Answer:

40 exhibits dose the aquarium have.

Second model represent the problem.

Step-by-step explanation:

let number of exhibits dose the aquarium have = x

According to given condition;

90% of x = 36

(90/100) x = 36

x = (36×100)/90

x = 40

40 exhibits dose the aquarium have.

Second model represent the problem.

Y = x^2 + 6 doesn’t not belong in the group.

When graphing an x squared it will appear as an parabola (an U shaped graph).

As you can see the rest of the linear equation uses y=mx + b, except for the 3rd one.

Factor completely 3x^2+2x-1

Morgarella [4.7K]

Answer:

(3x - 1)(x + 1)

Step-by-step explanation:

3x^2 factors into 3x and x.

-1 factors into -1 and 1.

Now we try different positions of 3x, x, -1, and 1 until we find the correct factorization.

Try: (3x - 1)(x + 1)

When you multiply the two factors together, the middle term will be 3x - x = 2x

Since 2x is the original middle term, this is the correct factorization.

Answer: (3x - 1)(x + 1)

Answer:

c = 5

Step-by-step explanation:

The graph of

f(x) = 3x² -5x -7

is shifted 2 units to the right by the transformation ...

g(x) = f(x -2)

g(x) = 3(x -2)² -5(x -2) -7

g(x) = 3(x² -4x +4) -5x +10 -7

g(x) = 3x² -17x +15

When this is written as a monic polynomial, it is

g(x) = x² -17/3x +5

The value of 'c' is 5.

Noa was walking in the forest and measured the circumference of two trees that he found. The first tree measured 37 5/8 inches a

rodikova [14]

Answer:

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>

Step-by-step explanation:

1. Let's review carefully all the steps taken by Noa to calculate the difference of the circumferences of the two trees.

Circumference Tree 1 = 37 5/8 inches around

Circumference Tree 2 = 45 1/3 inches around

Step 1: 45 1/3- 37 5/8

The measures are correct, no issues copying them.

Step 2: 45 8/24 - 37 15/24

Noa looked for common denominators

1/3 * 8/8 = 8 /24 is correct; 5/8 * 3/3 = 15/24 is also correct.

Step 3: 44 32/24 - 37 15/24

Noa looked for making the fraction part higher on the left side:

45 8/24 = 44 32/24 is correct because 24/24 = 1

Step 4: 44 32/24 - 37 15/24= 8 17/24

<u>Here we can finally find out the mistake done by Noa. The result is 7 17/24 and not 8 17/24.</u>
