Answer:
Day 13
Step-by-step explanation:
The question can be represented with a geometric sequence
Where,
a = 5
Common ratio , r = 2
v(t) = a * r^(t - 1)
v(t) = 5 * 2^(t-1)
20,000 = 5 * 2^(t-1)
Divide both sides by 5
20,000 / 5 = 5 * 2^(t-1) / 5
4,000 = 2^(t-1)
2^12 = 2^(t-1)
12 = t - 1
12 + 1 = t
t = 13 days
What would be the day when more than 20,000 people will see the video
Check:
v(t) = 5 * 2^(t-1)
= 5 * 2^(13-1)
= 5 * 2^12
= 5 * 4,096
= 20,480
Therefore,
The day when more than 20,000 people will see the video is day 13
Find the measure of the angle
Answer:
155°
Step-by-step explanation:
The angle between the x and y axes is 90°
The required angle = 90° + 65° = 155°
Answer:
Well, y is 90˚ and another angle is 65˚ that means that the unknown angle must be 25˚

The logo on a recycling bin resembles an equilateral triangle with side lengths of 6 centimeters. Approximate the area of the logo.
Answer:
9[tex]\sqrt{3}[/tex] cm² or approximately 15.59 cm²
Step-by-step explanation:
Use the formula for the area of an equilateral triangle, A = [tex]\frac{\sqrt{3} }{4}[/tex]a²
Plug in the side length, 6 cm, as a in the formula:
A = [tex]\frac{\sqrt{3} }{4}[/tex](6²)
A = [tex]\frac{\sqrt{3} }{4}[/tex](36)
A = 9[tex]\sqrt{3}[/tex]
So, the area of the logo is 9[tex]\sqrt{3}[/tex] cm² or approximately 15.59 cm²

Choose the correct answer for the problem
Answer:
D
Step-by-step explanation:
You would multiply the -5 and the -1 from the -5x^4 and the -x^5 this would make 5. Also the 4 and the 5 exponets, since they are exponets you need to add if multiplying so it would just be 4+5=9.
For y its just multiplying the exponets which is y^4xy^4=y^8.
Final answer if you bring everything together is 5x^9y^8 also answer D.

Find the area of the parallelogram.
Answer:
13.26cm^2
Step-by-step explanation:
[tex]\sqrt{18}+\sqrt{50}[/tex]
[tex]3\sqrt{2} +5\sqrt2}\\=8\sqrt{2}[/tex]
Answer:
8√2
Step-by-step explanation:
Both 18 and 50 are easily factorable, the first as 2*9 and the second as 2*25. Taking the square root of 18 results in 3√2 and that of 50 in 5√2/
Thus, the original problem √18 + √50 simplifies to (3 + 5)√2, or 8√2
f(x) = -1/2x^2 + 3/2x - 2 I need to find the zeros
Answer:
{-1, 4}
Step-by-step explanation:
In the given f(x) = -1/2x^2 + 3/2x - 2
set f(x) = 0 and then multiply all the numeric terms by -2 to remove the fractions:
f(x) = -1/2x^2 + 3/2x - 2 = 0 => 1x^2 - 3x - 4 = 0
This factors into (x - 4)(x + 1) = 0, whose roots are {-1, 4}. These are the zeros.

