Answer:
The expression is; x^2 – 4c + 4
Step-by-step explanation:
For the expression to be a perfect square, let us say the constant term should be assigned as ⇒ c;
This creates of following expression;
x^2 - 4x + c
In order to be a perfect square, the discriminant needs to be zero ;
( - 4 )^2 - 4 * ( 1 )c = 0 ,
16 – 4c = 0 ,
4c = 16 ,
c = 4 ,
Solution; The expression is, therefore; x^2 – 4c + 4

Help ASAP!!What is the volume of our planet if we assume that it is a sphere with the radius 3, 950miles? Round your answer to the nearest integer, use 3.14 for you calculations.
Answer: 258023743333miles³
Step-by-step explanation:
Volume of a sphere = 4/3πr³.
where,
π = 3.14
r = radius = 3950
Volume of a sphere = 4/3πr³.
= 4/3 × 3.14 × 3950³
= 4/3 × 3.14 × 61629875000
= 258023743333miles³
The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³

Step-by-step explanation:
Artur, Olga i Wiktor uczestniczyli w wyścigu. Wystartowali z tego samego miejsca, w tym samym momencie i biegną ze stałymi prędkościami. Gdy Artur ukończył bieg, Olga miała 15 m do mety,
a Wiktor miał 35 m. Gdy Olga ukończyła bieg, Wiktorowi pozostały 22 m do mety. Na jakim dystansie został rozegrany wyścig?
Answer:
165m
Question:
Artur, Olga and Wiktor participated in the race. They started from the same place at the same time and run at constant speeds. When Artur finished the race, Olga was 15 m to the finish,
and Wiktor was 35 m. When Olga finished the race, Wiktor remained 22 m to the finish. At what distance was the race held?
Step-by-step explanation:
Let Artur distance covered be =>x
When Artur covered distance x:
Olga was 15m from x
Olga = x - 15
Wiktor was 35m from x
Wiktor = x - 35
When Olga covered distance x:
Wiktor was 22m from x
The ratio of Olga to Wiktor:
(x-15)/(x-35) = x/(x-22)
Cross multiply
(x-15)(x-22) = x(x-35)
x² - 15x - 22x + 330 = x² - 35x
x² -37x +330 - x² + 35x = 0
-2x = -330
x = (-330)/(-2)
x = 165m
The race held at 165m distance
What is the measure of angle DAE?
Answer:
DAE=134-89=45
Step-by-step explanation:
SINCE BAF and CAE are opposite angles they are equal so
BAF=CAD+DAE
134=89+DAE
DAE=134-89=45
The measure of angle DAE is 45 degrees.
What is vertically opposite angle?when two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles.
According to the given question
m∠BAF = 134 degrees
and, m∠CAD = 89 degrees
Since, ∠CAE and ∠BAF are vertically opposite angles.
Therefore, m∠CAE = m∠BAF = 134 degrees
Now,
m∠CAE = m∠CAD + m∠DAE
⇒ m∠BAF = 89 + m∠DAE
⇒ 134 = 89 + m∠DAE
⇒ m∠DAE = 134 - 89
⇒ m∠DAE = 45 degrees
Hence, the measure of angle DAE is 45 degrees.

Type the correct answer in each box. Use numerals instead of words. Consider this quadratic equation. x2 + 2x + 7 = 21 The number of positive solutions to this equation is _______ . The approximate value of the greatest solution to the equation, rounded to the nearest hundredth, is _______ .
Answer:
-1 ± 3i√6
Step-by-step explanation:
Please write this quadratic equation as follows: x^2 + 2x + 7 = 21. The " ^ " indicates exponentiation.
The coefficients of this quadratic are 1, 2, 7.
Thus, the "discriminant" b^2 - 4(a)(c) is (2)^2 - 4(1)(7), or 4 - 28, or -24.
Because the discriminant is negative, this quadratic has two different complex roots:
-b ± √[ discriminant ] -2 ± 2i√6

