A 10 -foot ladder is leaning against a building. The base of the ladder is 3 feet from the side of the building. How high does the ladder reach along the side of the building? Answer exactly or round to 2 decimal places.
Answers
Answer:
The ladder is 5.20 feet tall on the side of the building
Step-by-step explanation:
Here, we simply want to calculate the height the ladder is from the base of the building
To get this, we need a pictorial representation of what we have here.
From what we have here, we have a right-angled triangle with a hypotenuse of 10 foot and a base of 3 feet
We apply Pythagoras’ theorem to get how far is the tip of the ladder from the base of building
Pythagoras’ stated that the square of the hypotenuse equals the sum of the squares of the two other sides
In this case, let the height be x
So;
x^2 + 3^2 = 6^2
x^2 = 6^2 - 3^2
x^2 = 36 - 9
x^2 = 27
x = √27
x = 5.196 feet
which to two decimal places is 5.20 feet

Chris labels every lattice point in the coordinate plane with the square of the distance from the point to the origin (a lattice point is a point such that both of its coordinates are integers). How many times does he label a point with the number $25$?
Answers
Answer:
4 times
Step-by-step explanation:
A lattice point may be defined as the point of intersection of two grid lines or more than two grid lines that is placed in a regularly spaced points arrays. This is called a lattice point.
In the context, Chris tries to label every lattice point in a coordinate plane with its square of distance from the point to its origin. The lattice points means that the numbers are both the integers. So for number 25, Chris has to label 4 times

line.
Answers
Answ
Step-by-step explanation:
Two point slope =-(-6+6)/(6-2) =0
Equation is y+6 = 0(x-2)
y+6=0
y=-6
The point is -6 at y axis which is a horizontal line.
Write an equation in point-slope form of the line that passes through the point (2,1) and has a slope of 2
Answers
Answer:
y-1=2(x-2)
Step-by-step explanation:
Since the slope is 2, that number is multiplied by x. Then the y subtracts the x value point and the x subtracts the y.
An equation in point-slope form of the line that passes through the point (2,1) and has a slope of 2 is y=2x-3.
Given that, the coordinate point is (2, 1) and slope m = 2.
What is an equation in point-slope form?The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The standard form of the slope intercept form is y=mx+b.
Put (x, y) = (2, 1) and m = 2 in y=mx+b and solve for b.
That is, 1=2(2)+b
⇒ b = -3
Now, substitute m = 2 and b = - 3.
So, y=2x-3
Therefore, an equation in point-slope form of the line that passes through the point (2,1) and has a slope of 2 is y=2x-3.

squares q,r,t form a right triangle with dimensions as shown in the diagram. what is the area of square Q
Answers
Answer:
The area of square Q is 441 m² ⇒ C
Step-by-step explanation:
Let us use the right triangle to find the side of square Q
∵ The length of the side of square T = 29 m
∴ The length of the hypotenuse of the right triangle = 29 m
∵ The length of the side of square R = 20 m
∴ The length of leg1 of the right triangle = 20 m
∵ (leg1)² + (leg2)² = (hypotenuse)² ⇒ Pyathagoras Theorm
∴ (20)² + (leg2)² = (29)²
∴ 400 + (leg2)² = 841
→ Subtract 400 from both sides
∴ (leg2)² = 441
→ Take √ for both sides
∴ leg2 = 21
∵ Leg2 is the side of the square Q
∴ The length of the side of square Q = 21 m
∵ Area of the square = side × side
∴ Area of square Q = 21 × 21
∴ Area of square Q = 441 m²
∴ The area of square Q is 441 m²

The gallons of way used to take a shower varies directly with the number of minutes in the shower .If a 6 minute shower uses 36 gallons of water, find the constant of variation
Answers
Answer:
constant of variation (k) = 6
Step-by-step explanation:
Let us first represent the sentence in direct variation expression:
"the gallons of water used to take a shower varies directly with the number of minutes in the shower"
Let the gallons of water used = g
Let the number of minutes spent in the shower = m
g ∝ m
where: ∝ = sign of proportionality
This means that as g increases, m increases also, and the same holds for decrease too.
g ∝ m
g = km
where k = constant of variation ( or proportionality constant)
Next, If a 6-minute shower uses 36 gallons of water, find the constant of variation
g = 36 gallons
m = 6 minutes
∴ g = km
= 36 = k × 6
k = 36 ÷ 6 = 6
k = 6
