Write the equation of the line that is perpendicular to the line 5y=x−5 through the point (-1,0).
Answers
Hey there!
First, we want to put the equation of this first line in slope-intercept form.
5y=x-5
We divide both sides by 5.
y=1/5x-1.
The slope of a perpendicular is line is the negative reciprocal of the slope of the original line. The slope of a line perpendicular to a line with the equation y=1/2x would be -2, because you flip the numerator and denominator and then make it negative.
So, this means that the slope of the line perpendicular to the line y=1/5x-1 is -5. So, here's our equation so far.
y= -5x+b
Now, we need to find the b. To do this, we can plug in this point (-1,0) that this perpendicular line goes through and solve for b.
0=-5(-1)+b
0=5+b
b= -5
So, this gives us the equation y= -5x-5

Around which line would the following cross-section need to be revolved to create a sphere? circle on a coordinate plane with center at 1 on the y-axis and a radius of 1
Answers
Answer:
y= 1
Step-by-step explanation:
A circle forms a sphere only when it goes around a straight line throughout the center so y= 1 because it's (1,0).
The y = 1 is the axis around which the circle cross-section needs to be revolve to create a sphere.
It is given that the circle is on a coordinate plane with the centre at 1 on the y-axis.
It is required to find around which line would the following cross-section need to be revolved to create a sphere.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the centre of a circle).
We have a circle on the coordinate plane the centre of the circle lies on the y-axis at 1.
On y=axis the value of x is zero ie. x= 0
The centre of the circle = (0,1)
If a half-circle revovle around the axis which is dividing the circle into two halves.
As we can see in the graph the y-axis and y=1 divide the circle into two halves.
Thus, the line y = 1 is the axis around which the circle cross-section needs to be revolve to create a sphere.

Assume that an opinion poll conducted in a 1998 congressional race found that on election eve, 54% of the voters supported Congressman Stevens and 44% supported challenger Jones. Also assume that the poll had a +/- 3% margin of error. What would the pollster be able to safely predict?
Answers
Answer:
Congressman Stevens will win the race
Step-by-step explanation:
Considering the margin of error, the possible outcomes for each candidate would be:
Congressman Stevens: from (54 - 3)% to (54+3)%
Challenger Jones: from (44 - 3)% to (44+3)%
Congressman Stevens: from 51% to 57%
Challenger Jones: from 41% to 47%
Therefore, even considering the margin of error, the pollster would be able to safely predict that Congressman Stevens will win the race.
The graph of g(x) resembles the graph of f(x)=x^2, but it has been changed. Which of these is the equation of g(x)?
Answers
Answer:
A.
Step-by-step explanation:
Anwer A has the following equation:
[tex]g(x)=\frac{3}{5}x^2-3[/tex]
In this equation, we can calculated the intercept replacing x by 0, as:
[tex]g(x)=\frac{3}{5}0^2-3=-3[/tex]
if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.
Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:
[tex]0=\frac{3}{5}x^2-3\\x_1=\sqrt{5}=2.236\\x_2=-\sqrt{5}=-2.236[/tex]
It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.
So, the answer is A, [tex]g(x)=\frac{3}{5}x^2-3[/tex]

C. y = -2(x - 4)
y = -2x + 8 incorrect
D. y = -(-2x+8)
y = 2x - 8 incorrect
y = -2x - 8 and y = -(2x + 8) when graphed are the same, they intersect at infinite points and there are infinite solutions.

Carmen received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.44 per pound. After buying the coffee, she had $37.80 left on her card. How many pounds of coffee did she buy?
Answers
Answer:
Carmen bought 5 pounds of coffee
Step-by-step explanation:
The cost of buying coffee is $8.44 per pound. Let us assume she bought x pound of coffee, this means that she spent $8.44x on coffee.
She went to the coffee store with $80 gift card and left with $37.80, this means that after spending $8.44x from the initial $80, she had $37.80. To find the number of pounds she bought, we are to use the following equation:
80 - 8.44x = 37.80
8.44x = 80 - 37.80
8.44x = 42.2
x = 42.2/ 8.44 = 5
x = 5 pounds.

If she wants to carry more than 3 times as many of the smaller boxes, what is the maximum number of larger boxes that she can fit in the van? A) 15 B) 16 C) 17 D) 18
Answers
Answer: C) 17
Step-by-step explanation:
Let x be the number of large boxes
As per given,
Number of small boxes= 3 × (number of large boxes)
i.e. Number of small boxes= 3x
Allie is transporting boxes of two sizes: 12 cubic feet and 5 cubic feet.
Total volume = 12 (number of large boxes) + 5(Number of small boxes)
= 12 x+ 5 (3x)
= 12x+15x
= 27x
A moving van’s cargo area has a maximum volume of 480 cubic feet.
[tex]\Rightarrow\ 27x \leq480[/tex]
Divide both sides by 27 , we get
[tex]x\leq17.78[/tex]
i.e. maximum value x can take = 17
So, the maximum number of larger boxes that she can fit in the van = 17.

What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
A sequence is defined by the formula,
⇒ f (n+1) = f(n) - 3
Now, We can find the value of f (1) as;
Here, f (4) = 22
Put n = 3;
⇒ f (n+1) = f(n) - 3
⇒ f (3+1) = f(3) - 3
⇒ f (4) = f (3) - 3
⇒ 22 = f (3) - 3
⇒ 22 + 3 = f(3)
⇒ f(3) = 25
Put n = 2;
⇒ f (2+1) = f(2) - 3
⇒ f (2+1) = f(2) - 3
⇒ f (3) = f (2) - 3
⇒ 25 = f (2) - 3
⇒ 25 + 3 = f(2)
⇒ f(2) = 28
Put n = 1;
⇒ f (n+1) = f(n) - 3
⇒ f (1+1) = f(1) - 3
⇒ f (2) = f (1) - 3
⇒ 28 = f (1) - 3
⇒ 28 + 3 = f(1)
⇒ f(1) = 31

Kelly needed to use 3 pounds 15 ounces of clay to make a bowl and twice as much to make a vase. If she had a 12-pound bag of clay available, did she have enough clay to make both items?
Answers
Answer:
yes
Step-by-step explanation:
so first you would convert pounds into ounces (It's easier for me)
and there are 16 ounces in one pound so for 3 pounds you would have 48 ounces then add the 15 ounces to get 63 ounces and if she needs twice as much to make a vase she would need 126 ounces for a vase then you would add the other 63 to that to get a total of 189 ounces of clay in order to create the bowl and vase, and in order to find out how many ounces are in a 12 pound bag you would just multiply 12 by 16 to get 192 ounces. So yes she does have enough clay to make a bowl and a vase.