Which is the parametric form of the polar equation r=-4 theta?
A. x=-4 cos theta, y=-4 sin theta
B. x=-4 theta cos theta, y=-4 theta sin theta
C. x=-theta cos theta, y=-theta cos theta
Answer: Option B.
Step-by-step explanation:
we have that r = 4*θ
(you writted a negative equation, but we can never have a negative radius)
We also have that:
r = √(x^2 + y^2) = 4*θ
We can use the relationship cos(x)^2 + sin(x)^2 = 1
and write X = A*cos(θ) and Y = A*sin(θ)
and now we have:
r = √( (A*cos(θ))^2 + (A*sin(θ))^2) = √(A)^2 = 4*θ
So the correct option is:
x = 4*θ*cos(θ) or -4*θ*cos(θ)
y = 4*θ*sin(θ) or -4*θ*cos(θ)
(We can have the positive or negative options because we are squaring the term, so the sign does not matter)
The correct option then is B
Answer:
C) x = -4θcosθ and y = -4θsinθ

Answer:
The volume of the pyramid is 5 cubic inches.Step-by-step explanation:
Assuming that the triangle base dimensions are 1 inche and 5 inches, and the height of the pyramid is 6 inches, the volume would be
[tex]V=\frac{1}{3}Bh[/tex]
Where [tex]B[/tex] is the area of the base (triangle) and [tex]h[/tex] is the height.
[tex]B=\frac{1}{2}bh =\frac{1}{2}(1)(5)=2.5 \ in^{2}[/tex]

On the diagram i need to fond the following measures of angles. Please help quickly!
Answer:
62° and 54°
Step-by-step explanation:
The exterior angle of a triangle is equal to the 2 opposite interior angles.
116° is an exterior angle of the triangle, thus
2x + 4 + 3x - 13 = 116, that is
5x - 9 = 116 ( add 9 to both sides )
5x = 125 ( divide both sides by 5 )
x = 25
Thus
∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°
∠ B = 2x + 4 = 2(25) + 4 = 50 + 4 = 54°
Rewrite the function by completing the square r^2+18x+80=0
Answer:
x = -10, -8
Step-by-step explanation:
x^2+18x+80=0
Subtract 80 from each side
x^2+18x=-80
Take the coefficient of x
18
Divide by 2
18/2 = 9
Square it
9^2 =81
Add 81 to each side
x^2+18x +81=-80+81
(x+ 9) ^2 = 1
Take the square root of each side
sqrt((x+ 9) ^2 )=±sqrt( 1)
x+9 = ±1
Subtract 9 from each side
x+9-9= -9 ±1
x = -9+1 x = -9-1
x = -8 x = -10
Answer:
x+9^2=1

plz solve -8 ( x - 3 ) - 4x = 48
Answer:
x = -2
Step-by-step explanation:
-8 ( x - 3 ) - 4x = 48
Distribute
-8x +24 -4x = 48
Combine like terms
-12x +24 = 48
Subtract 24 from each side
-12x+24-24 = 48-24
-12x = 24
Divide each side by -12
-12x/-12 = 24/-12
x = -2
Answer:
X= -2
Step-by-step explanation:
First, you need to distribute -8 into (x-3) ---> -8(x-3)-4x=48
-8x + 24 -4x= 48
Get numbers with variables on its own side--> -24 -24
-8x - 4x = 24
Combine -8x and -4x -----> -8x-4x = -12x -12x = 24
Divide ----------------------------------> -12 -12
24÷ -12 = -2

Answer:
Think of even square roots close to 27: the closest is 25 which has a square root of 5. Now think of the number with an even square root after 25: 36 which has a square root of 6. Since 27 is between 25 and 36, the square root of 27 would be between 5 and 6.

1/5 of a large peach pie. What fraction of the whole pie does each friend get? Let represent the fraction of the whole pie each friend gets.
Enter an equation as a multiplication equation.
The equation is n =.
Each friend gets off a whole pie.
Answer:
1/10
Step-by-step explanation:
1/5÷2/1=?
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
1/5×1/2=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×1 /5×2=1/10
This fraction cannot be reduced.
Therefore:
1/5×1/2=1/10
3) The sum of two numbers is 20. Their
difference is -2. What are the two numbers?
Answer: 9, 11 (or for the picture 48 and 52)
Step-by-step explanation:
The sum of two numbers (x, y) is 20;
x+y=20
One is 2 greater than than the other;
y=x+2
Now, we can put that in for y;
x+(x+2)=20
And solve;
2x+2=20
2x=18
x=9
Now, substitute in the value of x into the second equation;
y=9+2
And we get our answer.
y=11
