Answer:
X = 24
Step-by-step explanation:
Just apply H² = B² + P²
(26)² = (10)² + P²
676 = 100 = P²
676 - 100 = P²
P² = 576
P = √576
P = 24
P = X

What is the equation of the line that passes through the point (−1,−3) and has a slope of 3?
Answer:
y= 3x
Step-by-step explanation:
The slope is just read. It is 3. It is the value of m in the general equation.
y = mx + b
y = 3x + b
To find b, use (-1,-3)
x = -1
y = -3 Substitute into the general equation
-3 = 3(-1) + b Simplify the right side
-3 = -3 + b Subtract -3 from both sides
b = 0
Answer: y = 3x

Which mixture would taste different? Mixture 1: 1 cup water, 1.5 teaspoons drink mix Mixture 2: 2 cups water, 1/2 teaspoon drink mix Mixture 3: 1 cups water, 1/4 teaspoon drink mix Mixture 1 Mixture 2 Mixture 3
Answer:
Drink 1 will taste different.
Step-by-step explanation:
Given the mixtures:
Mixture 1: 1 cup water and 1.5 teaspoons drink mix
Mixture 2: 2 cups water and [tex]\frac{1}{2}[/tex] teaspoons drink mix
Mixture 3: 1 cup water and [tex]\frac{1}{4}[/tex] teaspoons drink mix
To find:
Which of the mixtures will taste different?
Solution:
To answer this, we need to find the ratio of all the mixtures.
First of all, Let us make ratio of water as 1 quantity.
Ratio of 1st mixture = 1 : [tex]\frac{3}{2}[/tex]
Ratio of Mixture 2 contains 2 cups of water.
Let us divide the ratio of mixture 2 with 2, we get:
[tex]\frac{2}{2}:\dfrac{\frac{1}{2}}{2}\\\Rightarrow 1:\dfrac{1}{4}[/tex]
Ratio of 3rd mixture = [tex]1:\frac{1}{4}[/tex]
Ratio of drink mix of 1st mixture with 1 cup water is different.
So, drink 1 will taste different.

Answer:
Question 9
(a) The distance, Jalaj walks in one day is 4.4 km
(b) The amount Jalaj raises after walking for 22 km at the end of the 5 days is $8
Question 10
(b) The difference between the largest and smallest areas is 2,400 m²
Step-by-step explanation:
Question 9
(a) The distance Jalaj walks in 5 days = 22 km
Whereby Jalaj walks equal distance every day, we have;
The distance, Jalaj walks in one day = 22 km/5 days = 4.4 km/day
The distance, Jalaj walks in one day = 4.4 km
(b) The amount he raises for every kilometer he walks = $1.60
The amount he raises after walking for 22 km at the end of the 5 days = 5 × $1.60 = $8
Question 10
(b) The given side length of the square = 120 meters to the nearest 10 meters
Therefore;
The maximum dimension for the side length of the square = 120 + 10/2 = 125
The largest possible area of the square, [tex]A_l[/tex] = 125 m × 125 m = 15,625 m²
The minimum dimension for the side length of the square = 120 m - 10 m/2 = 115 m
The smallest possible area of the square, [tex]A_s[/tex] = 115 m × 115 m = 13,225 m².
The difference between the largest and smallest areas, [tex]A_l[/tex] - [tex]A_s[/tex] = 15,625 - 13,225 = 2,400 m².

Solve the following equation, -2(x-2)=4 for x. Show your work please
Answer:
x = 0
Step-by-step explanation:
Divide by -2
-2(x - 2)/-2 = 4/-2
x - 2 = - 2
Add 2 to both sides
x - 2 + 2 = - 2 + 2
x = 0
Answer:
x = 0
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -2*(x-2)-(4)=0
This is how your equation should look like (0 - 2 • (x - 2)) - 4 = 0
Solve: -2x = 0
Multiply both sides of the equation by (-1) : 2x = 0
Divide both sides of the equation by 2: x = 0
Please mark as branliest.

A golfer hits a golf ball off a tee. A quadratic function models the height of the golf ball in the coordinate plane, with the origin representing the initial location of the golf ball. Which of the following features can be used to determine the height that the golf ball travels from its initial location to the point where the golf ball starts falling towards the ground? Select ALL that apply.
A
zeros
B
vertex
C
y-intercept
D
end behavior
Answer:
a zeros
Step-by-step explanation:
The height that the golf ball travels from its starting point to the point where it begins to fall toward the ground can be calculated using the zeros of the equations. Option A is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, a golfer hits a ball off a tee. The height of the golf ball in the coordinate plane is represented by a quadratic function, with the origin being the golf ball's initial position.
The equations give the relation of height, time, and velocity in terms of the quadratic equation is,
h = -t² + vt + s,
Since s is the height in feet and v is the initial velocity in feet/second, one may determine the ball's maximum height.
After solving the equation and finding the values of zeroes gives the maximum height.
Thus, the height that the golf ball travels from its starting point to the point where it begins to fall toward the ground can be calculated using the zeros of the equations. Option A is correct.

f(x) = x + 2
g(x) = 3x^2 - 5
Find (f•g)(x).
Step-by-step explanation:
(f o g)(x)
= f(3x² - 5)
= (3x² - 5) + 2
= 3x² - 3.
(f.g)(x) = 3x^2 - 3
f(x) = x + 2
g(x) = 3x^2 - 5
equation is the relationship between variable and represented as is example of polynomial equation.
f(x) = x + 2
g(x) = 3x^2 - 5
now putting the x = g(x)
in f(x) = x + 2
Thus,
f(g(x)) = 3x^2 - 5 + 2
f(g(x)) = 3x^2 - 3
Thus, (f.g)(x) = 3x^2 - 3
