Answer:
C
Step-by-step explanation:
To evaluate f(3) substitute x = 3 into f(x), that is
f(3) = [tex]\frac{1}{6}[/tex] × 3 = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex] → C

find the area of a semi circle with radius 12cm give your answer in terms of pi
Answer:
72pi
Step-by-step explanation:
The formula for the area of a circle is pi*r^2
Since three radius is 12, then it’s pi*12^2
pi*12^2= 144 x pi but that’s the area of a whole circle so divide by 2 and you get:
72pi
Answer:
226.195 cm²
In terms of pi:
A = (π · 12²) ÷ 2
Step-by-step explanation:
A = πr²
A = π · 12²
A = π · 144
A = 452.39
452.39 ÷ 2
226.195

replace the # symbols in the row 1 function to match the graph below f(x)=(x+5)(x+#)(x-1)(x-#)
Answer:
3, 5
Step-by-step explanation:
Looking at the graph, the x-intercepts are -5, -3, 1 and 5.
Hence the graph equation is (x+5)(x+3)(x-1)(x-5)

Work out the size of angle ABD.
(4 marks)
please help asap ill give brainliest
Answer:
∠ ABD = 42°
Step-by-step explanation:
∠ ODC = 90° ( angle between tangent and radius )
∠ ADC = 90° - 48° = 42°
The angle between a tangent and a chord is equal to the angle in the alternate segment, that is
∠ ABD = ∠ ADC = 42°

Find the surface area of the figure below.
Round to the nearest tenth. Do not
use commas in your answer or units of
measures. Only use numbers and decimals.
Answer:
2167.7 sq yds
Step-by-step explanation:
SA(cone) = πr² + πrs ('s' = slant height)
= π(15)² + π(15)(31)
= 225π + 465π
= 690π
= 2167.7

40°
3
Answer:
D
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] ab sinC ( a, b are the sides and C the angle between them ) , then
A = [tex]\frac{1}{2}[/tex] × 5 × 3 × sin40° = 7.5 × sin40° ≈ 4.8 units² ( to nearest tenth )

29/6 + 31/6 = 60/6 = 10
Write the equation of the line in fully simplified slope-intercept form.
Answer:
[tex]y=-\frac{1}{4} x-6[/tex]
Step-by-step explanation:
The slope-intercept form is [tex]y=mx+c[/tex], where m is the slope of the line and c is where the line crosses the [tex]y[/tex]-axis.
To calculate [tex]m[/tex] we can use the formula [tex]m = \frac{dy}{dx}[/tex] where [tex]dy[/tex] is the difference in [tex]y[/tex] between two points and [tex]dx[/tex] is the difference between [tex]x[/tex].
Information we can get from the graph given: [tex]c=-6[/tex]. Since [tex]c[/tex] is the point at which the line crosses the [tex]y[/tex]-axis.
To find [tex]m[/tex] let's get two points from the graph.
Point 1: [tex](4,-7)[/tex]
Point 2: [tex](8,-8)[/tex]
Now use the equation [tex]m = \frac{dy}{dx}[/tex].
[tex]m = \frac{-7 - (-8)}{4-8} = -\frac{1}{4}[/tex].
Now we have [tex]m[/tex] and [tex]c[/tex], let's put them back into the general equation.
[tex]y=-\frac{1}{4} x-6[/tex]

Harper is getting a new rug in her bedroom. Her bedroom is in the shape of a rectangle with a length of 9 feet and a width of 14 feet. If the rug cost $1.75 per square foot, how much will it cost to purchase the rug?
Answer:
D) 220.50
Step-by-step explanation:
9x14 = (9x9)+(9x5) =126 126 x 1.75 (.75x126) + 126 = 220.50
AKA: 9x14 = 126 126 x 1.75 = 220.50

In a relaxed practice setting with no pressure, the average player should be able to make at least ten in a row. But free throws typically come in pressure situations, so managing the pressure is as important as practicing form.
seven hamburgers and four sodas cost $27.35. Four hamburgers and five sodas cost $18.75
I need to find the equation of each sentence.
WILL MARK BRAINLIEST (or however you spell it)
Answer:
equations:
7x + 4y = 27.35
4x + 5y = 18.75
Step-by-step explanation:
x = burgers
y = sodas
---------------------------------
7x + 4y = 27.35
4x + 5y = 18.75
If the angles 2xº and 4yº
are
complementary, find the value of x + 2y.
Answer:
Solution given:
the angles 2xº and 4yºare complementary
so
2x+4y=90°
dividing both side by 2we get
x+2y=45°
the value of x + 2y is 45°.
