1) A 30-ft. ladder leans against a wall so that the base of the ladder
is 10 ft. from the base of the wall. What angle does the ladder
make with the ground?
A) 70.5
B) 19.5
C) 18.4
D) 33.3
Answer:
A) 70.5
Step-by-step explanation:
cos x = adjacent side/ hypotenuse
cos x = 10/ 30
cos x = 0.3
cos 70 = 0.3420
cos 71 = 0.3256
x = 70.5

Answer:
-4.3s+0.6t-2.6
Step-by-step explanation:
Add like terms:
-3.5t+4.1t-4s-0.3s+4.5-7.1
= 0.6t-4.3s-2.6
= -4.3s+0.6t-2.6

Answer:
(-1, -2.5)
Step-by-step explanation:
The midpoint formula is just basicallyadding both of the x values and then dividing the sum of them by 2, after that you will be adding both y values and then dividing them by 2, then you will get the midpoint x and y coordinate values. You can look up midpoint formula on google to see how it's actually written. You have to make sure to add correctly when you are using the negative numbers, because they can actually turn the equations into subtraction. Keep in mind, it can beconfusing sometimes when you are working with positive and negative numbers together. So make sure to just double check your work and also to make sure you added correctly.

Use the ratio test to determine whether the series is convergent or divergent.2 +4/2^2 + 8/3^2 + 16/4^2 +
Answer:
The result is 2 > 1. Hence, the series diverges
Step-by-step explanation:
You have the following series:
[tex]2+\frac{4}{2^2}+\frac{8}{3^2}+\frac{16}{4^2}+...+\frac{2^n}{n^2}=\sum_{i=1}^{i=n}a_n[/tex] (1)
You use the ratio test to determine if the series is convergent or divergent. The ratios test is given by:
[tex]\lim_{n \to \infty} \frac{a_{n+1}}{a_n}[/tex] (2)
Then, you replace the series (1) in (2):
[tex]\lim_{n \to \infty} \frac{\frac{2^{n+1}}{(n+1)^2}}{\frac{2^n}{n^2}}= \lim_{n \to \infty} \frac{(2^n2)(n^2)}{2^n(n+1)^2}\\\\\lim_{n \to \infty} \frac{2n^2}{n^2+2n+1}= \lim_{n \to \infty} \frac{2n^2}{n^2[1+\frac{2}{n}+\frac{1}{n^2}]} \\\\\lim_{n \to \infty} \frac{2}{1+\frac{2}{n}+\frac{1}{n^2}}=\frac{2}{1+0+0}=2[/tex]
In the ratio test you have that if the limit is greater than 1, the series diverges.
The result is 2 > 1. Hence, the series diverges.
5(7 + 3x) - 12 how to simplify
To solve this we need to use this formula:
a(b+c)=ab+ac
5(7+3x)-12=35+15x-12=15x+23
Answer:
Step-by-step explanation:
Multiply the 5 to the 7 and 3x--> 35 + 15x -12. Then add 12 to the -12, making it 0 (inverse operations), and add 12 to the 35 making it 47 + 15x. :) Then you would simply divide the 15 by 15x (making the variable by itself). your answer for x should be 47/15. :> If I helped, please mark brainliest!!

Write the phrase as a unit rate.
$13.50 for 3.6 lb
Alb
Please help FAST
Answer:
$3.75/lb
Step-by-step explanation:
First, let's set up a proportion. The top number represents the cost, while the bottom number represents how many pounds. In order to get a unit rate, we need to figure out how much it costs for 1 pound.
[tex]\frac{13.5}{3.6} =\frac{x}{1}[/tex]
Now, cross multiply. To cross multiply, you would multiply 13.5 by 1 and 3.6 by x.
[tex]13.5 * 1 =13.5\\3.6*x=3.6x[/tex]
Set these two equal to each other.
[tex]13.5=3.6x[/tex]
Divide both sides by 3.6 to get x.
[tex]\frac{13.5}{3.6} =\frac{3.6x}{3.6}\\x=3.75[/tex]
For unit rates, you have to write your answer as per unit. To do that, put a slash next to your answer, and then your unit.
$3.75 / lb (unit)
Complete the equation of the line whose slope is -2 and y-intercept is (0,-8)
y=
Answer:
y = -2x - 8
Step-by-step explanation:
We want to find the slope-intercept form of this equation. Slope-intercept form is denoted by: y = mx + b, where m is the slope and b is the y-intercept.
We already know that the slope is -2, so that means m = -2.
We also know the y-intercept (or the point where the line crosses the y-axis) is (0, -8), which means b = -8.
Thus, our equation is: y = -2x - 8.

Answer:
3.5 putts
Step-by-step explanation:
Mean: 26 + 31 + 32 + 39 = 128/4 = 32
32 - 26 = 6
32 - 31 = 1
32 - 32 = 0
32 - 39 = 7
Mean Absolute Deviation (MAD): 6 + 1 + 0 + 7 = 14/4 = 3.5
