A guy wire runs from the top of a cell tower to a metal stake in the ground. Lincoln places a 10-foot tall pole to support the guy wire. After placing the pole, Lincoln measures the distance from the stake to the pole to be 5 ft. He then measures the distance from the pole to the tower to be 14 ft. Find the length of the guy wire, to the nearest foot.
Step-by-step explanation:
2 right triangles are formed.
x is the angle btw wire and grnd
tan x = 10/5 = 2
tanx = ht of tower/(5+14)
2 = tower ht/19
tower ht = 38
length of wire =
[tex] \sqrt{ {38}^{2} + {19}^{2} } [/tex]

Louise begins factoring the polynomial, which has four terms. 8x3 24x2 10x 30 2(4x3 12x2 5x 15) 2[4x2(x 3) 5(x 3)] Which is the completely factored form of her polynomial? 8x2(x 3)2 2x(4x2 5) 2(4x2 5) (x 3) 2(4x2 5) (x 3)2.
A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.
The completely factored form of Louise polynomial equation is,
[tex]2[(4x^2+5)(x +3) ][/tex]
Thus the option 3 is the correct option.
What is polynomial equation?A polynomial equation is the equation in which the unknown variable is one and the highest power of the unknown variable is n.
Here, n is any real number.
Given information-
The given polynomial equation in the problem is,
[tex]8x^3 +24x^2 +10x+ 30[/tex]
The given polynomial has the highest power of variable is three. Thus it is a trinomial equation.
Louise then took out the common number 2 from the equation as,
[tex]2[4x^3 +12x^2 +5x+ 15][/tex]
In the third step took out the common number to make the groups as,
[tex]2[4x^2(x +3) +5(x+ 3)][/tex]
Simplify the equation further to get the factors,

Solve the system of linear equations by substitution.
3x - 2y = 11
x + 2y = 9
The solution of the system is
Answer:
x=5, y=2
Step-by-step explanation:
1) Subtract 2y from both sides of x+2y to get x=9-2y
2) Substitute x into the first equation to get 3(9-2y)-2y=11
3) Solve for y (y=2)
4) Plug y into either equation: x+2(2)=9 x=5
5) The answer is (5, 2)

I will attach a screenshot of the math problem.
Complete the table for the function y = 0.1^x
The first step: plug values from the left column into the ‘x’ spot in the formula y=0.1^x.
* 0.1^-2 : We can eliminate the negative exponent value by using the rule a^-1 = 1/a. Keep this rule in mind for future problems. (0.1^-2 = 1/0.1 * 0.1 = 100).
* 0.1^-1 = 1/0.1 = 10
* 0.1^0 = 1 : (Remember this rule: a^0 = 1)
* 0.1^1 = 0.1
Our list of values: 100, 10, 1, 0.1
Now, we can plug these values into your table:
[tex]\left[\begin{array}{ccc}x&y\\2&10\\1&10\\0&1\\1&0.1\end{array}\right][/tex]
The points can now be graphed. I will paste a Desmos screenshot; try to see if you can find some of the indicated (x,y) values: [screenshot is attached]

Because
2×3²×5 =90
And
2×3×3×5 =90
Answer:
A; 2 * 3^2 * 5
Step-by-step explanation:
Factorization is when you multiply numbers to the lowest form
so to get 90 you can do
45 * 2 = 90
9 * 5 = 45
3 * 3 = 9
2 * 3 * 3 * 5 = 90

On an application form, Mary needs to put her daughter's age in months. If her daughter is 4 2/3 old, what number should Mary put on the form?
Answer:
56 months
Step-by-step explanation:
1 year= 12 months
4 years=12x4= 48 months
2/3 years=8 months
number she should put=48+8=56 months
Answer:
56 months
Step-by-step explanation:
4 2/3 years
= 4 years and 2/3 of a year
remember, 12 months = 1year
so, 2/3 of 1 year = 2/3 of 12 months
= 2/3 × 12
= 8 months.
For 4 years to months,
4 × 12 months = 48 months
so, 4 2/3 years = 48 + 8
56months

Darnell buys homes and flips them by completing renovations to turn a profit on his investment. He is currently working on a house with three bedrooms that need new hardwood floors. He is estimating the total cost to purchase hardwood flooring for the bedrooms with the following dimensions.
Bedroom 1: 22 feet by 15 feet
Bedroom 2: 15 feet by 12 feet
Bedroom 3: 13 feet by 12 feet
A big home improvement store advertises the price of two types of flooring, shown below.
$7.25 per square foot
$6.75 per square foot plus a $100 fixed installation fee
Which of these two prices would be best for Darnell to estimate the total cost of new hardwood flooring in the three bedrooms?
Answer:
Look below for answer! Have a great day and please mark me brainliest!
Step-by-step explanation:
Bedroom 1: 22x15=330
330x7.25=2392.5
Bedroom 2: 15x12=180
180x7.25=1305
Bedroom 3: 13x12=156
156x7.25=1131
2392.5+1305+1131= 4828.5
Bedroom 1: 22x15=330
330x6.75=2227.5
Bedroom 2: 15x12=180
180x6.75=1215
Bedroom 3: 13x12=156
156x6.75=1053
2227.5+1215+1053+100= 4595.5
Therefore, 6.75 per square foot plus a $100 fixed installation fee would be the cheapest.

Identify the function shown in this graph
Answer:
C. y = 2x - 3
Step-by-step explanation:
Let's go through process of elimination!
First, we can see that the line intersects the y-axis at (0,-3), making the y-intercept -3. In the equation y = mx + b, b is the y-intercept. Therefore, we can easily take out A and D as the wrong answers because their b isn't -3.
Next, we should know that a line with a positive slope is going up, and this line, indeed, is going up. B can't be right because the slope is negative, meaning the line would go down. That leaves us with answer C as the correct choice.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Zeros of quadratc equationGiven the function g(x)=−x^2+x+20
Factorize the expression
g(x) = -x^2 +5x - 4x + 20
g(x) = -x(x-5)-4(x-5)
g(x) = (-x-4)(x-5)
Equating the result to zero
x - 5 = 0
x = 5
Similarly, -x-4 = 0