circle c shown below was dilated with the origin as the center of dilation to create circle C' which rule represents the transformation?
Answer:
A. (x, y) → (2/7x, 2/7y)Step-by-step explanation:
Equation of the smaller circle:
x² + y² = 2²Equation of the greater circle:
x² + y² = 7²The scale factor is the ratio of radiuses:
k = r₁ / r₂ = 2/7So the rule is:
(x, y) → (kx, ky) = (2/7x, 2/7y)Correct choice is A
Answer:
[tex]\sf A. \quad (x, y) \rightarrow \left(\dfrac{7}{2}x, \dfrac{7}{2}y \right)[/tex]
Step-by-step explanation:
The distance from the center of the circle to any point on the circumference is the radius.
From inspection of the given graph:
Radius of Circle C (before dilation) = 2 unitsRadius of Circle C' (after dilation) = 7 unitsTo find the scale factor of the dilation from the small circle C to the large circle C', divide the radius of the large circle by the radius of the small circle.
Therefore, the dilation is an enlargement of scale factor ⁷/₂ about the origin.
So the rule that represents the transformation is:
[tex]\sf (x, y) \rightarrow \left(\dfrac{7}{2}x, \dfrac{7}{2}y \right)[/tex]
Check (see attached):
Point (0, 2) is on circle C.
[tex]\implies \sf (0, 2) \rightarrow \left(\dfrac{7}{2}(0), \dfrac{7}{2}(2) \right)=(0,7)[/tex]
Point (1, √3) is on Circle C:
[tex]\implies \sf (1, \sqrt{3}) \rightarrow \left(\dfrac{7}{2}(1), \dfrac{7}{2}(\sqrt{3}) \right)=\left(3.5,6.06)[/tex]
Stella is running a bakery. She has made a street sign to direct people to her bakery. She painted one side of the post and sign. What is the painted area. 75, 8, 12, 12, 4 1. 11 2. 13 3. 21 4. 4
Answer:
768 square inches
Step-by-step explanation:
Area of the rectangle = length × width
Length = 75 in
Width = 12 in
Area of the rectangle = length × width
= 75 in x 8 in
= 600 in²
Area of the square = length ²
Length = 12 in
Area of the square = length ²
= 12 in²
= 12 in × 12 in
= 144 in²
Area of a triangle = 1/2bh
b = base = 12 in
h = height = 4 in
Area of a triangle = 1/2bh
= 1/2 * 12 in * 4 in
= (1*12*4)in² / 2
= 48 in² / 2
= 24 in²
Total area of the painted part of the street sign = Area of the rectangle + Area of the square + Area of a triangle
= 600 in² + 144 in² + 24 in²
= 768 in²
The area of a trapezoid is found using
the formula A=12 h(b1+b2), where A is
the area, h is the height, and b1 and
b2are the lengths of the bases. What
is the area of a trapezoid with the
height of 12, b = x +1, and b = x + 3?
Answer:
288x+576
Step-by-step explanation:
A=12×h(b1+b2)
A=12×12(x+1+x+3)
A=144(2x+4)
A=288x+576

Answer:
B, C, D, and F are all possible.
Answer:
B, C, D
Step-by-step explanation:
1. A is not possible because right and obtuse both define triangle angles. An angle cannot be obtuse and right at the same time.
2. B is possible because a right triangle can have all sides of different length.
3. C is possible because a scalene triangle can have an obtuse angle.
4. D is possible because an isosceles triangle can have all acute angles.
5. E is not possible because of how equilateral triangles work. When a triangle is equilateral, it is also equiangular, meaning all of its angles are the same. The angles on every type of triangle always add up to 180 degrees. If a triangle is equiangular, the 180 degrees are divided evenly, with every angle being 60 degrees, which is acute. Therefore, an equilateral triangle cannot have a right angle.
6. F is not possible because isosceles and scalene both refer to the side lengths of triangles. A triangle cannot be isosceles and scalene at the same time.
7. G is not possible because equilateral triangles cannot have angles other than 60 degrees and therefore cannot be obtuse.
Determine the domain of the following graph
Answer:
Step-by-step explanation:
1) The domain is related to the behaviour of the x
the graph started when x is -11 and finish when x is 1
so
D : [-11 ; 1]
or -11 ≤x ≤ 1
the range is related to the behavior of y
the graph start when y is -7 and finish when y = 0
Range : [-7;0]
or -7≤ y ≤ 0
Use technology or a z-distribution table to find the indicated area.
The masses of the eggs collected on a farm are normally distributed with a mean of 55 grams and a standard deviation of 4.2 grams.
Approximately 80% of the eggs on the farm have a mass greater than which mass?
51.5 g
54.1 g
55.8 g
58.5 g
Answer:
51.5g or A
I took a test with this question and got it right
Using the normal distribution, it is found that approximately 80% of the eggs on the farm have a mass greater than 51.5 g.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 55, \sigma = 4.2[/tex].
Approximately 80% of the eggs on the farm have a mass greater than the 20th percentile, which is X when Z = -0.84, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.84 = \frac{X - 55}{4.2}[/tex]
X - 55 = -0.84 x 4.2
X = 51.5 g.

14.) 20
15) 16
16) true
Answer:
20, 16, true
Step-by-step explanation:
The input is the number of rides, or the x-coordinate. The output is the dollars remaining on card, or the y-coordinate. We know this because the number of rides dictates how much money is on the card.
14. The question is asking for the output when the input is ten. Thus, we need to find the y-coordinate on the line when the x-coordinate is 10. We see that (10,20) is on the line, so then our output (or y-coordinate) is 20.
15. The question is asking for the input when the output is five. Thus, we need to find the x-coordinate on the line when the y-coordinate is 5. We see that (16,5) is on the line, so then our input (or x-coordinate) is 16.
16. 7 rides is the x-coordinate, and 27.50 is the cost, or the y-coordinate. However, this is true because even though the y-coordinate is NOT the cost of the rides, but the amount of money remaining on the card AFTER the rides are cashed in, 27.50 is half of 45 dollars, so then if 27.50 is spent on the rides, there will still be 27.50 left over on the card. Thus, it is true.
