Find the square root of 1764 using prime factorization with explanation and solution.
Answer:
42
Step-by-step explanation:
The product of the prime factors of 1764 is
1764 = 2² × 3² × 7² , thus
[tex]\sqrt{1764}[/tex]
= [tex]\sqrt{2^{2}(3^{2} )(7^{2} ) }[/tex]
= [tex]\sqrt{2^{2} }[/tex] × [tex]\sqrt{3^{2} }[/tex] × [tex]\sqrt{7^{2} }[/tex]
= 2 × 3 × 7
= 42

What is f(-2) of the function given below? *
f(x) = 3x2 - 4x + 1
Answer:
f(-2) = 21
Step-by-step explanation:
Step 1: Define
f(x) = 3x² - 4x + 1
f(-2) is x = -2
Step 2: Substitute and Evaluate
f(-2) = 3(-2)² - 4(-2) + 1
f(-2) = 3(4) + 8 + 1
f(-2) = 12 + 9
f(-2) = 21
- Find the coordinates of A if B(0,5.5) is the midpoint of AC and C has coordinates
(-3,6).
Given:
Coordinates of point C are (-3,6).
Point B(0,5.5) is the midpoint of AC.
To find:
The coordinates of A.
Solution:
Let the coordinates of point A are (a,b).
Formula for midpoint:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
Using the above formula, the midpoint of A(a,b) and C(-3,6) is
[tex]B=\left(\dfrac{a+(-3)}{2},\dfrac{b+6}{2}\right)[/tex]
[tex](0,5.5)=\left(\dfrac{a-3}{2},\dfrac{b+6}{2}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{a-3}{2}=0[/tex]
[tex]a-3=0[/tex]
[tex]a=3[/tex]
and,
[tex]\dfrac{b+6}{2}=5.5[/tex]
[tex]b+6=11[/tex]
[tex]b=11-6[/tex]
[tex]b=5[/tex]
Therefore, the coordinates of point A are (3,5).

Is 39,052 divisible by 3?
Answer:
no as the answer would be a decimal
Step-by-step explanation:
an easier way to know is to add up all the digits
3 + 9+0 +5+2= 19 and if that number is a multiple of 3 then it will be divisible by 3
this works for any number that should be divided by 3
example
is 2345 divisible by 3
2+3+4+5 =14 so no it is not divisible by 3
example
is 12345 divisible by 3
1+2+3+4+5 =15 so yes it is divisible by 3
hope this helps

PLZ HELP im am stupid
Answer:
x = 17
Step-by-step explanation:
The two indicated angles are corresponding and congruent, thus
11x - 31 = 8x + 20 ( subtract 8x from both sides )
3x - 31 = 20 ( add 31 to both sides )
3x = 51 ( divide both sides by 3 )
x = 17

Beach Bicycles sells two-seater bicycles. Its markup rate is 68%. Which equation represents the new price for a bicycle, y, given an original price, x?
Answer:
y = 1.68x
Step-by-step explanation:
The markup rate of a product or service refers to how higher the selling price is than the total production cost. In this case, this company doesn't produce the bikes, instead it purchases them from a wholesaler, distributor or even the factory, and then resells them in order to make a profit.
E.g. Beach Bicycles purchases two-seater bikes at $200 each, and then it will resell them to their customers at 1.68 x $200 = $336. The total markup in this example is $136, which represents $136/$200 = 68% of the purchase price.

What is the sum of the terms of the series 4 + 7 + 10 + . . . + 22? 91 43 104
Answer:
91Step-by-step explanation:
This is an arithmetic sequence, in which a set number is added to the previous term to get the next term. The number added is figured out by subtracting the 1st term from the 2nd term and the 2nd term from the 3rd term.
Now that we know the number is 3, we can complete the sequence:
4, 7, 10, 13, 16, 19, 22
We will add all the terms up to get 91.
___________________________________________________I AM ALWAYS HAPPY TO HELP :)Sovle for x . 4(x-4)=36
Answer:
below
Step-by-step explanation:
[tex]x.4 ( x-4) = 36 \\[/tex]
[tex]4x(x-4) = 36 \\[/tex]
[tex]4x^{2} - 16x = 36[/tex]
add -36 to both sides
[tex]4x^{2} - 16x - 36 = 36 -36 \\4x^{2} -16x - 36 = 0[/tex]
divide both sides by 2
[tex]\frac{4x^{2} - 16x - 36 }{4} = 0/4[/tex]
[tex]x^{2} -4x-9 = 0[/tex]

Step-by-step explanation:
Point B has 3 lines extending from it. One line extends to point A, another to C, and another to D. Angle A B D is a right angle. Which information do you know is true from the diagram? Check all that apply. ∠ABD is a right angle. Ray B C bisects angle ∠ABD. m∠ABC = 45° m∠CBD = 45° m∠ABD = 90°
Answer:
A) ∠ABD is a right angle.
E) m∠ABD = 90°
Step-by-step explanation:
just took the test
∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Given that,
Angle A B D is a right angle.
The right angle is a 90-degree angle.
So,
m∠ABD = 90°
Hence "∠ABD is a right angle and ∠ABD = 90° will be correct for the given angles".

PLEASE HELP ME IM BEGGING YOU
Answer:
A: 2x-1
Step-by-step explanation:
Graph it. if you plug in the x and y of (1,1)
1= 2(1)-1
1=2-1
correct
Answer: A
Step-by-step explanation:
Since we are given the slope, all we have to do is use the given point to find the y-intercept.
y=2x+b [plug in (1,1)]
1=2(1)+b [multiply]
1=2+b [subtract both sides by 2]
b=-1
Now, we know the equation is y=2x-1.
