The equation of function g(x) = 2(x -7)² - 1, and the values of h and k are 7 and -1, respectively.

A quadratic equation is the second-order degree algebraic expression in a variable.

The standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

The function is given as:

f(x) = 2x² - 1

When the function is translated with 7 units left, the transformation rule is:

(x,y) -> (x + 7, y)

So,

g(x) = 2(x -7)² - 1

A quadratic function is expressed as:

g(x) = a(x -h)² + k

By comparison, the values of h and k are 7 and -1, respectively.

Step-by-step explanation:

24.

AC = 12 = cos(angle) × AB = cos(angle) × 13

imagine a circle with center in A and radius 13.

that is why we can say AC = cos(angle) × radius, and BC = sin(angle) × radius.

cos(angle) = 12/13 = 0.923076923...

angle = 22.61986495...°

so, B is the right answer.

25.

we have a right-angled triangle.

from the point in the ground, where the ladder starts, to the point on the wall, where the ladder ends, and the point on the ground right under the wall point.

at this ground point there is the right angle.

at the ladder ground point we have 70°.

so, the angle at ladder/wall point is

180 - 90 - 70 = 20°.

remember, the sum of all angles in a triangle is always 180°.

the ladder itself (20 ft) is the Hypotenuse (the baseline opposite of the 90° angle).

the height of the ladder/wall point is one leg (and what we need to calculate), and the ground distance from the ladder/ground point to the point right under the ladder/wall point is the second leg.

we can use the law of sine :

a/sin(A) = b/sin(B) = c/sin(C)

with the sides being always opposite of the associated angles.

so, we have

20/sin(90) = 20/1 = 20 = height/sin(70)

height = 20×sin(70) = 18.79385242... ft

so, D is the right answer.

=> x + 5 = 37 /3

=> (x+5) 3 = 37

When we add two negative numbers, the result will be negative.

When we add a negative and a positive number, the result can be positive, negative, or equal to zero.

When we add two positive numbers, the result will be positive.

These are both negative numbers. We know this because they are both to the left of 0. When we add two negative numbers, we will get a result that is less than 0.

k is a negative number while n is a positive number.

Notice that on the number line, k and n appear to be at a equal distance away from 0. This means that if we were to take their absolute values, they would be equal.

This means that adding k and n would result in an answer of 0.

m is a negative number while n is a positive number.

Notice that on the number line, n appears to be further away from 0 than m is. m is very close to 0.

This means that the absolute value of n would be greater than that of m. The result would therefore be positive

Both these numbers are negative. Adding them would produce a negative result.

The only value of the angles that could not be the value of the θ is determined as 240⁰.

If sinθ is given as [tex]\frac{\sqrt{3} }{2}[/tex], then the value of θ is determined as follows;

sinθ = √3/2

sinθ = 0.866

θ = sin⁻¹(0.866)

θ = 60⁰

When the angle is translated in radians, θ  = π/3 = 180/3 = 60⁰

thus, θ  = π/3

2(π/3) = 2(60) = 120⁰

using the following formula, we can obtain the rest;

θ = π/3 + 2πk

when k = 1;

θ = π/3 + 2π(1)

θ = 60 + 2(180)

θ = 420⁰

Thus, the only value of the angles that could not be the value of the θ is determined as 240⁰.

Sort the digits out from greatest to least, and form a number.

The number 92,581 is represented in standard form as the sum of its place values: 90,000 + 2,000 + 500 + 80 + 1.

Standard form is a way to represent numbers using digits.

In standard form, each digit's value is determined by its position in the number.

Given 9 ten thousands + 2 thousands + 5 hundreds + 8 tens + 1 one.

9 ten thousands means we have 9 sets of ten thousands, which is 9 × 10,000 = 90,000.

2 thousands means we have 2 sets of thousands, which is 2 × 1,000 = 2,000.

5 hundreds means we have 5 sets of hundreds, which is 5 × 100 = 500.

8 tens means we have 8 sets of tens, which is 8 × 10 = 80.

1 one is the value 1.

Now, let's add up all these values:

90,000 + 2,000 + 500 + 80 + 1

= 92,581.

So, the number 92,581 is represented in standard form as the sum of its place values: 90,000 + 2,000 + 500 + 80 + 1.
