Answer:
[tex]y=9x-13[/tex]
Step-by-step explanation:
Slope-intercept form is [tex]y=mx+b[/tex], where m is the slope, and b is the y-intercept. They tell us the slope is 9, so [tex]m=9[/tex]. They also tell us that the y-intercept is (0,-13), which means that [tex]b=-13[/tex]. Plugging both of those values in gives us the equation:
[tex]y=9x-13[/tex]

I need a reason for both
9514 1404 393
Answer:
23) insufficient number of corresponding sides/angles
24) insufficient number of corresponding sides/angles
Step-by-step explanation:
In general, you need at least 3 corresponding parts to show triangle congruence. At least one of those must be a side. The attachment shows the ways triangles can be declared congruent. (HL works for right triangles, because we know the right angles are congruent to each other.)
__
23) A side is shown congruent (KL ≅ GH), and we know the vertical angles at J are congruent. However, we need another angle before we can declare the ∆GHJ congruent to anything. (One more side doesn't do it, because the two sides would not be on either side of the angle at J.)
Reason: insufficient data
__
24) A side is shown congruent (MP ≅ QS), and an angle is shown congruent (∠M ≅ ∠Q). As in the previous problem, we need at least one more angle, or we need to know that MN ≅ QR before we can declare the triangles congruent.
Reason: insufficient data
Gavin, Colin and Dan share some sweets in the ratio 4:5:3. Gavin gets 20 sweets. How many sweets are there altogether?
9514 1404 393
Answer:
60
Step-by-step explanation:
Gavin has 20/4 = 5 times as many sweets as his corresponding number of ratio units. The total number of ratio units is 4+5+3 = 12, so the total number of sweets is 5×12 = 60.
There are 60 sweets altogether.

a circle centered ar the the orgin has a radius of 1/2 what is the equation of the circle
Answer:
The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Centered at the the origin
Center (0,0), which means that [tex]x_0 = 0, y_0 = 0[/tex]
radius of 1/2
This means that [tex]r = \frac{1}{2}[/tex]
Equation:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - 0)^2 + (y - 0)^2 = (\frac{1}{2})^2[/tex]
[tex]x^2 + y^2 = \frac{1}{4}[/tex]
The equation of the circle is [tex]x^2 + y^2 = \frac{1}{4}[/tex]
Let f open parentheses x close parentheses equals ln open parentheses x squared close parentheses space space space a n d space space space g open parentheses x close parentheses equals square root of e to the power of 3 x end exponent end root. Find f o g open parentheses x close parentheses and its domain?
Answer:
[tex](f\ o\ g)(x) = 3x[/tex]
[tex]-\infty < x < \infty[/tex]
Step-by-step explanation:
See comment for right presentation of question
Given
[tex]f(x) = ln(x^2)[/tex]
[tex]g(x)=\sqrt{e^{3x}}[/tex]
Solving (a): (f o g)(x)
This is calculated as:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
We have:
[tex]f(x) = ln(x^2)[/tex]
[tex]f(g(x)) = \ln((g(x))^2)[/tex]
Substitute: [tex]g(x)=\sqrt{e^{3x}}[/tex]
[tex]f(g(x)) = \ln(\sqrt{e^{3x}})^2[/tex]
Evaluate the square
[tex]f(g(x)) = \ln(e^{3x})[/tex]
Using laws of natural logarithm:
[tex]\ln(e^{ax}) = ax[/tex]
So:
[tex]f(g(x)) = \ln(e^{3x})[/tex]
[tex]f(g(x)) = 3x[/tex]
Hence:
[tex](f\ o\ g)(x) = 3x[/tex]
Solving (b): The domain
We have:
[tex]f(g(x)) = 3x[/tex]
The above function has does not have any undefined points and domain constraints.
Hence, the domain is: [tex]-\infty < x < \infty[/tex]

A small pond contains 8 catfish and two bluegill. If eight fish are caught at random what is the probability that all of them are catfish
Find the area of these figures
Answer:
I think the answer for the first one would be 32^2 meters for 4m × 4m and 13m. The 6m and 8m would be 48^2 meters. The second one would be 5in × 5in would be 25in and 2in × 4in would be 8in. The third one would be 6ft × 6ft × 6ft would be 48ft.
Step-by-step explanation:
To find area, you have to multiply the sides of each figure.
A = a^2 = 4m × 4m × 13m = 32.A = a^2 = 6m × 8m = 48.5 × 5 = 25.2 × 4 = 8.6 × 6 = 36 + 12 = 48.I hope this helps your question!

