What is the mean of Geometric 9 and 36?

Mathematics
1 answer:
Snowcat [4.5K]3 years ago
4 0

Answer:

Mean is 18

Step-by-step explanation:

We would set up the proportion as X/9=36/X so after we cross multiply we get x^2=324. Then we find the square root of both sides to simplify. ... And the square root of 324 is 18. So the final answer is x=18 or the geometric mean is 18

Colin received a bonus check for 2,500$. He is going to deposit the money into his bank account that receives 5.5% simple intere
alex41 [277]
This is the concept of financial mathematics, the simple interest rate is given by:
S.I.=(PRT)/100
where:
P=principle=$2500
R=rate=5.5%
T=time=1 year
Hence;
S.I.=(5.5*2500.1)/100
=$137.5
Thus the total amount he had after 1 year will be:
2500+137.5
=$2,637.5

Which function in vertex form is equivalent to f(x) = x^2 + 6x + 3?
OlgaM077 [116]
f(x)=x^2+6x+3

Complete the square:

x^2+6x+a^2\implies a=\dfrac{6x}{2x}=3\implies x^2+6x+3^3

And we have:

f(x)=x^2+6x+3\\\\f(x)=x^2+6x+3^2-3^2+3\\\\f(x)=(x+3)^2-9+3\\\\\boxed{f(x)=(x+3)^2-6}

Answer B.

What can be concluded about the line represented in the table? Check all that apply. x y –6 –7 2 –3 8 0 The slope is 2. The slop
Stels [109]
The first thing we must do for this case is to find the equation of the line.
 y-yo = m (x-xo)

 We have then:
 m = (y2 - y1) / (x2-x1)

m = (-3 - 0) / (2-8)

m = 1/2
 We choose an ordered pair:
 (xo, yo) = (8, 0)

 Substituting values:
 y-0 = (1/2) (x-8)

y = (1/2) x - 4
 
 From here we conclude:

 Intersection with y:
 
We evaluate x = 0 in the function:
 y = (1/2) (0) - 4

y = -4

 Slope of the line:
 m = 1/2


 Point (-2, -5):
 
We evaluate the value of x = -2 and the value of y = -5
 -5 = (1/2) (- 2) - 4

-5 = -1 - 4

-5 = - 5
 The equation is satisfied.

 Point (8, 0):
 
It is part of the table, therefore belongs to the line.

 Answer:
 
The slope is 1/2
 
The y-intercept is -4.
 
The points (-2, -5) and (8, 0) are also on the line.
