The vertex of the quadratic function y = x² + 10x + 24 is located at point B. (-5, -1). This is found by using the formula -b/2a for the x-coordinate and substituting the x coordinate into the function for the y-coordinate.
Explanation:The vertex of a quadratic function (a function in the form of y=ax²+bx+c) is the point that represents the minimum or maximum of the function graph. In this case, we are looking to find the vertex of the function y = x² + 10x + 24. The formula to find the x-coordinate of the vertex of a quadratic function is -b/2a. In this function, a = 1 and b = 10, giving us -10/(2*1) = -5 for the x-coordinate of vertex. We then substitute -5 into the function for x to determine the y-coordinate, resulting in y = (-5)² + 10*-5 + 24 = -1. Therefore, the vertex of the function is (-5,-1). So, the correct choice is B. (-5, -1).

in the rational expression below?
9x+45
x2 +9x+20
O A. x+4
O B. 9
0.0
D. X +5
Please help I’m stressed and I wanna cry MATH IS ANOTHER LANGUAGE TO ME
Answer: X+5
Step-by-step explanation:
When you take out the 9 it should be 9(x+5) and when you take out the 9x on the bottom it gives you (x+5)+20 therefore x+5 is your GCF.
I hope this helps :)
The greatest common factor (GCF) of the numerator 9x+45 and the denominator x^2 +9x+20 of the provided rational expression is x+5.
Explanation:The greatest common factor (GCF) is found by factoring both the numerator and the denominator and then identifying the largest factor that appears in both. For the provided rational expression 9x+45 over x2 +9x+20, let's factor both parts:
Numerator: 9x+45 can be factored out as 9(x+5).Denominator: x2 +9x+20 can be factored into (x+4)(x+5).Comparing both factored forms, we can see that x+5 appears in both the numerator and the denominator, and it is the largest factor common to both. Therefore, the GCF of the numerator and the denominator is x+5.

When solving for x, the sine of 44º is used. What other angle and trigonometric function could be used to solve for x? a. tan 46º c. tan 44º b. cos 46º d. cos 44º
Answer:
cos46°
Step-by-step explanation:
Using the co function identity
sin x° = cos(90 - x)°, hence
sin44° = cos(90 - 44)° = cos46°
Answer: The correct option is (b) cos 46°.
Step-by-step explanation: Given that when solving for x, the sine of 44º is used.
We are to select the other angle and trigonometric function that could be used to solve for x.
We know that,
the sine of any acute angle is equal to the cosine of its complement.
That is,
if y denotes the measure of any acute angle, then we have
[tex]\sin y=\cos(90^\circ-y).[/tex]
Therefore, if y = 44°, then we get
[tex]\sin 44^\circ=\cos(90^\circ-44^\circ)=\cos 46^\circ.[/tex]
Thus, the other angle and the trigonometric function that could be used to solve for x is cos 46°.

If the ratio of the areas of two similar polygons is 25:49, what is the ratio of the corresponding side length
Answer:
5:7
Step-by-step explanation:
Ratio of the areas of similar shapes is equal to the square of the scale:
A₂ / A₁ = r²
Ratio of the side lengths of similar shapes is equal to the scale:
s₂ / s₁ = r
Therefore:
A₂ / A₁ = (s₂ / s₁)²
25/49 = (s₂ / s₁)²
s₂ / s₁ = 5/7
The ratio of the side lengths is 5:7.
Answer:
5 : 7
Step-by-step explanation:
Given 2 similar figures then
ratio of sides = a : b
ratio of areas = a² : b²
Here the ratio of areas = 25 : 49, hence
ratio of sides = [tex]\sqrt{25}[/tex] : [tex]\sqrt{49}[/tex] = 5 : 7

Which of the following constants can be added to x^2 - 3x to form a perfect square trinomial?
A. 1 1/2
B. 2 1/4
C. 4 1/2
Answer:
B.2 1/41
Step-by-step explanation:
In a perfect square trinomial of the form ax+bx+c where a, b and c are constants, the value of (b/2)²=ac
In the provided equation the value of a=1, b=-3 c=?
Therefore, (-3/2)²=c since a-the coefficient of x²=1 and 1×c=c
c=2.25= 2 1/4
Thus the trinomial x² - 3x + 2 1/4 is a perfect square.

