d. 515
b
Ο Ο Ο Ο
d
Answers
Answer:
The simplest radical form is [tex]9\sqrt{5}[/tex] ⇒ (c)
Step-by-step explanation:
To simplify any square root;
Factorize the number under the root using prime numbersTake out the root any number repeated twice as one numberExamples:
1. Simplify [tex]\sqrt{8}[/tex]
factorize 8 using prime numbers
8 = 2 × 2 × 2, then [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]
Take two of 2 out the root, then [tex]\sqrt{8}=2\sqrt{2}[/tex]
2. Simplify [tex]\sqrt{18}[/tex]
factorize 18 using prime numbers
18 = 2 × 3 × 3, then [tex]\sqrt{18}=\sqrt{(2)(3)(3)}[/tex]
Take the two 3 out the root, then [tex]\sqrt{18}=3\sqrt{2}[/tex]
Let us simplify [tex]3\sqrt{45}[/tex]
∵ 45 = 3 × 3 × 5
∴ [tex]3\sqrt{45}=3\sqrt{(3)(3)(5)}[/tex]
→ Take the two 3 out by one 3
∴ [tex]3\sqrt{45}=3(3)\sqrt{5}[/tex]
→ Multiply the numbers out the root
∴ [tex]3\sqrt{45}=9\sqrt{5}[/tex]
∴ The simplest radical form is [tex]9\sqrt{5}[/tex]

Find the x and y intercept of the following equation 4x-10y=20
Answers
For the given linear equation we have:
y-intercept: y = -2x-intercept: x = 5.How to find the intercepts for the linear equation?Here we have a linear equation:
4x -10y = 20
First, let's find the y-intercept, this is the point with x = 0, so evaluating in that we get:
4*0 - 10y = 20
-10y = 20
y = 20/-10
y = -2
The x-intercept is what we get by evaluating in y = 0.
4x - 10*0 = 20
x = 20/4
x = 5

Find f'(x) if f(x)=3x- 12
Answers
Answer:
4
Step-by-step explanation:
f(x) = 12 and f(x) = 3x
12/3 = 4 and the function for f(x) is 3(4)
The derivative of the function f(x) = 3x - 12 is 3.
What is a derivative ?Derivative of a function measures the rate of change of a function it can also be defined as the slope of the function.If given dy/dx it states the rate of change of y with respect to x.
According to the given question we have find the first derivative of the function f(x) = 3x - 12.
Given f(x) = 3x - 12
f'(x) = 1(3)x¹⁻¹ + 0 ( derivative of any constant is 0 )
f'(x) = 3x⁰.
f'(x) = 3.

Find the percent of change: original:80 new:64
Answers
80 − 64 = 16
Now we need this difference as a percentage:
16
64
×
100
=
25 %
Explanation:
We divide by 64 because we want to know how much the number has changed from its original value.
We multiply by 100 because 'per cent' means 'how many out of 100'.
Explanation:
The formula for calculating the percent change in a value between two points in time is:
p=N−O/ O⋅ 100
Where:
p is the percent change - what we are solving for in this problem.
N is the New Value - 80 in this problem.
O is the Old Value - 64 in this problem.
Substituting and solving for
p gives:
p = 80 − 64/ 64 ⋅ 100
p = 16 /64 ⋅100
p = 1600 / 64
p = 25
The percentage change between 64 and 80 is a 25% increase.
So it’s 2

perimeter is adding up all the outside line measures, so for the squares with only one side value, just multiply that by four
the other ones, for the measure given for one side, the opposite side is the same measure, so just add that up.

Answers
Answer:
a = 4, b = 6 and c = 5
Step-by-step explanation:
It is given that,
[tex]\dfrac{\dfrac{1}{4}}{\dfrac{5}{6}}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{1}{4}\times \dfrac{6}{5}=\dfrac{1}{a}\times \dfrac{b}{c}[/tex]
If we compare both sides of the equation we get,
a = 4, b = 6 and c = 5
Hence, these are the values of a,b and c.

A partir da pergunta, somos instruídos a fingir que o número total de bombons (chocolate) que ela fez = 24 bombons
Do total de chocolates que ele fez, 2/3 são de coco.
