Answers
9514 1404 393
Answer:
A, B, D
Step-by-step explanation:
For appropriate values of 'a', the log function has the following characteristics:
A: f(1) = 0B: f(a) = 1D: f(1/a) = -1Any log function will tend toward negative infinity as x tends to zero (for |a|>1).

Answers
81+164=245
360-245= 115
Answer is :115
The size of angle x is 115.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
The whole complete angle is 360.
This means,
164 + 81 + x = 360
Solve for x.
164 + 81 + x = 360
245 + x = 360
x = 360 - 245
x = 115
Therefore,
The size of angle x is 115.

Find the volume of the triangular prism in the picture shown. Round your answer to the
nearest tenth. *
1: 167
2:77.3 yd
3: 77 yd²
Answers
Given:
A figure of a triangular prism.
Height of triangular base = [tex]9\dfrac{2}{3}[/tex] yd
Base of triangular base = 4 yd
Height of prism = 4 yd.
To find:
The volume of the triangular prism.
Solution:
Volume of a triangular prism is:
[tex]V=Bh[/tex] ...(i)
Where, B is the area of triangular base and h is the height of the prism.
Area of triangular base is:
[tex]B=\dfrac{1}{2}\times base\times height[/tex]
[tex]B=\dfrac{1}{2}\times 4\times 9\dfrac{2}{3}[/tex]
[tex]B=2\times \dfrac{29}{3}[/tex]
[tex]B=\dfrac{58}{3}[/tex]
Putting [tex]B=\dfrac{58}{3}[/tex] and h=4 in (i), we get
[tex]V=\dfrac{58}{3}\times 4[/tex]
[tex]V=\dfrac{232}{3}[/tex]
[tex]V=77.33...[/tex]
[tex]V\approx 77.3[/tex]
The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.

four times a number
a number divided by 14
Answers
Answer:
#1. Fourteen divided by a number.
#2. Four times a number.
#3. A number divided by 14.
#4. A number minus 14.
Step-by-step explanation:
I hope this helps., I just need more points. So sorry.
"the quotient" means to divide.
"the quotient of 14" means 14 is going to be divided by something. So we can write:
14
÷
The something it will be divided by is "the difference between a number and -7".
Lets call "a number"
n
.
"the difference" means we are going to subtract something from
n
and what we are going to subtract is a

n

(

Putting this together gives:

Step-by-step explanation:
1. Use the Pythagorean theorem ([tex]A^{2} +B^{2} = C^{2}[/tex])
[tex]18^{2} +24^{2} =C^{2} \\324 + 576 = C^{2} \\900 = C^{2} \\\sqrt{900} = \sqrt{C^{2} } \\30 = C\\[/tex]
Step-by-step explanation:
so in this case, you use the pythagoras theorem:
hypotenuse= opposite squared + adjacent squaredsince we don't have a hypotenuse, let's name is H
soo it will be
H= 18 squared + 24 squared
H = 324+ 576
H= 900
so you find the square root of 900 which is 30
so, therefore the answer is 30
