Mathematics
1 answer:
Morgarella [4.7K]3 years ago
8 0

Answer:

d) x=25

Step-by-step explanation:

x-16=9

add 16 to both sides canceling out -16 and adding 9 and 16, making it positive 25

after moving 16 to the other side of the =, and adding it to 9 it should look like:

x=25

therefore making the answer x=25

To the nearest tenth, what is the area of a circle whose radius is 2.2 feet?
Alja [10]
Area = π r^2
π = 3.14
r = 2.2
Area = 3.14 * 2.2^2
Area = 3.14 * 4.84
Area = 15.1976 You should round this somewhere. Perhaps 15.2 is the better answer rounded.

What is the logarithmic function modeled by the following table? x f(x) 9 2 27 3 81 4
Aliun [14]

Answer:

The logarithmic function modeled by the given table:

f(x) = log₃x

Step-by-step explanation:

Given Table:

x     f(x)

9     2

27    3

81    4

We can see that x increases as powers of 3. And f(x) is the power.

We assume that f(x) = log₃x

Checking using the table:

for x = 9

f(x) = log₃9 = 2

for x = 27

f(x) = log₃27 = 3

for x = 81

f(x) = log₃81 = 4

Hence proved.

Please Help. It Is A Or B for answers!
Anna35 [415]

Answer:

Step-by-step explanation:

A: x = 12-4 = 8

B: x =  12/4 = 3

No wonder you asked for help. Some of the questions don't make sense!

x+3 = 9 ⇒ x=6, which doesn't match either A or B.

3·x = 9 ⇒ x=3, which matches B

9 = 3·x is the same as the previous equation, i.e., B.

3+x = 9, doesn't match either A or B.

x = 9-3, doesn't match either A or B

x = 9÷3 ⇒ x=3, which matches B

x+x+x = 9 ⇒ x=3, which matches B

I'm guessing that there is an error in tape A, and x should be 6, not 8.

HOW DO YOU FIND ANGLE 1
Minchanka [31]

Answer:

If we add up all the angles of any triangle, we should get 180 degrees. Therefore, Angle C = 90 (angle A) - 45 (angle B) = 45 degrees. Since there was a ray drawn from A through C the exterior angle of angle C is angle 1.

Step-by-step explanation:

a "one angle" A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees. ... Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.
