Answer:
BX
Step-by-step explanation:
D = RT is an extremely important and useful formula. This formula relates distance, to rate, and time.
In this question, we are asked to find the DISTANCE travelled in the biking portion of the triathlon. Looking back to the formula, we see that the distance is equal to the rate multiplied by the time.
The rate biking is also called the average speed, which is represented by an X in this problem.
The time biking is represented by a B in this problem.
Thus, we obtain our final answer, B times X, or simply written as BX.
Determine the inverse of the following.
y =- log(x - 1) + 2
Answer:
[tex]f^{-1}[/tex](x)=[tex]10^{-x+2}[/tex]+1
Step-by-step explanation:
The temperature in Pullman, WA was 37°F in the afternoon. After the sun went down, the temperature dropped 7 degrees. Write an equation to represent the situation. What was the temperature after the sun went down?
Since the temperature dropped 7 degrees, we will subtract 7 degrees from the original temperature given.
Write an equation to represent the situation:
37°F - 7°F = x
What was the temperature after the sun went down:
37°F - 7°F = x
30°F = x
The temperature after the sun went down was 30°F.
PLS ANSWER THISHEHDNDJDJ
9514 1404 393
Answer:
1/12
Step-by-step explanation:
The slope of a ramp (or anything else) is the ratio of its "rise" to its "run."
The rise is the vertical change. Here, that is shown as 3 m.
The run is the horizontal change. Here, that is shown as 36 m.
Then the slope is ...
[tex]\text{slope }=\dfrac{\text{rise}}{\text{run}}=\dfrac{3\text{ m}}{36\text{ m}}=\boxed{\dfrac{1}{12}}[/tex]
__
Additional comment
If this were a line on a graph, the slope would be calculated the same way. When the rise is positive to the right, the slope is positive. On a graph, if the rise is negative as you go to the right, the slope is negative.

Using xn+1 = 1 -(3/x^2)
with x0 = -2.5
Find the values of X1, X2 and X3 using iteration
Answer:
The values of [tex]x_{1}[/tex], [tex]x_{2}[/tex] and [tex]x_{3}[/tex] are 0.52, -10.094 and 0.971.
Step-by-step explanation:
Let [tex]x_{n+1} = 1-\frac{3}{x_{n}^{2}}[/tex] be the recurrence formula and [tex]x_{o} = -2.5[/tex]. The first values of this recurrence are, respectively:
[tex]x_{1}[/tex]:
[tex]x_{1} = 1 - \frac{3}{x_{o}^{2}}[/tex]
[tex]x_{1} = 1-\frac{3}{(-2.5)^{2}}[/tex]
[tex]x_{1} = 0.52[/tex]
[tex]x_{2}[/tex]:
[tex]x_{2} = 1-\frac{3}{x_{1}^{2}}[/tex]
[tex]x_{2} = 1-\frac{3}{0.52^{2}}[/tex]
[tex]x_{2} = -10.094[/tex]
[tex]x_{3}[/tex]:
[tex]x_{3} = 1-\frac{3}{x_{2}^{2}}[/tex]
[tex]x_{3} = 1 - \frac{3}{(-10.094)^{2}}[/tex]
[tex]x_{3} = 0.971[/tex]
The values of [tex]x_{1}[/tex], [tex]x_{2}[/tex] and [tex]x_{3}[/tex] are 0.52, -10.094 and 0.971.
Answer:
= 0.52, -10.094 and 0.9705561461

The measure of an angle is 32.9°. What is the measure of its complementary angle?
Answer: 57.1
Step-by-step explanation: To be complementary the angles have to add up to make a sum of 90.
90 - 32.9 = 57.1
The angles are 32.9 and 57.1.
[tex]9 - 3 \div \frac{1}{3} + 1[/tex]
i need help with math problem
Given:
The expression is
[tex]9-3\div \dfrac{1}{3}+1[/tex]
To find:
The value of given expression.
Solution:
We have,
[tex]9-3\div \dfrac{1}{3}+1[/tex]
BODMAS : Bracket, Order, Division, Multiplication, Addition, and Subtraction.
Using BODMAS, first we need to perform division in the given expression.
[tex]=9-(3\div \dfrac{1}{3})+1[/tex]
[tex]=9-(3\times 3)+1[/tex]
[tex]=9-9+1[/tex]
Now, apply addition.
[tex]=(9+1)-9[/tex]
[tex]=10-9[/tex]
Now, apply subtraction.
[tex]=1[/tex]
Therefore, the value of given expression is 1.

A real-world situation that is represented in the table is “Rio’s car gets 23 miles per gallon.”.
A real-world situation that is represented in the table is “Rio’s car gets 1 mile per 23 gallons.”.
Answer:
Gallons Miles
2 56
4 a
b 168
10 c
To Find : the missing values a , b , c and constant of proportionality
Solution:
constant of proportionality of x miles per gallon
=> Miles = x * gallons
Gallons = 2
=> Mile s= 2 * x = 56
=> x = 28
Gallons = 4
=> Mile s= 4 * 28 = 112 = a
Gallons = b
=> Mile s= b * 28 = 168
=> b = 7
Gallons = 10
=> Mile s= 10 * 28 = 280 = c
Gallons Miles
2 56
4 a =112
b=7 168
10 c=280
constant of proportionality = 28
a = 112
b = 7
c = 280

18 What is the equation of the line that is perpendicular to y = -x – 10 and contains point (-12, 1)? A y = X - 8 B y = - 15 C y = -x - 8 D y = 3*+ 17
Answer:
The equation of the line that is perpendicular to y = -x – 10 and contains point (-12, 1)
[tex]y=x+13[/tex]
Please note there is something wrong with the values given question. This is correct answer.
Step-by-step explanation:
Slope of line y = -x – 10 is m1=-1
Since slope of perpendicular lines are negative reciprocal of each other
Slope of other line is m2=1
Equation of line contains point (-12, 1) and having slope m2=1 is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-1 = 1(x+12)[/tex]
[tex]y =x+12+1 \\y = x + 13[/tex]
Where is the blue dot on the number line?
++
十
6
0
6
Step-by-step explanation:
Each space between 2 lines represent 6 units. (from -6 to 0 is 6 units, from 0 to 6 is 6 units)
Since the blue dot is 3 spaces to the right of 0, it is 3 * 6 units = 18.
The value of the blue dot is 18.

what is the domain and range of this and it is a function?
Answer:
Domain: [-8,inf)
Range: [-3,5]
Function: Yes
Step-by-step explanation:
First, this relation is a function because x's never repeat. The domain is every x-value that the graph covers, on this graph x's start at -8, which is included, and then continue forever. So the domain should be written as [-8,inf) because it is from least to greatest and the bracket shows -8 is included. The range is the y-values the graph covers. On this, the highest y is 5, and then the graph flattens at -3, both points are included. So the range must be [-3,5].
