Use the diagram shown. BD is the perpendicular blsector of AC.
AD is 10 Inches long. BD is 6 inches long. Find the length of AC.
D
A
B
AC =
in.
Answer:
AC = 16 in.
Step-by-step explanation:
AD = CD = 10 in.
BD = 6 in.
AC = 2(AB) = ?
Apply pythagorean theorem to find AB
AB² = AD² - BD²
Substitute
AB² = 10² - 6²
AB² = 64
AB = √64
AB = 8
Therefore:
AC = 2(AB) = 2(8)
AC = 16 in.

The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)+2.
Which statement about the graphs is true?
The vertex of the graph of g is 2 units above the vertex of the graph of f.
The vertex of the graph of g is 3 units to the right of the vertex of the graph of f.
The vertex of the graph of g is 2 units below the vertex of the graph of f.
The vertex of the graph of g is 2 units to the left of the vertex of the graph of f.
Answer:
The vertex of the graph of g is 2 units above the vertex of the graph of f.
Step-by-step explanation:
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x). Then the correct option is A.
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The graph of f(x) = x² was transformed to create a graph g(x) =f(x)+2.
Then the g(x) will be
g(x) = x² + 2
We know that the graph of the g(x) shifted to 2 units upward because we added 2 in the function.
The graph is shown.
The vertex of the graph of g(x) is 2 units above the vertex of the graph of f(x).
Thus, the correct option is A.

In January, the ratio of the number of butterflies to the number of bees in a garden was 7 : 3. In February, the butterfly population decreased by 20% while the bee population increased by 30%.
(a) What was the percentage change in the combined butterfly and bee population?
(b) If there were 168 butterflies left in February, what was the butterfly population in January?
Answer:
a) The percentage change in the combined butterfly and bee population was a decrease of 5%.
b) The butterfly population in January was 210.
Step-by-step explanation:
In January, the ratio of the number of butterflies to the number of bees in a garden was 7 : 3.
This means that:
[tex]\frac{x}{y} = \frac{7}{3}[/tex]
In which x is the number of butterflies and y is the number of bees.
In February, the butterfly population decreased by 20% while the bee population increased by 30%.
This means that:
[tex]\frac{x}{y} = \frac{7*(1-0.2)}{3*(1+0.3)} = \frac{7*0.8}{3*1.3} = \frac{5.6}{3.9}[/tex]
(a) What was the percentage change in the combined butterfly and bee population?
January: 7 + 3 = 10
February: 5.6 + 3.9 = 9.5
Change
[tex]100*\frac{9.5-10}{10} = -\frac{50}{10} = -5[/tex]
This means that the percentage change in the combined butterfly and bee population was a decrease of 5%.
(b) If there were 168 butterflies left in February, what was the butterfly population in January?
February is 80% of January, for the population of butterflies. So
[tex]0.8x = 168[/tex]
[tex]x = \frac{168}{0.8}[/tex]
[tex]x = 210[/tex]
The butterfly population in January was 210.
Using the net below, find the surface area of the triangular prism .
Don’t try scamming me
Answer:
Surface area = 528 cm²
Step-by-step explanation:
The net of the prism is composed of 2 equal triangles and 3 rectangles (only 2 are of the same dimensions)
Area of the 2 triangles:
Area of the 2 triangles = 2(½*bh)
= 2(½*6*8)
= 6*8
= 48 cm²
Area of the 2 equal rectangles:
Area = 2(L*W)
L = 20
W = 9
Area of the 2 equal rectangles = 2(20*9)
= 360 cm²
Area of the 3rd rectangle:
Area = L*W
L = 20
W = 6
Area = 20*6 = 120 cm²
✔️Surface area of prism = 48 + 360 + 120 = 528 cm²
In ΔJKL, k = 490 cm, l = 830 cm and ∠J=49°. Find ∠L, to the nearest degree.

This table shows the cost of renting a kayak.
Hours Cost
1. $13
2. $21
3. $29
4. $37
5. $45
The cost of renting a kayak is represented by the equation
y = 8x + 5, where x represents the number of hours. What
does the slope of the equation represent?
9514 1404 393
Answer:
dollars per hour
Step-by-step explanation:
If m is the slope, the units of m can be found by considering the units of x and y.
y is in dollars
x is in hours
Then from the point of view of units, we have ...
dollars = m × hours
m = dollars/hours
The slope in the equation is the rental charge in dollars per hour.

