Heather is training for a long-distance run. Her data points listed below represent the days of practice, x, and the
number of miles run, y.
(1, 2.5), (2, 4.2), (4,5.6), (6, 7), (8, 8.1), (10, 11)
Use the equation to interpolate the value and estimate the distance that she could have run on day 3. Round to the
nearest tenth of a mile.

day 3
Answer:
4.6
Step-by-step explanation:
The distance run on day 3 is about 5.9 miles.
What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
The data points given are:
(1,2.5), (2,4.2), (4.5,6), (6,7), (8,8.1), (10,11)
Note that the growth seems to be linear, therefore, find a linear equation for the data.
Use (1,2.5) and (2,4.2) to find the slope of the line:
m = (4.2-2.5)/(2-1)
m = 1.7
The equation of the line with slope m = 1.7 and passes through point (1, 2.5) is:
y - 2.5 = 1.7(x - 1)
y = 1.7x - 1.7 + 2.5
y = 1.7x + 0.8
Substitute x = 3 into the above equation:
y = 1.7(3) + 0.8
y = 5.9
Hence, the distance run on day 3 is about 5.9 miles.

1: Write an equation of the line that passes through the points (−2,−7) and (0,−4).
2:Write an equation of a line that passes through the point (2,1) and is perpendicular to the line y=13x+2.
3:You have an initial amount of $55 in a savings account and you deposit an equal amount into your account each week. After 6 weeks the account holds $133. Write an equation that represents the amount y (in dollars) of money in the account after x weeks.
Answer:
1: y=(3x/2)-4 2 :y=(-x/13)+(15/13) 3: y = 13x+55
Step-by-step explanation:
1:
Begin by finding slope
m = (y2-1)/(x2-1)
(-7-(-4)/(-2-0) = 3/2
next use point slope form
y-y1 = m(x-x1) (you can pick any point to use, I will use (0,-4)
y-(-4) = 3/2(x-0)
y+4 = 3x/2
y=(3x/2)-4
2:
The slope of the line y=13x+2 is 13
Take the opposite sign and reciprocal of 13 to get the slope of the line perpendicular; in this case it's -1/13
Next, just like in problem 1, use point slope form.
y-1 = (-1/13)(x-2)
y-1 = (-x/13)+(2/13) (convert 1 to 13/13 for like terms and bring over to the left side)
y=(-x/13)+(15/13)
3:
the intercept will be $55 since it's the initial amount
you know that you deposit some amount every week so set this up as an equation
$133 = m(6)+$55 (the amount deposited every week times 6 +the initial $55 will equal $133)
solving for m gets you $13
so the equation is y = 13x+55
plug in 6 for x to check; 13x6 + 55 = 133
hope this helps

Answer:
[tex]A\,\cap\,C = \{3,5,6\}[/tex]
Step-by-step explanation:
From Set Theory we know that intersection is a binary operation between two sets consisting in labeling the common elements of both sets. If [tex]A=\{1,2,3,4,5,6\}[/tex] and [tex]C =\{3,5,6,7,8,9\}[/tex], then [tex]A\,\cap\,C = \{3,5,6\}[/tex].

Zoey made 9 1/2 cups of trail mix for a camping trip. She wants to divide the trail mix into 3/4-cup servings. Thirteen people are going on the camping trip. Can Zoey make enough 3/4-cup servings so that each person on the trip has one serving?
Answer:
Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.
Step-by-step explanation:
Zoey made 9 1/2 cups of trail mix for a camping trip.
She wants to divide the trail mix into 3/4-cup servings.
Thirteen people are going on the camping trip.
This means :
1 person = 3/4 cup servings
13 people = x
Cross Multiply
13× 3/4
= 39/4
= 9 3/4 cup
So for Zoey to be able to serve 13 people the trail mix in 3/4 cup servings, she need 9 3/4 cups of the trail mix
From the she made 9 1/2 cups of the trail mix.
Hence, Zoey cannot make enough 3/4-cup servings so that each person on the trip has one serving.
Katherine is checking the prices of two different catering companies for her wedding reception. Brenda's Bridal Catering charges $300 for a cake plus $18 per person. Sarah's Complete Catering charges $450 for a cake plus $15 per person. Katherine really likes the cake from Sarah's Complete Catering, so she wants to use that company for her reception. Which inequality can be used to find x, the maximum number of people she can invite to the reception so that the total charge from Sarah's Complete Catering is less than the total charge at Brenda's Bridal Catering?
Answer:
Maximum of 50 persons
Step-by-step explanation:
Straight line equation
let the total prices be y
and the number of persons be x
1. Brenda's Bridal Catering charges
the expression for the charges is
y=mx+c
y=18x+300---------------1
2. Sarah's Complete Catering charges
the expression for the charges is
y=mx+c
y=15x+450---------------2
equating 1 and 2 we can then solve for the number of guest as
18x+300=15x+450
18x-15x=450-300
3x=150
divide both sides by 3
x=150/3
x=50
x<=50
Therefore she can invite a maximum of 50 persons

Suppose y varies directly with x and y =75 when x = 6. What is the value of y when x = 5?
Answer:
62.5
Step-by-step explanation:
y∞x
y=kx( where k is the constant)
75=6k
75÷6 =k
12.5=k
therefore the relationship between k,x and y is y=12.5x
y=12.5×5
y=62.5

Answer:
22 degrees
Step-by-step explanation:
The total degree of a triangle is 180 degrees.
we are given two degrees already; 90 degrees (from the right angle sign) and 68 degrees from the problem. If we create an equation to reflect this we can find the missing angle:
180 = 90 + 68 + x
180 = 158 + x
x = 22
Step-by-step explanation:
<TSU=68
<STU=90

Find the volume of the solid formed By revolving the region bounded By the graphs of y=x^3, y=1, and x=2 about the line x-axis
Answer:
the y axis will be 1 and the x axis will be 8
I know that the y axis will be 1 because y=1 and I know that the x axis will be 8 because 2 to cubed will be 8 because when you multiply 2 by 2 you get 4 and when you multiply 4 by 2 the answer will be 8 so the axis will be (1,8)

prove: sinx tanx + sinx/tanx = 1/cosx
Answer:
Look at step-by-step explanation.
Step-by-step explanation:
First write everything in terms of sin and cos:
(sinx)(sinx/cosx) + (sinx)/(sinx/cosx) = (1/cosx)
Then simplify the expression where you can:
(sin^2)/(cosx) + (cosx) = (1/cosx)
Next find a common denominator and add the two numbers on the left side of the equation:
(sin^2)/(cosx) + (cos^2x)/(cos^2x) = (1/cosx)
((sin2^x)+(cos2^x)/(cosx)) = (1/cos)
Finally, use the identity, sin2^x + cos2^x = 1, to simply to numerator:
(1/cosx) = (1/cosx)
