Calculate cos0 to two decimal places.
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
A cylinder has a base diameter of 10centimeters and a height of 7 centimeters. What is its volume in cubic centimeters, to nearest tenths place
Answer:
549.85cm^3
Step-by-step explanation:
Given data
Diameter=10cm
radius= 5cm
Height= 7cm
The expression for the volume of cylinder is given as
Volume= πr^2h
Substitute
Volume= 3.142*5^2*7
Volume= 3.142*25*7
Volume= 549.85cm^3
Hence the volume of the cylinder is 549.85cm^3

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

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]
Our answer is A.

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

-20=-8(a+4)-5(1-5a)
What is a
Answer:
a=1
Step-by-step explanation:
-20=-8(a+4)-5(1-5a)
Distribute
-20 = -8a -32 -5 +25a
Combine like terms
-20 =17a -37
Add 37 to each side
-20+37 = 17a-37+37
17 = 17a
Divide by 17
17/17 = 17a/17
1= a

A 2-column table with 6 rows. The first column is labeled x with entries negative 4, negative 3, negative 2, negative 1, 0, 1. The second column is labeled f of x with entries negative 10, 0, 0, negative 4, negative 6, 0.
Which is a y-intercept of the continuous function in the table?
(0, –6)
(–2, 0)
(–6, 0)
(0, –2)
Answer:
(0, –6)
Step-by-step explanation:
Given
[tex]x \to f(x)[/tex]
[tex]-4 \to -10[/tex]
[tex]-3 \to 0[/tex]
[tex]-2 \to 0[/tex]
[tex]-1 \to -4[/tex]
[tex]0 \to -6[/tex]
[tex]1 \to 0[/tex]
Required
The y intercept
This is the point where x =0
From the table, we have:
[tex]x \to f(x)[/tex]
[tex]0 \to -6[/tex]
Hence, the y intercept is: (0, –6)
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

What is the solution of -17 = -2y + 13 – 8y?
Answer:
3
Step-by-step explanation:
-17 = -2y + 13 - 8y
-17 = -10y + 13
-30 = -10y
3 = y
y = 3
Answer:
y = 3
Step-by-step explanation:
- 17 = - 2y + 13 - 8y
- 10y + 13 = - 17
- 10y + 13 - 13 = - 17 - 13
- 10y = - 30
- 10y ÷ - 10 = - 30 ÷ - 10
y = 3
Consider the equation below
-2(bx -5 ) =16
Answer:
bx = - 3
Step-by-step explanation:
- 2(bx - 5) = 16
- 2bx + 10 = 16
- 2bx + 10 - 10 = 16 - 10
- 2bx = 6
- 2bx ÷ - 2 = 6 ÷ - 2
bx = - 3
