Select the correct answer. The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number? A. The equation that represents this situation is 10 − x = -18. The second number is 28. B. The equation that represents this situation is 10 + x = -18. The second number is -28. C. The equation that represents this situation is x − 10 = -18. The second number is -8. D. The equation that represents this situation is -10 + x = -18. The second number is -8.
Answer:-28
Step-by-step explanation:
Let A is the second number
the first number is 10.
The total is -18
=> 10 + A =-18 <=> A=-18-10=-28

URGENT PLEASE HELP: x = -pi/2 is an asymptote in the graph of y = tanx.
True or False
Answer:
Step-by-step explanation:
tan is the same thing as sin/cos. therefore,
[tex]tan(-\frac{\pi}{2})=\frac{sin(-\frac{\pi}{2}) }{cos(-\frac{\pi}{2}) }[/tex]
[tex]sin(-\frac{\pi}{2})=-1[/tex] and [tex]cos(-\frac{\pi}{2})=0[/tex] so
[tex]tan(-\frac{\pi}{2})=-\frac{1}{0}[/tex] which is undefined. On the graph, this is represented by an asymptote. So your answer is true.
Answer:
Step-by-step explanation:
The answer is true!
Evaluate the function
f(x)=−4x^2+6x−4
Find f(5)
Hey there!
1. How to find f(5)?
To find f(5) - simply substitute x = 5 in the function. f(5) means the value of f(x) at x = 5.2. Substitution and Evaluate
[tex] \large{f(5) = - 4( {5})^{2} + 6(5) - 4}[/tex]
Remember to follow the PEMDAS/BODMAS rules! Exponent comes before multiplication.
[tex] \large{f(5) = - 4(25) + 30 - 4} \\ \large{f(5) = - 100 + 30 - 4} \\ \large{f(5) = - 74}[/tex]
3. Final Answer
f(5) = -74If you have any questions regarding the question or my answer, feel free to ask!

A mattress store in Stafford purchased a mattress at a cost of $255 and marked it up 100%. Later on, Cassie bought the mattress. If the sales tax in Stafford is 11%, how much did she pay in all?
Answer: 278.18
sorry if it's wrong
Step-by-step explanation: if you divide 255 by 11 you get 23.18181818181
so if you simplify you get 23.18 so that is the tax plus the original payment which is 278.18

2.50 - 0.75 = 1.75
If line segment PB = 12 cm, the area of sector ACB = ? cm2 (rounded

1\tfrac{2}{5} \div \frac{8}{9}
1 5/2 ÷ 9/8
Answer:
Step-by-step explanation:
What you wrote below the top line and the bottom line are not the same thing.
I think you really want the second line, but one can't be sure.
(1*2 + 5)/2 div (9/8)
7/2 // 9/8
7/2 * 8*9
7*8/18 = 56/18 = 28/9
If you really do want the top line (the latex) it is different.
1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.
(1*5 + 2)5 // (8/9)
7/5 // 8/9 Invert the bottom fraction and multiply
7/5 * 9 / 8
63 / 40
1 23/40

What is the length of PQ⎯⎯⎯⎯⎯?
Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth.
UPDATE- IT'S 5.2
Answer: ≈ 5.2
Step-by-step explanation:
You're gonna want to use the Law of Cosines to solve:
c² = a² + b² -2abcos(R)
c² = 6² + 9² - 2(6)(9)cos(34°)
c² = 36 + 81 - 108cos(34°)
c² = 117 - 108(.82904)
c² = 27.46368
√c² = √27.46368 => 5.2405 = 5.2
Question 3 math help please show work
Answer:
Use the referent of an adult stride (about 1 yard) to measure the dimensions of the area that will be covered by sod. Use the dimensions to calculate the area in square yards.
Step-by-step explanation:
This seems to be a relatively vague question, but it was requested so I'll try my best.
There's practically no way to accurately measure the area to be covered by sod without using a reference. I couldn't help but notice the list of references above the question, and I presume they are correlated. Since the length of an adult stride is 1 yard, you can use an adult stride as a reference to relatively accurately measure the dimensions of the area that needs to be covered. The method to find the area varies with the shape of the area, but assuming you can accurately find the area, this is a plausible way to estimate the area needed to be covered by sod. As an alternative, since the question stipulates sod can only be purchased in square yards or square meters, you can use a doorway (about 2 meters) in the list of references above the question to also measure the dimensions of the area. This is less practical because an adult stride is more mobile than a door.

Answer:
2 – will3 – will4 – will notStep-by-step explanation:
Whether the offered numbers will satisfy the inequality is more easily seen by solving it for x.
6 + 3x ≤ 15
3x ≤ 9 . . . . . . . . . subtract 6 from both sides
x ≤ 3 . . . . . . . . . . divide by 3
This is "x is less than or equal to three."

Given that f(x) = 4x + 5 and g(x) = x2 - 2x - 2, find (f + g)(x).
A) (f + g)(x) = x2 + 2x+3
B) (f + g)(x) = x2 + 6x+ 3
C) (f + g)(x) = -x2 + 6x + 7
D) (f + g)(x) = – x2 + 2x - 7
Answer:
A
Step-by-step explanation:
We are given the two functions:
[tex]f(x)=4x+5\text{ and } g(x)=x^2-2x-2[/tex]
And we want to find:
[tex](f+g)(x)[/tex]
This is equivalent to:
[tex]=f(x)+g(x)[/tex]
Substitute:
[tex]=(4x+5)+(x^2-2x-2)[/tex]
Rearrange:
[tex]=(x^2)+(4x-2x)+(5-2)[/tex]
Combine like terms. Hence:
[tex](f+g)(x)=x^2+2x+3[/tex]
