Answer: pink one

Step-by-step explanation:

The convert form of vertex equation y = -3(x+5)² - 4 in standard equation is y = -3x² - 30x - 79.

The standard form of the equation is ax²+bx+c=y and the vertex form of the equation is y= a(x-h)²+k,

Where k is a constant.

The given equation is,

y = -3(x+5)² - 4

To convert this vertex form of equation is standard form,

Simplify,

y = -3(x²+ 25 + 10x) - 4

y = -3x² -75 - 30x - 4

y = -3x² - 30x - 79

The required standard form of equation is y = -3x² - 30x - 79.

Answer:

Explanation:

1.) Rewrite √24 = [tex]\sqrt{4*6} = 2\sqrt{6}[/tex]   Rewrite √54 =[tex]\sqrt{9*6}= 3\sqrt{6}[/tex]

Divide both terms by the denominator; √6 cancels. 2-3 = -1

2.) Rewrite as [tex]\frac{3}{2\sqrt{5}}[/tex] ×[tex]\frac{10\sqrt{2}}{3\sqrt{5}}[/tex]  The 3's cancel.  10/2 = 5√2 in the numerator.

√5 × √5 = 5 in the denominator.  The 5's cancel.

That leaves √2 ≈1.4142

3.) Divide the terms in the numerator by the term in the denominator.

√2's cancel.  10π/2 = 5π   8π/2 = 4π  

Subtract and we are left with π = 3.14159

4.) [tex]\pi\sqrt{\frac{5}{3}}\cdot\pi\sqrt{\frac{3}{5}}[/tex]  The square roots are reciprocals. They multiply to 1

We are left with π × π = π² ≈  9.8696

Answer:

Step-by-step explanation:

There are zeros at x=-1 and x=4, so numerator factors of (x +1) and (x -4).

There are vertical asymptotes at x=1 and x = -2, so denominator factors of (x-1) and (x+2).

There is a hole at x=-3, so another numerator factor of (x+3) to cancel the one in the denominator.

Comparing the above to the given expression for f(x) we see that ...

Step-by-step explanation:

Solve for x when √(x ² - 4) = 1 :

√(x ² - 4) = 1

x ² - 4 = 1

x ² = 5

x = ±√5

We're looking at x ≤ 0, so we take the negative square root, x = -√5.

This means f (-√5) = 1, or in terms of the inverse of f, we have f ⁻¹(1) = -√5.

Now apply the inverse function theorem:

If f(a) = b, then  (f ⁻¹)'(b) = 1 / f '(a).

We have

f(x) = √(x ² - 4)   →   f '(x) = x / √(x ² - 4)

So if a = -√5 and b = 1, we get

(f ⁻¹)'(1) = 1 / f ' (-√5)

(f ⁻¹)'(1) = √((-√5)² - 4) / (-√5) = -1/√5

The sign must be negative; see the attached plot, and take note of the negatively-sloped tangent line to the inverse of f at x = 1.

90.9091 yeah I'm pretty sure

The number 20 is 22% of 90.91.

Percentage is a way of expressing a portion or fraction of a whole as a proportion of 100. It is denoted by the symbol "%". Percentages are commonly used to compare relative values, express ratios, or represent portions of a whole.

To estimate the number that 20 is approximately 22% of, we can set up the equation:

0.22 x = 20

Here, x represents the unknown number we are trying to estimate.

To estimate x, we can divide 20 by 0.22:

x ≈ 20 / 0.22

x ≈ 90.91

Therefore, 20 is 22% of 90.91.

Answer:

p + 30 = 20

Step-by-step explanation:

we can add 30 to both sides to make this an addition equation:

p - 20 = -30 (now add 30 to both sides)

p - 20 + 30 = 0 (then, add 20 to both sides)

p + 30 = 20 (this would be the addition equation)
