For the linear model, y = -67.9x +679, the distance, in miles y, is a function of time, x, in hours. Use the model to calculate the total distance, in miles, at x = 2 hours.
Answer:
543.2 miles
Step-by-step explanation:
Input the given value of x into the equation and solve for y:
y = -67.9x + 679
y = -67.9(2) + 679
y = -135.8 + 679
y = 543.2
The total distance in miles after 2 hours is 543.2 miles.
Helen has $100 to spend on new school clothes. She has purchased three shirts that cost the same for a total of $36.75. If she buys two more shirts at the same price, how much money will Helen have left to spend?
Answer:
$-83.75
Step-by-step explanation:
She won't have any more money to spend
Multiply $36.75 by 5
That would be $183.75
Subtract 183.75 from 100
-83.75
So Helen wouldn't have anything left to spend.
She would actually be in debt because she used more than $100

Find the slope given for (-2,-5) and (3,-2)
Answer:
The slope is 3/5
Answer:
3/5
Step-by-step explanation:
The slope is given by
m = ( y2-y1)/(x2-x1)
= ( -2 - -5) / ( 3 - -2)
= ( -2+5)/( 3 +2)
= 3/5

Brent and Sarah agree to share a bag of skittles in the ratio 3 to 2. If Sarah gets 52 skittles, how many skittles are in the bag
Answer:
130 skittles
Step-by-step explanation:
Since Sarah is the 2 side of the ratio, i divided her side of it by 2 so i could multiply by 5 to get the full bag. 3:2 = 78:52 skittles
Which Division Property is shown below?
0
------ = 0
14-8
Answer:
When a number 'x' is divided by another number 'y', the number 'x' is divided into 'y' number of equal parts.
If 'y' divides 'x' without any remainder, then 'x' is evenly divisible by 'y'.
Step-by-step explanation:
(i) When 21 is divided by 3, 21 is divided into three equal parts and the value of each part is 7.
(ii) When we divide 35 by 5, we get
7 + 7 + 7 + 7 + 7
(iii) When 35 is divided by 5, 35 is divided into 5 equal parts and the value of each part is 7. And also, there is nothing left over in 35.
So, 35 is evenly divisible by 5.
(iv) When 35 is divided by 4, we get
8 + 8 + 8 + 8 + 3
There is remainder 5, when 35 is divided by 3.
So, 35 is not evenly divisible by 4.
Property 2 :
When a number is divided by another number, the division algorithm is, the sum of product of quotient & divisor and the remainder is equal to dividend.
What is the equation of the line that has a slope of -4 and passes through ( 9, -5)
Answer:
y = -4x + 31
Step-by-step explanation:
y = mx + b
y = -4x + b
-5 = -4(9) + b
-5 = -36 + b
b = 31
Consider the following.
cos(x) = x3
A) Prove that the equation has at least one real root.
The equation cos(x) = x3 is equivalent to the equation f(x) = cos(x) − x3 = 0. f(x) is continuous on the interval (0, 1) there is a number c in (0, 1) such that f(c) = 0 by the Intermediate Value Theorem. Thus, there is a root of the equation cos(x) = x3, in the interval (0, 1).
B) Use your calculator to find an interval of length 0.01 that contains a root.
Answer:
Step-by-step explanation:
Given that:
cos(x) = x³
f(x) = cos (x) - x³
f(x) is continuous on the interval (0, 1)
when;
f(0) = cos (0) - (0)
f(0) = 1 - 0
f(0) = 1 > 0
f(1) = cos (1) - 1³
f(1) = 0.5403 - 1
f(1) = -0.4597
f(1) = - 0.46
f(1) = - 0.46 < 0
Since, 1 > 0 > -0.46, thus there is a number ''c" in (0,1)
such that f(c) = 0
By applying the Intermediate Value Theorem, there is a root of the equation in the interval (0,1)
b) Given that:
The interval length = 0.01; this implies that it is 0.005 length from its root.
f(0.865) = 0.0014
f(0.87) = - 0.013
The solution to the interval lies between 0.865 , 0.87 by using a calculator at length 0.01.
x - y = 11 and 2x + y = 19 by elimination
Answer:
(14,3)
Step-by-step explanation:
2x + y = 19
x - y = 11
-2(x - y) = -2(11)
-2x + 2y = -22
-2x + 2y = -22 + 2x + y = 19
3y = -3
y = 3
-------------------------------------------------
x - y = 11
x - 3 = 11
x = 11 + 3
x = 14

