Step-by-step explanation:
Just use the Pythagorean theorem.
[tex]\boxed{a^2+b^2=c^2}[/tex]
[tex]33^2 + 56^2 = c^2\\1089 + 3136 = c^2\\4225 = c^2\\c = \sqrt{4225} \\c= 65[/tex]
Answer:
Third side is 65
Step-by-step explanation:
FORMULA
a^2 + b^2 = c^2
PLUG IT IN
33^2 + 56^2 = c^2
33 and 56 are the legs of the triangle so they go into the A and B variable.
The legs make up the right angle.
C is the hypotenuse, and here it is the diagonal line in that image.
FIND THE NUMBERS SQUARED
1089 + 3136 = c^2
ADD THEM TOGETHER
4225 = c^2
SQUARE ROOT BOTH SIDES
[tex]\sqrt{4225}[/tex] = ([tex]\sqrt{C}[/tex])^2
65 = c
CHECK
33^2 + 56^2=65^2
1089 + 3136 = 4225
4225 = 4225

Elle placed a bucket under a leaky roof. The bucket was 310 full after 25 of an hour. How much water is leaking per hour?
Answer:
3/4 bucket
Step-by-step explanation:
Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour
Water leaking : time taken
Let x = amount of water leaking per hour
3/10 : 2/5 = x : 1
3/10 ÷ 2/5 = x / 1
3/10 × 5/2 = x / 1
15 / 20 = x / 1
Cross product
15 * 1 = 20 * x
15 = 20x
x = 15/20
= 3/4
3/4 bucket of water is leaking per hour
Which table shows a proportional relationship between x and y?

y 6 8 10 12
x 3 9 10 15
y 1 3 4 5
Can someone help i suck at math
Answer:
Table 3
Step-by-step explanation:
In a proportional relationship there must be a constant rate of change.
The first table:
6-5 / 9-7 = 1/2
5-3 / 7-4 = 2/3
These are not equal so it is not proportional.
The second table:
10-8 / 150-120 =2/30
8-5 / 120-75 = 3/45
These are not equal so it is not proportional
The third table:
10-8 / 12-10 =2/2 = 1
8-6 / 10-8 =2/2 = 1
These are equal so this table is proportional.

Let x and y be functions of time t such that the sum of x and twice y is constant. Which of the following equations describes the relationship between the rate of change of x with respect to time and the rate of change of y with respect to time?
9514 1404 393
Answer:
b) dx/dt = -2dy/dt
Step-by-step explanation:
We are given that ...
x(t) +2y(t) = k
for some functions x(t) and y(t) and some constant k.
Differentiating with respect to time gives ...
x'(t) +2y'(t) = 0
x'(t) = -2y'(t) . . . . . subtract the y term
In the form used in the answer choices:
dx/dt = -2dy/dt . . . . . matches choice B
Chose all possible zeros of the polynomial of h(x)=5x3 - 5x - 10x.
Answer:
The possible zeros/roots of the polynomial are
[tex]x = 0\\x=-\sqrt{3} \\ x=\sqrt{3}[/tex]
Step-by-step explanation:
[tex]h(x)=5x^3 - 5x - 10x[/tex]
[tex]h(x)=5x^3 -15x[/tex]
[tex]h(x)=5x(x^2 -3)[/tex]
When [tex]y= 0[/tex]
[tex]0=5x(x^2 -3)[/tex]
[tex]5x = 0 \implies x = 0[/tex]
[tex]x^2 - 3 = 0 \implies x=\pm\sqrt{3}[/tex]

(-4,9),(6,4) in point slope form
Answer: [tex]y-4=-\frac{1}{2} (x-6)[/tex]
Step-by-step explanation:
The point-slope form is y-y₁=m(x-x₁). y₁ and x₁ are from a point, and m is slope.
To find slope, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{4-9}{6-(-4)}=\frac{-5}{10}=-\frac{1}{2}[/tex]
Now that we have the slope, we can fill in our point-slope form equation.
[tex]y-4=-\frac{1}{2} (x-6)[/tex]
What is the slope of this line
Answer:
the slope is 1.
Step-by-step explanation: This answer is correct, because the rise over run was 2/2 which equals 1.
