Answer:
x = {-9/4, 15/4}
Step-by-step explanation:
To use the square root property to solve the quadratic, you need to get it to a form where the square root function can be usefully applied. That will mean having a square of a binomial on one side of the equal sign, and a constant on the other side of the equal sign.
We can get that from the given equation by adding 5 to both sides.
(x -3/4)^2 -5 = 4 . . . . . . given
(x -3/4)^2 = 9 . . . . . . . add 5 to get the square by itself
x -3/4 = ±3 . . . . . . . . . take the square root
x = ±3 +3/4 = {-9/4, 15/4} . . . . add 3/4 and expand the result

A dilation produces a smaller figure. Which is a possible scale factor? –2 One-third 1 4
Answer:
1/3 (one-third)
Step-by-step explanation:
A scale factor that produces an image smaller than the original figure is less than 1. A scale factor that produces an image bigger than the original figure is more than 1.
Thus, the only option that's less than 1 is one-third.

Answer:
option c
Step-by-step explanation:
Quadratic function in vertex form:
y = a(x - h)² + k
Where (h, k) is the vertex
vertex(5 , 12)
y = a(x - 5)² + 12
This passes through (8, 9)
9 = a(8 - 5)² + 12
9 = a(3)² + 12
9 = 9a + 12
9 - 12 = 9a
9a = -3
a = -3/9
a = -1/2
[tex]Answer:\ y = \dfrac{-1}{3}(x - 5)^{2}+12[/tex]

Find volume of sphere:

[tex]\rightarrow 9[/tex]
Therefore proved 9 such spheres can be made using the metal cone.
We know that volume of cone is [tex]12\pi a^3[/tex]
[tex]\sf \rightarrow 12\pi a^3 = 12936[/tex]
[tex]\sf \rightarrow a^3 = \dfrac{12936}{12\pi}[/tex]
[tex]\sf \rightarrow a = \sqrt[3]{\dfrac{12936}{12\pi}}[/tex]
[tex]\sf \rightarrow a =7[/tex]
Therefore the radius of sphere is 7 cm
An ostrich is
running at a speed
of 43 miles per
hour
Is it proportional or non proportional
The relationship iof the ostrich running at 43 miles per hour is proportional.
Speed of the ostrichSince speed = distance per unit time
The speed of the ostrich is 43 miles per hour. This means that the ostrich covers a distance of 43 miles every hour.
Since the ostrich always covers a distance of 43 miles every hour, we see that distance is proportional to time.
So, the relationship iof the ostrich running at 43 miles per hour is proportional.

A line passes through the point (-10,-7) and has a slope of
2 Write an equation in slope-intercept form for this line.
Answer: Below
Step-by-step explanation:
so using slope intercept form, we know that y = mx + b. We plug in our values. Since -10 is the x value and -7 is the y value, and 2 is the slope:
-7 = 2(-10) + b
Simplify.
-7 = -20 + b
13 = b
We plug b into the slope intercept form, this time without an x or y value to make it apply to all points on the line.
y = 2x + 13
That's our answer.

The angles shown below are supplementary:
10x
70°
What is the value of x?
O 100
O 110
O 20°
021
Answer:
x=11
Step-by-step explanation:
supplementary angles add up to 180 degrees
10x + 70 =180
10x = 110
x=11
11x10 = 110
110+70 = 180
f(x) = 6x + 4. Find the inverse of f(x).
A. f^-1(x) = 6x - 4
B. f^-1(x) = x-6/4
C. f^-1(x) = 4 - 6x
D. f^-1(x) = x-4/6
D. f-1(x) = x-4/6
Step-by-step explanation:
y = 6x + 4
-4
y-4 = 6x
÷6
y-4/6 = x
(Swap y and x around to find the inverse)
Inverse will be:
x - 4/6 = y
So, f-1(x) = x-4/6

1. Assume that segments that appear to be tangent are tangent.
Find ML to the nearest tenth.
2. Assume that segments that appear to be tangent are tangent.
Find WY.
1. Applying the pythagroean theorem, ML = 6.4.
2. Applying the two tangents theorem, WY = 37.
What is the Two Tangents Theorem?The two tangents theorem states that two tangents drawn from a circle to meet at a point outside the circle are congruent.
Thus:
1. ΔJKL is a right triangle, find JL using the Pythagorean theorem:
JL = √(16² - 9.6²)
JL = 12.8
Therefore:
ML = 1/2(JL)
ML = 1/2(12.8) (radius of circle)
ML = 6.4.
2. Based on the two tangents theorem, we have:
43 - 2x = 12x + 1
-2x - 12x = -43 + 1
-14x = -42
x = 3
WY = 43 - 2x
Plug in the value of x
WY = 43 - 2(3)
WY = 37

If 60% of a number is 90, what is the number
Answer:
60% in a fraction is: 60/100
60/100 of a variable, x, is equal to 90.
So we format it this way and solve for x;
60/100 * x = 90
60/100x = 90
0.6x = 90
/0.6 /0.6
x = 150, is the number.
