Answer:
y=24
Step-by-step explanation:
since the triangles are similar, their sides are all in proportion
meaning:
[tex] \frac{20}{15} = \frac{32}{y} [/tex]
simplify the fraction
[tex] \frac{4}{3} = \frac{32}{y} [/tex]
cross multiply once the fraction is simplified
[tex]96 = 4y[/tex]
y=24
Answer:
y = 24
Step-by-step explanation:
the first triangle 20 : x : 32
the 2nd triangle 15 : 21 : y
Solve the equation of two triangles by similarity
x = [tex]\frac{21 * 20}{15}[/tex] = 28
y = [tex]\frac{21 * 32}{28}[/tex] = 24

Answers
Answer:
-3; (8, -20)
Step-by-step explanation:
to find the rate of change we do (y2 - y1) / (x2 - x1)
basically we choose 2 points on y and subtract them while using the 2 points on x and subtracting them
after subtracting them we divide change of y by change of x
for this one i chose (3, -5) and (6, -14)
-14 - (-5) = -9
6 - 3 = 3
-9 / 3 = -3
the rate of change is three
to find the y intercept we can use this equation
y = -3x + b
and then plug in things
ill plug in the first set of coordinates
-5 = -3(3) + b
-5 = -9 + b
b = 4
so the y intercept is b
using this equation
y = -3x + 4
we can find out what value y is when the x value is 8
-3(8) + 4 = -20

Step-by-step explanation:
6. the formula for the area of a circle is πr², and you have that r, or the radius, is 7. then, you just plug that in, which would be π·7² = π·49 = 49π.
7. the formula for the area of a parallelogram is base times height, and you have base = 6 cm and height = 7 cm. this means the area is 6 · 7 = 42.
8. The formula for the area of a triangle is base times height divided by 2, and you have base = 5 and height = 7. this means the area is 5 · 7 ÷ 2 = 35÷2 = 17.5

Answer:
y = 18
Step-by-step explanation:
Direct variation means y will change by the same factor x does. When x changes by a factor of 15/10 = 1.5, the value of y will change by that same factor
x = 10, y = 12
x= 15, y = 1.5×12 = 18
The new value of y is y = 18.
_____
Written as a proportion, you have ...
y/15 = 12/10
y = 15×12/10 = 18
__
Written as a direct variation equation, you have ...
y = kx
12 = k·10 ⇒ k = 1.2
y = 1.2·15 = 18 . . . . for x=15

Convert:
a) 5810 to base 2
b) 101112 to base 10
Step by step would be awesome
Answers
I suppose you mean to convert 58₁₀ to base 2, and not 5810₁₀ to base 2.
Write 58 as the sum of the largest powers of 2 that you can:
58 = 32 + 26
58 = 32 + 16 + 10
58 = 32 + 16 + 8 + 2
58 = 2⁵ + 2⁴ + 2³ + 2¹
58 = 1×2⁵ + 1×2⁴ + 1×2³ + 0×2² + 1×2¹ + 0×2⁰
⇒ 58₁₀ = 111010₂
To convert from base 2 to base 10, write out and simplify the decimal expansion as in the last line of the previous example.
10111₂ = 1×2⁴ + 0×2³ + 1×2² + 1×2¹ + 1×2⁰
10111₂ = 16 + 0 + 4 + 2 + 1
⇒ 10111₂ = 23₁₀

x -Intercepts: (_,_) and (_,_) Type answers smallest to largest left to right.
Axis of Symmetry: x=
Vertex:

Range: y≥
Answers
Answer:
Below in bold.
Step-by-step explanation:
y=x^2−4x−12
Factored form: y = (x - 6)(x + 2)
x-intercepts: (-2, 0) and (6, 0).
Axis of symmetry is found by converting to vertex form:
y = x^2−4x−12
y = (x - 2)^2 - 4 - 12
y = (x - 2)^2 - 16.
So axis of symmetry is x = 2.
Vertex is at (2, -16)
Domain is all Real Numbers.
Range is y ≥ -16.
