Questions:
1) What is the vertex?
2) What is the axis of symmetry?
3) What are the x-intercepts?
4) What are the y-intercept?
5) What is the ordered pair symmetric to the point (-1,-5)?
Answer:
Below.
Step-by-step explanation:
1. Vertex is (1, -9)
2. Axis of symmetry is x = 1.
3. x-intercepts are at (-2,0) and (4,0).
4. y-intercept is at (0, -8).
5. That is (3, -5).
Answer:
Vertex: In the geometry of plane curves, a vertex is a point of where the first derivative of curvature is zero. This is typically a local maximum or minimum of curvature, and some authors define a vertex to be more specifically a local extreme point of curvature.
The axis of symmetry of a parabola is a line about which the parabola is symmetrical. When the parabola is vertical, the line of symmetry is vertical. When a quadratic function is graphed in the coordinate plane, the resulting parabola and corresponding axis of symmetry are vertical.
The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.
Y-intercept: In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system. As such, these points satisfy x = 0.

Determine the slope of the line that passes through each pair of points. Write in simplest form. (3,8) and (1,5)
Answer:
y = 3/2x + 7/2
Step-by-step explanation:
First, you need to find the slope.
y2 - y1 / x2 - x1
= 5 - 8 / 1 - 3
= 3/2
The slope is 3/2x.
To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b
y = 3/2x + b
8 = 3/2(3) + b
8 = 9/2 + b
7/2 = b
The equation y = 3/2x + 7/2.

Find the expected value and standard deviation.
Answer:
1) E(X) = 1.5
2)SD = 1.118
Step-by-step explanation:
1) Formula for expected value of this set of data is;
E(X) = Σx * P(x)
Σx = 0 + 1 + 2 + 3 = 6
And P(x) = ¼
Thus;
E(X) = 6 × ¼ = 1.5
2) Formula for the standard deviation is;
SD = √Σ((x - μ)²•P(x))
Where μ is the expected value = 1.5
At x = 0,we have;
(0 - 1.5)² × 1/4 = 0.5625
At x = 1, we have;
(1 - 1.5)² × 1/4 = 0.0625
At x = 2, we have;
(2 - 1.5)² × 1/4 = 0.0625
At x = 3, we have;
(3 - 1.5)² × 1/4 = 0.5625
Thus,Σ((x - μ)²•P(x)) = 0.5625 + 0.0625 + 0.0625 + 0.5625 = 1.25
Thus;
SD = √1.25
SD = 1.118
if you cycled for 3 hours and travelled 54 km calculate your average speed
Answer:
162 km per hour
Step-by-step explanation:
Hi!
Speed=Distance x Time
So... 3 x 54 = 162
Hope this helps :)
Answer:
18km/h
Step-by-step explanation:
Well. Speed = Distance x Time
So if she travelled for 3 hours. In that time, she must have travelled 54km.
Average speed is given as kilometres per hour or km/h
So all we need to do is 54/3 which gives us 18km/h

Answer:
1.) isosceles
2.) equilateral
3.) obtuse
4.) right
help please! find m∠bcf
Answer:
BCF = 140°
See attached image.
Answer:
m<BCF=140°
Step-by-step explanation:
first find m<BCD
m<BCD=180-50-90
m<BCD=40°.
to find m<BCF, we can do 180-m<BCD, since m<BCD and m<BCF add up to 180° (they form a straight angle)
180-m<BCD=m<BCF
180-40=m<BCF
m<BCF=140°