Step-by-step explanation:
A cross section is the intersection between a (three dimensional figure) and also a (plane).
When an object is being cut straight, the shape that we get is referred to as the cross section. We should note that several parallel cross sections will be firmed when we cut a particular object into slices.
The function f(x) is a quartic function and the zeros of f(x) are -4,-3,2 and 5. Assume the leading coefficient of f(x) is 1. Write the equation of the quartic polynomial in standard form
The equation of the quartic polynomial in standard form is,
⇒ f (x) = x⁴ - 27x² - 14x + 120
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
We have to given that;'
The function f(x) is a quartic function and the zeros of f(x) are -4,-3,2 and 5.
And, the leading coefficient of f(x) is 1.
Hence, We get;
The equation of the quartic polynomial in standard form is,
⇒ f (x) = 1 (x - (- 4)) (x - (- 3)) (x - 2) (x - 5)
⇒ f (x) = (x + 4) (x + 3) (x - 2) (x - 5)
⇒ f (x) = (x² + 7x + 12) (x² - 7x + 10)
⇒ f (x) = x⁴ - 7x³ + 10x² + 7x³ - 49x² + 70x + 12x² - 84x + 120
⇒ f (x) = x⁴ - 27x² - 14x + 120

Find the area of the complex figure.
Answer:
1,863
Step-by-step explanation:
As part of a study of corporate employees, the director of human resources for PNC, Inc. wants to compare the distance traveled to work by employees at its office in downtown Cincinnati with the distance for those in downtown Pittsburgh. A sample of 40 Pittsburgh employees showed they travel a mean of 370 miles per month. A sample of 35 Cincinnati employees showed they travel a mean of 380 miles per month. Do the Cincinnati employees travel the same distance to work, on average, as the Pittsburgh employees
Answer:
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
Step-by-step explanation:
40 Pittsburgh employees mean travel time = 370 miles
35 Cincinnati employees mean travel time = 380 miles
Both groups of Employees do not travel the same distance to work hence we will reject the Null hypothesis
H0 : μ1 = μ2
H1 : μ1 ≠ μ2
mean = total distance / Number of employees
For Pittsburgh
370 = x / 40
x = 370 * 40 = 14,800 miles
For Cincinnati
380 = y / 35
y = 380 * 35 = 13,300 miles

Step-by-step explanation:
At a high school with over 500 students, a counselor wants to estimate the mean number of hours per week that students at the school spend in community service activities. The counselor will survey 20 students in the Environmental Club at the school. The mean number of hours for the 20 students will be used to estimate the population mean. Which of the following conditions for inference have not been met?
1. The data are collected using a random sampling method.
2. The sample size is large enough to assume normality of the distribution of sample means.
3. The sample size is less than 10 percent of the population size.
Complete option:
The sample size is less than 10 percent of the population size. A. II onlyB. III onlyC. II and III onlyD. I, II, and III
Answer:
D.) I, II, and III
Step-by-step explanation:
The sample are not well randomly selected as the samples were only selected from a single source, the environmental club in the school.
Similarly only 20 samples were chosen, these 20 samples are not enough to assume normality as the minimum number of samples required to assume normality according to the Central limit theorem is 30 samples or more.
10% of the population size is :
Population size = 5000
0.10 * 5000 = 500 samples
Hence, sample size used is less than 10% of population size.

Help please I need to complete this before 12
Answer:
Look at the answers bolded below
Step-by-step explanation:
To get the reference angle, just subtract 115° from 180°
180 - 115 = 65
So the reference angle is 65°
I'm not sure how many coterminal angles you need, but to get them you could just add or subtract 360°.
For example, a positive coterminal angle could be:
115 + 360 = 475°
a negative coterminal angle could be:
115 - 360 = -245°
Hope this helped :)

17. Stella is competing in a diving competition. Her height in feet above the water is
modeled by the function h=-16t? + 8t + 48, where t is the time in seconds after she jumps
from the diving board. At what time will Stella land in the water? (Round to the nearest
hundredth, if necessary.)
9514 1404 393
Answer:
after 2 seconds
Step-by-step explanation:
We want to find t such that h = 0.
0 = -16t² +8t +48
0 = 2t² -t -6 . . . . . . . divide by -8
0 = (t -2)(2t +3) . . . . factor
The only positive solution is t = 2, which makes the first factor zero.
Stella will land in the water at t = 2 seconds.
