Solve the equation using the method of completing the square.
2x^2 + 163 - 8 = 0
Answer:
D
Step-by-step explanation:
[tex]2x^2+16x-8=0[/tex]
Simplify:
[tex]x^2+8x=4[/tex]
Rewrite in the form [tex](x+a)^2=b[/tex]:
[tex]x^2+8x=4[/tex]
Add [tex]4^2[/tex] to both sides:
[tex]x^2+8x+4^2=4+4^2[/tex]
[tex]x^2+8x+4^2=20[/tex]
[tex]\left(x+4\right)^2=20[/tex]
[tex]x+4=\sqrt{20}[/tex] or [tex]x+4=-\sqrt{20}[/tex]
x = -4±[tex]\sqrt{20}[/tex]
x= -4±[tex]2\sqrt{5}[/tex]
someone help me with this I would really appreciate it !
Answer:
V = 126 [tex]mi^{3}[/tex]
Step-by-step explanation:
Volume of a pyramid is V = [tex]\frac{lwh}{3}[/tex]
l = length
w = width
h = height
width is 6 mi
length is 7 mi
height is 9 mi
V = [tex]\frac{6*7*9}{3}[/tex]
V = 126 [tex]mi^{3}[/tex]
Write an expression that represents the volume of a cube with side length 2x^3. (For any cube with side length s, v = s^3 = s.s.s^.)

Write the equation for the larger circle shown in the figure.
Write the equation for the smaller circle shown in the figure.
Answer:
See below for answers
Step-by-step explanation:
Given equation of the horizontal ellipse: [tex]\frac{x^{2}}{64}+\frac{y^{2}}{16}=1[/tex]
Standard form: [tex]\frac{x^{2}}{a^{2} }+\frac{y^{2}}{b^{2} }=1[/tex]
Values of a and b: [tex]\frac{x^{2}}{8^{2} }+\frac{y^{2}}{4^{2} }=1[/tex]
Therefore, the radius of the bigger circle is a=r=8 (half the length of the major axis) and the radius of the smaller circle is b=r=4 (half the length of the minor axis).
Given the equation for a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex], then:
The equation for the larger circle is [tex]x^{2} +y^{2} =8^{2}[/tex]
The equation for the smaller circle is [tex]x^{2} +y^{2} =4^{2}[/tex]

What is the gradient of the graph shown?
Give your answer in its simplest form.
Answer:
use desmos graphing calculator to help you find the answers
Step-by-step explanation:
x axis=(2,0)
y axis=(0,-4)
y intercept=-4
slope=3/2
PLEASE HELP FOR #2abc!!
Answer:
a) 2
b) 1
c) y =mx+b
Step-by-step explanation:
Slope = rise/run = Δy/Δx = 2/1 =2 [Δ means difference between 2 values]
To find slope we need to find by how many difference do the x and y increases or decreases. Here y increases by 2 and x increases by 1.
The constant just another way of asking y-intercept.
The slope-intercept form y=mx+b. [m=slope, b= y-intercept]
We will choose point (1,3) to input into the equation. You can use any point it would give the same answer.
3 = 2×1 +b
3 = 2 +b
b = 3-2
b = 1

A piece of fabric is for 1/6 yards long if 2 1/4 yards are cut off The Yards remain I'll see you
Answer:
2 1/12 yds remain
Step-by-step explanation:
1. You first change the denominators, so then the fractions will be alike. 2 1/4-1/6
2. Find the LCD or Least Common Denominator. 12 can go into and it is alike, so 2 3/12-2/12
3. Now we can find the answer!
So the answer is 2 1/12

find the value of x then find the angle measures of the polygon 65, x, (x-5)
Answer:
x = 60
Step-by-step explanation:
Assuming that there are no secret angles unmentioned, the figure in question is a triangle, as it has 3 angles. With this knowledge, we also know that a triangle contains 180°. So, we can do the following to solve for x.
65 + x + (x - 5) = 180
2x + 60 = 180
2x = 120
x = 60

In which number does the digit 2 have a value that is ten times as great as the value of the digit 2 in the number 135,284?
PLEASE HELP!
Answer:First and foremost, we should note that the value of the digit 2 in the number 135,284 is (200). Therefore, the value that is ten times as great as the value of the digit 2 in the number 135,284 would be:
= 10 × 200
= 2000
Therefore, the 2 must be in the thousands place. This can be seen in numbers such as:
172748.

Answer: A- 12.5 million
Step-by-step explanation: all you have to do is 125% of 10 million and you get 12.5 million.
Answer:
40 million
Step-by-step explanation:
125% of x
125/100 * x = 1.25x
x+ 10 = 1.25x
(subtract x from both sides)
10 = 1.25x - x
10 = 0.25x
(divide both sides by 0.25)
10/0.25 = x
x= 40

A line segment AB is increased along its length by 25% by producing it to C on the side of B . If A and B have the coordinates ( 1 , 2 ) and ( 5 , 6 ) respectively then find the coordinates of C.
Ans : ( 6 , 7 )
*Please show your workings*
Answer:
C = (6, 7)Step-by-step explanation:
Coordinates of point B in terms of A and C:
x = x₁ + (x₂ - x₁)*a/(a + b)y = y₁ + (y₂ - y₁)*a/(a + b)B(x, y) = (5, 6), A(x₁, y₁) = (1, 2), C(x₂, y₂) = ?Find the coordinates:
5 = 1 + (x₂ - 1)*4/5 ⇒ 4 = 4/5*(x₂ - 1) ⇒ x₂ - 1 = 5 ⇒ x₂ = 66 = 2 + (y₂ - 2)*4/5 ⇒ 4 = 4/5(y₂ - 2) ⇒ y₂ - 2 = 5 ⇒ y₂ = 7C = (6, 7)Todd can run 1/2 a mile in 1/12 of an hour. what is todd’s rate in miles per hour?
Answer:
Step-by-step explanation:
(1/2 mile)/(1/12 hour) = 12/2 = 1 mph
How long it takes someone to walk a trail depends on the length of the trail, which you did not provide. The formula is distance = rate*time, so time = distance/rate. You know the rate = 1 mph