How much should a retailer mark up his goods so that when he has a 50% off sale, the resulting prices will reflect prices will still reflect a 75% markup, (on his cost)
Answer:
250%
Step-by-step explanation:
Let initial Markup % = x
Sales price = 100% + x = (1 + x)%
50% off sale = (1+x)% - (1+x)% /2
Final price after 50% off sale = 1 + 0.75 = 1.75
Hence,
50% off sale = 75% price markup
0.5(1 + x) = 1.75
0.5 + 0.5x = 1.75
0.5x = 1.75 - 0.5
x = 1.25 / 0.5
x = 2.5
Hence, Markup on initial price should be 1.25 = (2.5 * 100%) = 250%
Lyle sliced a block of cheese along a diagonal into two triangular prisms as shown. Lyle says that the surface area of the block is 2 times the surface area of one of the triangular prisms. Do you agree? Explain your answer This is followed by: Refer to problem 5. Find the difference between the surface area of the two triangular prisms and the surface area of the surface area of the rectangular prism. Show your work. Help now plz!!!
Answer:
Step-by-step explanation:
I have attached an image to make question clearer.
(A) Yes, the surface area of the block is twice the surface area of one of the triangular prisms. This is because the block has opposite faces to be equal since it's a cuboid, also all it's faces to be made of rectangles, therefore cutting it from the diagonal makes two equal triangles. Hence, the two triangular prisms are the same and since they are the same, two of the prisms will make up the block again. In conclusion, the surface area of the block will be times two of one of the triangular prism's surface area.
(B) since the surface area of the block is times two of the surface area of the triangular prism. Then we should look for the area of the prism.
Surface area of cuboid is given as:
2(L x W + L x H + W x H)
L = 4.5, W = 3 and H = 4.
Surface area = 2(4.5*3 + 4.5*4 + 3*4) = 87
Since the surface area is 87, then the surface area of one of the two triangles will be
87/2 = 43.5.

Ben put $6,500 into a savings account that earns 2.5% interest each year. How much interest will he earn after 6 years in the savings account?
Answer:
$1,038
Step-by-step explanation:
the equation for annual compound interest is y=p(1±r)^t, where p is the principal (starting amount), r is the rate (as a decimal), and t is the number of years (time).
2.5% as a decimal is 0.025
We will add that to 1, because when we earn interest, we are gaining money.
So we will substitute our given numbers into the equation:
y=6500(1.025)^6
solve:
y=$7,5638 (rounded)
That's the total amount he earned (principal + interest). To find out how much interest he earned over those 6 years, subtract our new amount from our starting amount
75638-6500
$1,038
So he made $1,038 in interest

Ms. Wang and her class are selling bags of cookies to raise money for a field trip.
Each bag weighs 140 grams and has 6 cookies.
Each cookie has the same amount of dough that weighs 14 grams.
Each cookie has the same amount of candy
If a bag of candy has 20 grams of Candy, how many bags of candy does the class need to make 18 cookies?
Answer:
9 bags of candy
Step-by-step explanation:
6 cookies at 14 grams each = 84 grams meaning the remaining grams of the 140 have to be the weight of the candy which = 56 grams (140-84). To find out how much candy is in one cookie divide 56 by 6 which = 9.33333. You then divide 20 by 9.3333 which = 2.14 (rounded to nearest 10th). Since you can get just over 2 cookies worth of candy per bag you only need half the number of cookies in bags of candy (9 bags)

While in the blueprint, each square is 1/4...in real life, it's 4 feet per square.
Meaning, the area of each square is (4 x 4) 16 square feet.
Since there are 8 squares/tiles in the bathroom...
...multiply 8 x 16 = 128 square feet in real life.
Multiply that with the cost, and since it costs $5 per square feet:
128 x 5 = $640 (answer)For b.
Do it in similar steps.
Living room: 4 x 7 = 28 tiles
Bedroom: 4 x 5 = 20 tiles
20 + 28 = 48 tiles (in blueprint)
...multiply 48 x 16 = 768 feet square (in real life)
[Convert feet into yards...3 feet equals 1 yard]
a square yard would be 3 feet x 3 feet = 9 feet...
...divide 768 by 9
768 ÷ 9 = 85.33 square yards (rounded up)
Multiply that with the cost, and since it costs $18 per square feet:
85.53 x 18 = $1535.94 (answer)