The product of a fraction and the sum of 5 1/3 and 6 1/3 is 3. What is the fraction?
Answer:
The fraction = 9/35
To find the fraction, calculate the sum of 5 1/3 and 6 1/3, which is 35/3, then divide the final product, 3, by this sum. The fraction that when multiplied by the sum equals 3 is 9/35.
The question asks us to find the fraction when the product of the fraction and the sum of 5 1/3 and 6 1/3 is 3.
First, let's calculate the sum of 5 1/3 and 6 1/3:
5 1/3 can be written as (5*3 + 1)/3 = 16/3.
6 1/3 can be written as (6*3 + 1)/3 = 19/3.
Adding these fractions, we get (16/3) + (19/3) = (35/3).
So, we have the equation:
Fraction imes (35/3) = 3
To find the unknown fraction, we divide both sides by 35/3:
Fraction = 3 / (35/3) = 3 imes (3/35) = 9/35
Therefore, the fraction we are looking for is 9/35.

To find slope you have to find the change in y over the change is x. 1--4=5 and 5-0=5. 5/5 is 1 so the slope, or m, is 1. x stays the same since it's the variable. it'll become y=1x-4 and since you don't have to place a coordinate of one in front of a variable, you can just write it as y=x-4

to create an all purpose cleaning product, 1.5 ounces of cleaner must be added to one gallon of water. How many ounces of cleaner will be added to 8.5 gallons of water?
Answer:
12.75 oz
Step-by-step explanation:
1 gallon is equivalent to 64 oz.
Writing and solving an equation of ratios, we get:
1.5 oz 1 gal
----------- = ------------
x 8.5 gal
Here we must cross-multiply to solve for x.
x(1 gal) = (1.5 oz)(8.5 gal) = 12.75 oz
Thus, x = 12.75 oz of cleaning product must be added to 8.5 gal of water to create the desired solution.
To make an all-purpose cleaner, you need 12.75 ounces of cleaner for 8.5 gallons of water.
This is determined by multiplying the ratio of 1.5 ounces per gallon by 8.5 gallons.
follow these steps:
First, determine the ratio of cleaner to water. The ratio is 1.5 ounces of cleaner per gallon of water.Next, multiply this ratio by the number of gallons to find the total amount of cleaner needed for 8.5 gallons of water.Calculate: 1.5 ounces/gallon * 8.5 gallons = 12.75 ounces.Therefore, 12.75 ounces of cleaner will be added to 8.5 gallons of water.
What is the frequency of the function f(x)?
f (x) = 3 cos (TX) – 2
Express the answer in fraction form.
Answer:
Frequency = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
We are given the following function and we are to find its frequency:
[tex]f (x) = 3 cos (\pi x) -2[/tex]
We know that the standard form of cosine function is [tex]y=Acos (Bx)+c[/tex]
where [tex]A[/tex] is the amplitude, [tex]B=\frac{2\pi}{\text{Period}}[/tex] while [tex]c[/tex] is the mid line.
Frequency is given by:
[tex]F=\frac{1}{P}[/tex] where [tex]F[/tex] is frequency and [tex]P[/tex] is the period.
Finding period by comparing the given function:
[tex]y=3cos(\pi x)-2[/tex]
[tex]Period - B = \pi[/tex]
Substituting B to get:
[tex]\pi =\frac{2\pi}{\text{Period}}[/tex]
[tex]\text{Period}=\frac{2\pi}{\pi}=2[/tex]
So, Period = 2.
Since frequency is [tex]\frac{1}{P}[/tex], therefore
Frequency = [tex]\frac{1}{2}[/tex]
The frequency is T / (2π).
To find the frequency of the function f(x) = 3 cos(T x) – 2, start by recognizing the standard form of a cosine function, which is f(x) = A cos(Bx + C) + D. Here, A, B, C, and D are constants with specific roles.
The frequency is found using the parameter B in the form Bx. The angular frequency B is equal to T in our function. Frequency (f) is related to angular frequency (ω) by the formula:f = ω / (2π)
Since ω = T:f = T / (2π)
Therefore, the frequency of the function f(x) = 3 cos(Tx) – 2 is T / (2π).
The sum of the page numbers on the facing pages of a book is 73. What are the page numbers?
Answer:
The page numbers are 36 and 37.
Step-by-step explanation:
n + (n + 1) = 73
2n + 1 = 73
n = (73 - 1)/2
= 72/2 = 36
Follow below steps:
The sum of the page numbers on the facing pages of a book is 73. To solve this, we need to establish that facing pages in a book are always one number apart. If we call one page number x, then the other page number is x+1 because page numbers are consecutive.
Now, we can create the equation x + (x+1) = 73 to find the value of x. Solving this equation, we get:
2x + 1 = 73
2x = 73 - 1
2x = 72
x = 72 / 2
x = 36
Since x is the lower of the two page numbers, then the pages are 36 and 37.
