Answers
Answer:
y = -x - 4
Step-by-step explanation:
m = y2-y1 / x2-x1
(-4, 0) and (1, -5)
m = -5+0 / 1+4
m = -5 / 5
m = -1
y = -x + b
0 = -(-4) + b
0 = 4 + b
b = -4
y = -x - 4

A = bh
A = 10×6
A = 60
A = 1/2h(b+b)
A = 1/2×12(10+20)
A = 6(30)
A = 180
180 + 60 = 240
240
Answer:
420 cm²
Step-by-step explanation:
Area of composite shapes
To calculate the area of a composite shape you must divide the shape into rectangles, triangles, or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes. Other composite shapes may have cut-out sections.Solve
To find the composite area of two or more shapes, simply find the area of each shape and add them together.
So,
18 cm × 20 cm = 360
10 cm × 6 cm = 60
Now, add the results together
360 + 60 = 420
Therefore, the area of the composite figure is 420 cm²

Jenny has overdrawn her bank account by $48.38. She makes a withdrawal of $10.25 and then makes a deposit of $60. What is the amount of money in Jenny's account after with withdrawal and deposit?
Answers
Over drawn means negative.
So she is at -43.38 then withdraws ( takes out) 10.25
Now her account is at -43.38-10.25 = -53.63
She than adds 60
Her final amount is -53.63 + 60 = $6.37
Answer:
-48.38-10.25= -58.63
-58.63 + 60= 1. 37

Step 3, the exponents of the same base are subtracted during division
Step 3, all the exponents are added during division

Step 1, all the exponents are increased by 4
Explanation:
The first incorrect step is Step 1 because you can add exponents during multiplication and subtract exponents during division. Step 3 didn’t happen at all because they subtracted the exponents when dividing
Sanjay surveyed 95 students at his school about their favorite class. Of the students surveyed, 19 said their favorite was Spanish. What is the experimental probability that the next student Sanjay talks to will pick Spanish?
Answers
Answer:
0.2 = 20% experimental probability that the next student Sanjay talks to will pick Spanish
Step-by-step explanation:
Probability:
A probability is the number of desired outcomes divided by the number of total outcomes.
It is called experimental when both these number of outcomes come from experiences, from a trial, as is the case in this exercise.
What is the experimental probability that the next student Sanjay talks to will pick Spanish?
19 out of 95. So
p = 19/95 = 0.2
0.2 = 20% experimental probability that the next student Sanjay talks to will pick Spanish

f(x) = 7x + 5
Answers
Answer:
-The function f translated 2 units down and 3 units right. > g(x)=7x-18
-The function f stretched vertically by a factor of 3 and translated up by 2 units. > g(x)=21x+17
-The function f stretched vertically by a factor of 2 and translated down by 3 units. > g(x)=14x+7
-The function f reflected about the y-axis and translated 3 units left. >g(x)=-7x-16
Step-by-step explanation:
-A function is shifted up or down when a constant is added outside the function. If the constant is positive the function is shifted up. If the constant is negative, the function is shifted down.
-A function is shifted left or right when a constant is subtracted from the x-value inside the function. If the constant is positive, the function is shifted to the right. If the constant is negative, the function is shifted to the left.
-A function is vertically stretched or compressed when it is multiplied by a constant. If the constant is greater than one, it results in a vertical stretch. If the constant is in between zero and one, it results in a vertical compression.
-A function is reflected about the y-axis when the x-value is multiplied by a negative constant.
Answer:
The function f stretched vertically by a factor of 3 and translated up by 2 units.
g(x)=21x+17
The function f translated 2 units down and 3 units right.
g(x)=7x-18
The function f reflected about the y-axis and translated 3 units left.
g(x)=-7x-16
The function f stretched vertically by a factor of 2 and translated down by 3 units.
g(x)=14x+7
Step-by-step explanation:
Functions can be moved and re-sized by changing the parameters of the function.
A function is shifted up or down when a constant is added outside the function. If the constant is positive the function is shifted up. If the constant is negative, the function is shifted down.
A function is shifted left or right when a constant is subtracted from the x-value inside the function. If the constant is positive, the function is shifted to the right. If the constant is negative, the function is shifted to the left.
A function is vertically stretched or compressed when it is multiplied by a constant. If the constant is greater than one, it results in a vertical stretch. If the constant is in between zero and one, it results in a vertical compression.
A function is reflected about the y-axis when the x-value is multiplied by a negative constant.

You need a 90% alcohol solution. On hand, you have a 55 mL of a 45% alcohol mixture. You also have 95% alcohol mixture. How much of the 95% mixture will you need to add to obtain the desired solution?
Answers
Answer:
495 milliliters of the 95% mixture are needed.
Step-by-step explanation:
Given that I need a 90% alcohol solution, and on hand I have a 55 ml of a 45% alcohol mixture, and I also have 95% alcohol mixture, to determine how much of the 95% mixture will I need to add to obtain the desired solution, the following calculation must be performed:
55 x 0.45 + 45 x 0.95 = 67.5
25 x 0.45 + 75 x 0.95 = 82.5
15 x 0.45 + 85 x 0.95 = 87.5
10 x 0.45 + 90 x 0.95 = 90
10 = 55
90 = X
90 x 55/10 = X
4,950 / 10 = X
495 = X
Thus, 495 milliliters of the 95% mixture are needed.
find the volume of the cone. Diameter:14 m, Slant Height:25 m
Answers
Answer:
1232m^3
Step-by-step explanation:
d = 14m
r = 7m
l = 25m
h = ?
h = root l^2- r^2
h = root 25^2- 7^2
h = root 625- 49
h = root 576
h = 24m
volume of cone = 1/3 pie r^2 h
= 1/3*22/7* 7*7*24
= 22*7*8
= 154*8
= 1232m^3
Answer:
1231.5 m³
Step-by-step explanation:
You have to find the height first.
using the Pythagoras rule,
hypotaneous² = base² + height²
25² = 7² + h²
576 = h²
h = √576
h = 24
Volume of cone = 1/3 π r² h
= 1/3 * π* 7² * 24
= 1231.5 m³

Find the coordinates of the point (x, y)
shown on the unit circle.
X=?
Y=?
Answers
Answer:
the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Step-by-step explanation:
The computation of the coordinates of the point is shown below:
The angle is
= 4π ÷ 3
The radius is 1 unit
Now
x = rcos[tex]\theta[/tex], and y = rsin[tex]\theta[/tex]
Now
x = 1cos(4π ÷ 3) = -1÷ 2
y = 1sin(4π ÷ 3) = -√3÷ 2
hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2

To test whether there is a difference between the group means of a sample ; the ANOVA test is employed ;
The appropriate hypothesis test:
The alternative hypothesis will habour the notion that there is a difference in sample means while the alternative will be opposite, that is, no difference exists in the sample means for the three treatments :
Null hypothesis ; H0 : μA = μB = μC ;
The alternative hypothesis, takes the opposite of the null ;
H1 : μA ≠ μB ≠ μC (this means that the mean values of the treatments are not the same
