Answer:
if the ladder is 12 ft., and the bottom of the ladder is 6 feet away from the wall, the top of the ladder, instead of being on the 12 foot mark on the wall, would slide down 6 feet because the farther away from the wall the bottom on the ladder is the more the top of the ladder slides down because the ladder doesn't change its length in the triangle.
Step-by-step explanation:
12 - 6 = 6
[tex]f(x)=|3x-5|+7x\\g(x)=-2x+9\\what is \\ (f+g)(x)[/tex]
Given:
The functions are:
[tex]f(x)=|3x-5|+7x[/tex]
[tex]g(x)=-2x+9[/tex]
To find:
The function [tex](f+g)(x)[/tex].
Solution:
We have,
[tex]f(x)=|3x-5|+7x[/tex]
[tex]g(x)=-2x+9[/tex]
We know that,
[tex](f+g)(x)=f(x)+g(x)[/tex]
On substituting the values of given functions, we get
[tex](f+g)(x)=|3x-5|+7x+(-2x+9)[/tex]
[tex](f+g)(x)=|3x-5|+7x-2x+9[/tex]
[tex](f+g)(x)=|3x-5|+5x+9[/tex]
Therefore, the required function is [tex](f+g)(x)=|3x-5|+5x+9[/tex].

f a1 = 7 and an = 5an-1 then find the value of a6
Answer:
a₆ = 21875
Step-by-step explanation:
Using the recursive rule and a₁ = 7 , then
a₂ = 5a₁ = 5 × 7 = 35
a₃ - 5a₂ = 5 × 35 = 175
a₄ = 5a₃ = 5 × 175 = 875
a₅ = 5a₄ = 5 × 875 = 4375
a₆ = 5a₅ = 5 × 4375 = 21875

A radio signal travels at 3. 00 10 8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3. 54 10 7 meters? Show your work.
Answer:
[tex]0.1157\ \text{s}[/tex]
Step-by-step explanation:
[tex]v[/tex] = Velocity of radio signal = [tex]3\times 10^8\ \text{m/s}[/tex]
[tex]d[/tex] = Distance = [tex]3.47\times 10^7\ \text{m}[/tex]
Time is given by
[tex]t=\dfrac{d}{v}[/tex]
[tex]\Rightarrow t=\dfrac{3.47\times 10^7}{3\times 10^8}[/tex]
[tex]\Rightarrow t=0.1157\ \text{s}[/tex]
Time taken by a signal from the satellite to reach Earth is [tex]0.1157\ \text{s}[/tex].
You want to build a bicycle ramp that is 10 ft long and makes a 30 degree angle with the ground. What would be the height of the ramp?
PLZ HELP ME
Answer:
5.8 feet
Step-by-step explanation:
this problem uses a 30-60-90° triangle
the ratio of sides in a 30-60-90° triangle, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2
let 'h' = height of ramp
we can use this proportion, then cross-multiply:
10/h = [tex]\sqrt{3}[/tex]/1
[tex]\sqrt{3}[/tex]h = 10
h = 10/[tex]\sqrt{3}[/tex]
after rationalizing the denominator we get:
(10[tex]\sqrt{3}[/tex] ) ÷ 3 which is approximately 5.8 feet
Using the trigonometric ratio, the height of the ramp is 5.77 feet.
Length of bicycle ramp = 10 feet
Angle with the ground = 30°
What is the sine of an angle?The tangent of an angle is the ratio of the opposite side to the adjacent of the triangle.
Suppose the height of the ramp is h.
So, [tex]tan30=\frac{h}{10}[/tex]
[tex]h=10tan30[/tex]
[tex]h=\frac{10}{\sqrt{3} }[/tex]
[tex]h=5.77[/tex] feet.
So, the height of the ramp is 5.77 feet.
Hence, using the trigonometric ratio, the height of the ramp is 5.77 feet.

Alejandro plans to begin filling his backyard pool with water at noon. Assume noon represents t = 0 for time t in minutes. The depth of water in the pool is the product of the rate at which the water flows into the pool and time. The total depth of the water when the pool is full is 120 centimeters.
a. Alejandro begins filling his pool 15 minutes later than planned. Write the function relating the time since noon to the rate r at which water flows into the pool. Graph the function.
b. Analyze the key features of the graph in the context of the situation.

What are the measures of the acute angles?
Answer:
36.87° and 53.13°
Step-by-step explanation:
the legs of the right triangle are 3 and 4 and the hypotenuse is 5
tan x = 3/4
x = arctan (3/4)
= 36.87° = measure on one acute angle
90 - 36.87 = 53.13° = measure of the other acute angle

After the community clean up, the ecology club collected all the empty drink containers. There were 40 more 5 cent deposit containers than 10 cent deposit containers. If the club received $24.80 from the recycling center, how many 5 cent deposit containers did they have?
The number of 5-cent deposit containers the ecology club collected is 192.
What are the linear equations that represent the question?a - b = 40 equation 1
0.05a + 0.1b = $24.80 equation 2
Where:
a = number of 5-cent deposit containers b = number of 10- cent deposit containers.How many 5-cent deposit containers were collected?
The first step is to multiply equation 1 by 0.1
0.1a - 0.1b = 4 equation 3
Add equation 3 and equation 1
$28.80 = 0.15a
a = $28.80 / 0.15
a = 192

(COULD SOMEONE PLEASEEEE HELP ME♥️)$1000 invested at the bank is increasing 5% each year.How much money will be in the account at the end of year 10?
Answer:
The money in the account would be about 1628.91 at the end of year 10.
Step-by-step explanation:
1000 + 5% = 1050 Year 1
1050 + 5% = 1102.50 Year 2
1102.50 + 5% = 1157.63 Year 3
1157.63 + 5% = 1215.51 Year 4
1215.51 + 5% = 1276.29 Year 5
1276.29 + 5% = 1340.10 Year 6
1340.10 + 5% = 1407.11 Year 7
1407.11 + 5% = 1477.47 Year 8
1477.47 + 5% = 1551.34 Year 9
1551.34 + 5% = 1628.91 Year 10
Keep in mind that all of the numbers at the end of each year (1050 at year 1, 1102.50 at year 2) were rounded to the nearest cent. So the approximate amount of money at the end of year 10 would be 1628.91 dollars.

Consider two lines. Line A is given by the function f(x) = 4x − 9, while Line B contains the points (0, 5) and (2, 12). Which statement is true?
Answer:
line A has a greater slope than line B
Step-by-step explanation:
Complete question;
Consider two lines. Line A is given by the function g(x) = 4x − 9, while Line B contains the points (0, 5) and (2, 12). Which statement is true? A) Line A and Line B have the same slope. B) Line A has a greater slope than Line B. C) Line B has a greater slope than Line A. D) Line A slope is less than the slope of Line B.
Given the function expressed by line A as g(x) = 4x - 9
Compare with general equation of a line g(x) = mx+b
mx = 4x
m = 4
Hence the slope of the line is 4
If Line B contains the points (0, 5) and (2, 12);
Slope = y2-y1/x2-x1
Slope of line B = 12-5/2-0
Slope of line B = 7/2 = 3.5
This shows that line A has a greater slope than line B