-8 - x = x - 4x
how does x equal to 4 and how do u do this
Answer:
x=4
Step-by-step explanation:
-x=-3x+8
-x+3x=-3x+8+3x
2x=8
2x/2 = 8/2
x = 4
when f(×)=-4(1/2)^-x, what is f(2)
Answer:
16
Step-by-step explanation:
Given expression:
f(x) = 4 [tex](\frac{1}{2} )^{-x}[/tex]
Now we are to find f(2);
To find f(2) we are to substitute 2 for any place where we find x;
f(2) = 4 [tex](\frac{1}{2} )^{-2}[/tex]
f(2) = 4 x [tex]\frac{1}{(\frac{1}{2})^{2} }[/tex]
f(2) = 4 x [tex]\frac{1}{\frac{1}{4} }[/tex]
f(2) = 4 x 4 = 16
Michelle jumps from a plane at an altitude of 1000 m. After 10 seconds her parachute opens. The graph shows the relationship between the distance traveled and time. How long does it take for her to be half way between the plane and the ground? (1 point)
Continuous graph with the y axis labeled Distance (m) and the x axis labeled Time, min. The function consists of 3 lines, the first is almost vertical with a positive slope connecting the points 0,0, to approximately 1 of 6, 250. From that point the second line connects to the first and passes through the points 1,500, 2,800 and 2 1 over 3, 1000. From that point the function is horizontal.
a
40 s
b
1 min
c
1 min 20 s
d
1 min 40 s
Answer:
B
Step-by-step explanation:
If you look at the graph/chart, it starts at 1,000, so half of that is 500, so you go down to 500, and go straight down to see the number of time under it (In this case, is 1 minute) so you know it is one minute
Graph the equation y = x2 + 6x + 5 on the accompanying set of axes. You must
plot 5 points including the roots and the vertex.
Answer:
Please check the graph below.
Step-by-step explanation:
Given the function
[tex]y\:=\:x^2\:+\:6x\:+\:5[/tex]
Axis interception points of the function
x-axis interception points can be computed by setting y=0
[tex]x^2+6x+5=0[/tex]
[tex]\left(x+1\right)\left(x+5\right)=0[/tex]
Using the zero factor principle
if [tex]\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
[tex]x+1=0\quad \mathrm{or}\quad \:x+5=0[/tex]
[tex]x=-1,\:x=-5[/tex]
Hence,
x-axis interception points are: (-1, 0), (-5, 0)
y-axis interception points can be computed by setting x=0
[tex]x^2+6x+5=0[/tex]
[tex]y\:=\:\left(0\right)^2\:+\:6\left(0\right)\:+\:5[/tex]
[tex]y=0+0+5[/tex]
[tex]y=5[/tex]
Hence,
y-axis interception points are: (0, 5)
From the graph, it is clear that at (-3, -4) the parabola changes direction, hence (-3, -4) it the "vertex".
Also at the point x=-2, then y is = -3
So, all the points are labeled and the graph is attached below.

Answer:
see explanation
Step-by-step explanation:
Using the product/ difference identity
sinxsiny = [tex]\frac{1}{2}[/tex] [ cos(x - y) - cos(x + y) ]
Consider the left side
2sin([tex]\frac{\pi }{4}[/tex] + α)sin([tex]\frac{\pi }{4}[/tex] - α )
= cos[[tex]\frac{\pi }{4}[/tex] + α - [tex]\frac{\pi }{4}[/tex] + α ] - cos [[tex]\frac{\pi }{4}[/tex] + α + [tex]\frac{\pi }{4}[/tex] - α ]
= cos2α - cos[tex]\frac{\pi }{2}[/tex]
= cos2α - 0
= cos2α = right side , thus proven

The sum of two complementary angles is 90 degrees.
Angle A + Angle B = 90
Let Angle B = X
5x + 2 + x = 90
Combine like terms:
6x +2 = 90
Subtract 2 from both sides:
6x = 88
Divide both sides by 6:
x = 88/6
x = 14.67
Angle B = 14.67 degrees ( rounded to the nearest hundredth)
