Find the value of $c$ that makes $x^2+20x+c$ a perfect square trinomial. $c=$ Write the expression as the square of a binomial. The expression is .
9514 1404 393
Answer:
c = 100(x +10)²Step-by-step explanation:
The square of a binomial is ...
(x +a)² = x² +2ax + a²
Comparing this to your expression, we have ...
2a = 20 . . . . x-coefficient
a² = c . . . . . . constant term
Then ...
a = 20/2 = 10
a² = 10² = 100 = c
The square is then ...
(x +10)²
Answer:
c = 100 makes this a perfect square trinomial
Step-by-step explanation:
[tex]x^2+20x+c\\x^2+20x+100\\=(x+10)^{2}[/tex]
2.3 × 2² ÷ 2- 8·9 help please
Answer:
67.4
Step-by-step explanation:
Please look at number 10. from the slope and write the equation for me
Answer:
y = 8x + 38
Step-by-step explanation:
To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)
y = mx + b
y = 8x + b
6 = 8(-4) + b
6 = -32 + b
+32 +32
38 = b
So using our slope and our intercept we have our slope intercept
y = mx + b
y = 8x + 38
Hope this helps :)
Answer:
y - y1 = m(x - x1)
y - 6 = 8(x - (-4))
y - 6 = 8(x + 4)
y - 6 = 8x + 32
y = 8x + 32 + 6
y = 8x + 38
Step-by-step explanation:
First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.
After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.
Then you add 6 to both sides of the equation to isolate the y.
The slope-intercept equation ends up looking like this: y = 8x + 38
Hope this helps :)
The speed of light is 3 x 10^8 meters/second. If the sun is 1.5 X 10^11 meters from earth, how many seconds does it take the sunlight to reach the Earth? (Time = Distance/Speed).
Answer:
Time = 500 seconds or 8.333 minutes
Step-by-step explanation:
Time = Distance/Speed
Speed of light = 3 x 10^8 meters/second
Distance=1.5 X 10^11 meters
Time = 1.5 X 10^11 meters/3 x 10^8 meters/second
We solve using the scientific notation. When 8 is taken to the top it is subtracted from 11 ( the base 10 is the same -- laws of exponents)
Dividing 1.5 by 3 gives 0.5 .
Time = 1.5 X 10^(11- 8) meters/3 meters/second
Time = 0.5 X 10^3 seconds
Time = 500 seconds
Dividng seconds with 60 will give minutes
Time= 500/60 = 8.333 minutes

a pool of linen container 100 meters. three butete brought 15.75 meters, 22.50 meters and 12.25 meters respectively. how many meters of line was left after the sale
49 m
Answer:
49.5 meters of linen were left after the sale.
Step-by-step explanation:
Given that there are 100 meters of linen
And 15.75, 22.50 and 12.25 meters are sold.
This means that the sold linen has to be added to find the total linen sold.
And then the quantity of sold linen will be subtracted from 100 to find the meters of linen left.
[tex]Total\ linen\ sold = 15.75+22.50+12.25 = 50.5\ meters[/tex]
Left linen will be:
[tex]=100-50.5 = 49.5[/tex]
Hence,
49.5 meters of linen were left after the sale.

find the length of a diagonal AB in the rectangular prism
Hi there!
[tex]\large\boxed{AB = 32.60 in}[/tex]
Find the length of AB by finding the length of its base:
We can use sine to solve for the length of the Hypotenuse of the triangle located in the base:
sin = O / H
sin 50° = 24 / H
h * sin 50° = 24 ----> h = 24 / (sin 50°)
h ≈ 31.33 in
Use the Pythagorean Theorem to solve for the length of the diagonal since we have solved for the base of the triangle:
c² = a² + b²
c² = 31.33² + 9²
c² = 1062.57
c ≈ 32.60 in
AB = 32.60 in
could anyone help with this, im terrible at geometry haha
Answer:
m<ACD = 90
m<CDB = 126
m<EDB = 54
m<CDE = 180
Step-by-step explanation:
Well you have the right girl! *In honors geometry you can trust me!
Ok first thing...We already know
B = 54
A = 90
D = 54 (It's the Alternate interior angle of B)
C = 90
m<ACD = 90 (C = 90)
m<CDB = 126 (D = 54 ------> 180-54= 126)
m<EDB = 54 (Alternate Interior angle of B)
m<CDE = 180 (It is a straight line)
Hope this helps ya!!

Suppose (ideally) a hammer claw moves a distance of 0.10 meters to remove a nail. If a resistance force of 1500 N is exerted by the claw, and you move the handle of the hammer 0.5 meters, what is the effort force?
Answer:
7500 N
Step-by-step explanation:
Given that,
A hammer claw moves a distance of 0.10 meters to remove a nail.
Resistance force, F = 1500 N
The person move the handle of the hammer 0.5 m
We need to find the effort force. Let it is F'. The mechanical advantage is given by :
[tex]m=\dfrac{effort}{resistance}=\dfrac{d_i}{d_o}[/tex]
Where [tex]d_i\ \text{and}\ d_o[/tex] are input and output distance respectively.
[tex]m=\dfrac{F'}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=0.2\\\\F=7500\ N[/tex]
So, the effort force is 7500 N.
What is the answer to this question.

6x + 3y = 54
How do i find the variable
Answer:
there are two variables x and y which variable do u need to find or do u need it in point slope form
Answer:
Simplifying
6x + 3y = 54
Solving
6x + 3y = 54
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
6x + 3y + -3y = 54 + -3y
Combine like terms: 3y + -3y = 0
6x + 0 = 54 + -3y
6x = 54 + -3y
Divide each side by '6'.
x = 9 + -0.5y
Simplifying
x = 9 + -0.5y

What’s the answer
Answer: Sure,
Step-by-step explanation:
The form ax^2 + bx + c = 0 is called standard form of a quadratic equation. Before solving a quadratic equation using the Quadratic Formula, it's vital that you be sure the equation is in this form. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions.
Answer: That is standard form.
