What’s a equivalent ratio

Ratios that are equivalent to each other are considered equivalent ratios. For example, 2:6 is equal to 6:18

Think of equivalent ratios as equivalent fractions, or fractions that are equal to each other.

An example of an equivalent ratio would be
1:2(or 1/2) = 2:4(or 2/4).

These two ratios are exactly the same, though they may not look anywhere near the same.

One way we could determine if two ratios are equivalent or similar, is by dividing the bigger side by the smaller side ( in our example, that would be 2/1 = 2), then divide the other side of the ratio by the same side ( 4/2 = 2 )

Since they are both equal to 2, we can say that they are the same, or equivalent.

I know this is a lot of information, but I hope this helped!

Factor the quadratic expression in the equation y=2x^2+28x+96 and use the factors to find the zeros of the equation. Then, use t
gavmur [86]

Answer:

x=-7

Step-by-step explanation:

We have been given an equation y=2x^2+28x+96. We are asked to find the zeros of equation by factoring and then find the line of symmetry of the parabola.

Let us factor our given equation as:

2x^2+28x+96=0

Dividing both sides by 2:

x^2+14x+48=0

Splitting the middle term:

x^2+6x+8x+48=0

(x^2+6x)+(8x+48)=0

x(x+6)+8(x+6)=0

(x+8)(x+6)=0

Using zero product property:

(x+8)=0\text{ (or) }(x+6)=0

x+8=0\text{ (or) }x+6=0

x=-8\text{ (or) }x=-6

Therefore, the zeros of the given equation are x=-8\text{ (or) }x=-6.

We know that the line of symmetry of a parabola is equal to the x-coordinate of vertex of parabola.

We also know that x-coordinate of vertex of parabola is equal to the average of zeros. So x-coordinate of vertex of parabola would be:

\frac{-8+(-6)}{2}=\frac{-14}{2}=-7

Therefore, the equation x=-7 represents the line of symmetry of the given parabola.

1. What is the volume, in cubic centimeters, of the sphere shown below? Use 3.14<br> for Pi
prohojiy [21]

Answer:

113.04 cm³

Step-by-step explanation:

diameter = 6cm

so radius = 3cm

Volume of sphere = \frac{4}3}\pi r^3

= 4 * 3.14 * 3 * 3 *3 / 3

=  4 * 28.26

= 113.04 cm³

for f(x)=1/x-5 and g(x)=x^2+2 find the expression for g(x) and substitute the value of g(x) into the function in place of x to f
IRISSAK [1]

Answer:

f(x)  = (1/x) - 5

g(x) = x^2 + 2

=> f[g(x)] = [1/(x^2 +2)] - 5
