylinder with a volume of 30 in) and a radius of 1 in.
Answer:
9.55
Step-by-step explanation:
with a radius of 1 and a volume of 30 the height should be around 9.55
The height of the cylinder is 9.549 in with a volume of 30 cubics in and a radius of 1 in.
It is given that the volume of a cylinder is 30 cubic in and the radius is 1 in.
It is required to find the height of the cylinder.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of a cylinder:
[tex]\rm V = \pi r^2 h[/tex]
Where r is the radius of a cylinder and h is the height of the cylinder.
Here V = 30 cubic in and r = 1 in
[tex]\rm 30 = \pi\times 1^2\times h[/tex] or
πh = 30
h = 9.549 in
Thus, the height of the cylinder is 9.549 in with a volume of 30 cubics in and a radius of 1 in.

A circle in the xy-plane has its center at (-2/3,-3/4)
and radius 5. Which of the following is an
equation of the circle?
Answer:
(x + 2/3)^2 + (y + 3/4)^2 = 5^2
Step-by-step explanation:
Apply the general formula for a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius. Since the center is (-2/3, -3/4), and r = 5, we get:
(x + 2/3)^2 + (y + 3/4)^2 = 5^2
Principal = $800
Interest Rate = 3.5%
Time = 6 months
Find the interest earnedi
The interest earned is $14.
To find the interest earned, we can use the formula for simple interest:
[tex]\[ \text{Simple Interest} = \frac{P \times R \times T}{100} \][/tex]
Where:
- [tex]\( P \)[/tex]is the principal amount (the initial amount of money) [tex]= $800[/tex]
-[tex]\( R \)[/tex]is the interest rate per period (in decimal form) [tex]= 3.5% = 0.035[/tex]
-[tex]\( T \)[/tex] is the time the money is invested for (in years)[tex]= 6 months = 0.5 years[/tex]
Now, plug in the values:
[tex]\[ \text{Simple Interest} = \frac{800 \times 3.5 \times 0.5}{100} \][/tex]
[tex]\[ \text{Simple Interest} = \frac{800 \times 3.5 \times 0.5}{100} \][/tex]
[tex]\[ \text{Simple Interest} = \frac{800 \times 1.75}{100} \][/tex]
[tex]\[ \text{Simple Interest} = \frac{1400}{100} \][/tex]
[tex]\[ \text{Simple Interest} = \[14 \][/tex]
Complete correct question:
Principal = $800
Interest Rate = 3.5%
Time = 6 months

David has 56 baseball card I wish he sells three cars per week write an equation representing the number of cards n he has left at the end of any given week W
Answer:
56-3=N
Step-by-step explanation:
David starts with 56 baseball cards and sells 3 per week, so the equation representing the cards remaining after W weeks is n = 56 - 3W.
The equation that represents the number of baseball cards David has left at the end of any given week W is n = 56 - 3W. Here, 'n' stands for the number of cards he has left, '56' is the initial number of cards, '3' is the number of cards he sells each week, and 'W' is the number of weeks that have passed.
For example, at the end of week 1 (when W = 1), David will have:
n = 56 - 3(1) = 56 - 3 = 53 cards left.
At the end of week 2 (when W = 2), it would be:
n = 56 - 3(2) = 56 - 6 = 50 cards remaining.
This pattern continues as more weeks pass.
Based on the scale drawing, what is the length, in feet, of the actual parking lot? On the drawing they have the width 12.8 cm and the length is 3.2 cm.
Answer:
The width of 48 feet is represented by 12.8cm; the length represented by 1cm is 48/12.8 = 15/4 = 3.75 feet.
The length on the drawing is 3.2cm, which is exactly 1/4 of the width of 12.8cm; therefore the length of the actual parking lot is 48/4 = 12 feet.
To find the actual length of a parking lot based on a scale drawing, you need the scale, which is often given as a ratio like '1 cm : 10 ft'. You would multiply the length on the drawing by the scale value to get the actual length. However, without the scale, a definitive answer cannot be provided.
Explanation:To find the actual length of the parking lot, you need to know the scale of the drawing, which is not provided in the current question. The scale is usually expressed as a ratio, essentially representing a conversion factor. An example could be '1 cm : 10 ft', meaning every one centimeter on the drawing represents ten feet in real life.
Let's say the scale is '1 cm : 10 ft' as an example. You would then multiply the scale value (10 ft) by the length of the parking lot on the drawing (3.2 cm). So: 3.2 cm * 10 ft/cm = 32 ft. Hence, in this example, the actual length of the parking lot would be 32 feet. However, without the scale, we cannot provide a definitive answer.

Alex has trained his puppy, Popper, to jump through a ring. According to Alex's measurements and calculations, the ring has a diameter of 3.5 feet. What is the ring's circumference (use 3.14 for pi)?
Answer:
11 ft
Step-by-step explanation:
The ring takes circular shape and for a circle, circumference is given by
[tex]C=\pi d[/tex]
Where C represent circumference and d is the diameter.
Taking use 3.14 for pi as instructed and substituting 3.5 ft for diameter d then
C=3.14*3.5=10.99 ft
Rounding off, this is approximately 11 ft
Answer:
10.99 ft
Step-by-step explanation:
Given: The ring has a diameter of 3.5 feet
To find: The ring's circumference
Formula: [tex]C = 2\pi r[/tex]
Solution: To calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2 × radius with pi (π = 3.14).
C = pi × 2r
C = pi × diameter (3.5)
C = 3.14 × 3.5 = 10.99
Hence, the ring's circumference is 10.99 ft
