Parker Peak 14,987.42
Snow Crest is 11,873.21 feet higher than Mt. Wilson. Write and solve an equation to find the elevation of Mt. Wilson. Let x represent the elevation of Mt. Wilson.
The equation to find the elevation of Mt. Wilson is - x =
The elevation of Mt. Wilson is feet.
Answers
Answer:
X = Y - 11873.21
X = 17009.1 feet
Step-by-step explanation:
Let x represent the elevation of Mt. Wilson. And
Y = Mt snow Crest.
Since Snow Crest is 11,873.21 feet higher than Mt. Wilson, the equation will be
X = Y - 11873.21
Where Y = 28,882.31
Substitute Y into the equation
X = 28882.31 - 11873.21
X = 17009.1 feet.

4/g=3.2
What is the letter g?
Answers
Answer:
g=1.25
Step-by-step explanation:
Divide 4 into 3.2
4/3.2=1.25
Try to use inverse operations to solve this problem.
First multiply both sides by g to get the g out from under the 4 The equation is now:
4=3.2g
From here then you divide both sides by 3.2.
The answer is g=1.25

A batter hits a fly ball. a scout in the stands makes the following observations. TIME (SECONDS) .75 1.5 2 2.75 3.25 4.75 HEIGHT (FEET) 77 133 160 187 194 169 What type of function that best models this data. use a graphing calculator to perform the regression for the best fit equation. write the resulting equation below, rounding to the nearest hundredth. determine the initial velocity of the baseball and the height of the ball when hit. round to the nearest hundredth. calculate how many seconds an outfielder has to position himself for the catch if he intends to catch the ball 6 feet above the ground. show your work and round to the nearest hundredth.
Answers
Answer:
y = -15.9x² + 110.48x + 3.02
initial velocity: 110.48 ft/s
initial height: 3.02 ft
time to cath the ball at 6 ft: 6.92
Step-by-step explanation:
In the picture attached, the plot of the data points and the equation of the best regression is shown, which correspond to a quadratic equation. (It was obtained using Excel)
The initial velocity is the second coefficient.
The initial height is the third coefficient.
Replacing y = 6 into the equation and solving with the quadratic formula:
6 = -15.9x² + 110.48x + 3.02
0 = -15.9x² + 110.48x + 3.02 - 6
0 = -15.9x² + 110.48x - 2.98
[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex]x = \frac{-110.48 \pm \sqrt{110.48^2 - 4(-15.9)(-2.98)}}{2(-15.9)} [/tex]
[tex]x = \frac{-110.48 \pm 109.62}{-31.8} [/tex]
[tex]x_1 = \frac{-110.48 + 109.62}{-31.8} [/tex]
[tex]x_1 = 0.03[/tex]
[tex]x_2 = \frac{-110.48 - 109.62}{-31.8} [/tex]
[tex]x_2 = 6.92[/tex]

Find the equation of the line that passes through the point (3,14) and is parallel to the following line y = 2/3x + 4
Answers
Answer:
y = 2/3x + 12
Step-by-step explanation:
Parallel means the same slope.
Using point-slope formula, you can find the new equation.
y-14 = 2/3 (x-3)
y-14 = 2/3x - 2
y = 2/3x + 12

Solve the following problem:
Given: △SAL, SA = LA
AT − ∠bisector
Prove: m∠L = m∠S
Answers
Answer:
[tex]\angle L=\angle S[/tex] using congruence rule
Step-by-step explanation:
Given: ΔSAL, SA = LA and AT is the bisector of [tex]\angle A[/tex]
To prove: [tex]\angle L=\angle S[/tex]
Proof:
Two triangles are congruent if they have same shape and same size.
Consider triangles ALT and AST
AL = AS
As AT bisects [tex]\angle A[/tex], [tex]\angle LAT=\angle SAT\\[/tex]
AT = AT (common side)
So, [tex]\Delta ALT\cong \Delta AST[/tex] ( by SAS congruence rule )
Here, SAS denotes side-angle-side
[tex]\angle L=\angle S[/tex] (using corresponding parts of congruent triangles)
Hence proved
Explanation:
First, we know that △ALT ≅ △AST, because of Side Angle Side Theorem. Next, we know that AL ≅ AS, because it's given.
Since A = A, we can remove A and it gives us m∠L = m∠S.
If you need to show work in math terms, your answer should look something like this:
1. △ ALT ≅ △AST - SAS
2. AL ≅ AS - Given
3. m∠ L ≅ m∠S

Answers
Answer:
$4785.68
Step-by-step explanation:
Original amount: $4230
Interest for 1 year: 4.2%
First year;
[tex]4230 + (4230 \times \frac{4.2}{100}) \\ = 4230 + 177.66 \\ = 4407.66[/tex]
Second year;
[tex]4407.66 + (4407.66 \times \frac{4.2}{100} ) \\ = 4407.66 + 185.12172 \\ = 4592.78172[/tex]
Third year (total balance after 3 years);
[tex]4592.78172 + (4592.78172 \times \frac{4.2}{100} ) \\ = 4592.78172 + 192.89683224 \\ =4785.67855224[/tex]