Use the Law of Cosines to find angle round to the nearest tenth if necessary).
Answer:
Step-by-step explanation:
3a)
find side HP , let's set side HP = c in the law of cosines formula
then
c = sq rt [ 23^2 + 12^2 - 2*12*23*cos(117) ]
c = sq rt [ 529 + 144 - (-250.6027559) ]
c = sq rt [ 673 + 250.6027559 ]
c = sq rt [ 923.602755 ]
c = 30.39
then
HP = 30.4 ( rounded to nearest 10th )
3b)
let PR = c, then law of cosines is (we need angle Q also 180=24+97+Q is 59°
c = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
c = sq rt [ 81 + 484 -396*0.5150380 ]
c = sq rt [ 565 - 203.955 ]
c = sq rt [ 391.04495]
c = 19.7748
PR = 19.8 ( rounded to nearest 10th )
3c)
they want us to find ∠B, in the formula for cosines ∠B is really ∠C, it's a bit confusing.. I'm sure they did that on purpose to mess people up. Kind of underhanded :/ Tell the teacher that you're "appalled" at the deviousness of the test :/ stage a protest against math that teaches treachery :P storm the principals/ dean's office with paper airplanes and pictures of anime :DDD okay back to math.
a=28
b=17
c=15
since we want angle B then the formula looks like
B= arcCos ( a^2 + c^2 - b^2 / 2*a*c) so we'll avoid messing up the which side is which ... by setting up the formula this way .. got it?
B = arcCos [28^2 + 15^2 - 17^2 / 2*28*15]
B = arcCos[784 + 225 - 289 /840 ]
B = arcCos[720/ 840]
B = arcCos[0.85714285]
B = 31.0027 °
that it came out so close to an integer I'm pretty sure it's right
∠B = 31 .0 ° ( rounded to the nearest 10th )
3d)
find ∠A
set it up carefully again, they are asking us to move the variable around again
a = 18
b= 28
c= 12
then the formula looks like
∠A = arcCos[ b^2 + c^23 - a^2 / 2*b*c ]
∠A = arcCos[28^2 + 12^2 - 18^2 /2*28*12 ]
∠A = arcCos[784 + 144 -324 / 672 ]
∠A = arcCos[604/672]
∠A = arcCos[0.8988095]
∠A =25.99797 °
∠A =26.0 ° ( rounded to nearest 10th)

Find the equation of the parabola whose vertex is the origin and whose directrix is x = -4
Try this option:
1) if V(0;0) and x= -4, then common view of the required equiation is:
(y-k)²=4p(x-h), where focus is in (h-p;k), the vertex is in (h;k), the directrix is x=h+p, p<0 and y=k is simmetry axis;
2) if the V(0;0), then h=k=0 and the required equiation is:
y²=4px;
3) if the directrix equation is x=h+p, where h=0, then p= -4 (according to the condition the directrix equation is x= -4), then the required equation is:
y²= -16x
answer: y²= -16x

A movie theatre charges adults $10 to see a movie and charges children $6. If there wereq 120 people who saw a movue and the theatre collected $928, home many attendees were adults
Answer:
The number of adults tickets sold equals 52.
Step-by-step explanation:
First, we need to establish the system of equations:
x= number of adults tickets sold
y= number of kids tickets sold
10x + 6y= 928
x + y=120
Now, we isolate x in one equation and change it in the other to obtain its value:
x= 120 - y
10(120 - y) + 6y = 928
1,200 - 10y + 6y = 928
272 = 4y
68 = y
x= 120 - 68= 52

The volume of a hemisphere with a radius of 5.7 m is 193.83534 m³.
What is Volume?Volume is a mathematical term used to describe how much three-dimensional space an item or closed surface occupies. Volume is measured in cubic units like m3, cm3, in3, etc.
Volume is sometimes referred to as capacity.
We have,
Radius = 5.7 m
So, the Volume of Hemisphere
= 2/3 πr³
= 2/3 x 3.14 x (5.7)³
= 2/3 x 3.14 x 185.193
= 193.83534 m³
Thus, the volume is 193.83534 m³.
