89 (54x − 36) + 2 = −3/4 (−40 + 16x) + 90xsolve for x

1 answer:

4 0

Hey! Just in case you have to show your work.

89(54x-36)+2=-3/4(-40+16x)+90x

4806x-3204+2=-3/4×4(-10+4x)+90x

4806x-3202=30-12x+90x

4806x-78x=30+3202

4728x=3232

3232÷4728=

X=404/591

What is the quadratic in vertex form that has an a value of 8 and a vertex of (5, 6)?

faltersainse [42]

Answer:

y= 8(x-5)² + 6

Step-by-step explanation:

Parabolas have two equation forms, namely; the standard and vertex form.

In the vertex form, y = a(x - h)² + k, the variables h and k are the coordinates of the parabola's vertex.

In this case; a=8, h =5, and k=6

Therefore;

The vertex equation will be

y= 8(x-5)² + 6

How should the decimal point in 8.403 be moved to determine the product of 10,000 × 8.403?

Troyanec [42]

Answer:

84,030.00 (Move the decimal point 4 to the right)

Step-by-step explanation:

When multiplying, move the decimal to the right! When dividing, move the decimal to the right!

Since, 10,000 has 4 zeros, we will want to move the decimal point four places to the right!

Hope this helps! :)

Gnom [1K]

Answer:

at + vi = vf

Step-by-step explanation:

In order to solve for vf, we need to isolate said variable.

a = vf - vi/t (Given)

at = vf - vi (Multiply t on both sides)

at + vi = vf (Add vi on both sides)

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri

vlada-n [284]

Option B: 256 is the diameter of the bacteria after 8 hours.

Explanation:

From the given, it is obvious that the graph is an exponential function.

The general formula is given by,

$y=a(b)^x$

Where a is the initial population,

b is the growth rate and

x is the number of hours.

It is given that the diameter of the bacteria doubles every hour.

Then, we have,

$b=2$

Let us substitute the coordinate (0,1) and $b=2$ , we get,

$1=a(2)^0$

$1=a$

Thus, substituting $a=1$ and $b=2$ in the general formula $y=a(b)^x$ , we have,

$y=1(2)^x$

We need to determine the diameter of the bacteria after 8 hours.

Let us substitute x = 8 in the equation $y=1(2)^x$ , we get,

$y=1(2)^8$

$y=1(256)$

$y=256$

Thus, the diameter of the bacteria after 8 hours is 256

Hence, Option B is the correct answer.
