The equation d=65t models the distance, d, that Malcolm's family travels after t hours. 10 miles per hour 15 miles per hour 30 miles per hour 65 miles per hour
Answers
The question is incomplete. Here is the complete question.
Malcolm and Theo's families are both traveling to the same vacation resort. The equation d = 65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.
How much faster did Malcolm's family travel than Theo's family?
a) 10 miles per hour
b) 15 miles per hour
c) 30 miles per hour
d) 65 miles per hour
Answer: b) 15 miles per hour
Step-by-step explanation: Speed is given by the change in distance per change in time or:
[tex]v=\frac{\Delta x}{\Delta t}[/tex]
For Theo's family, the graph shows the change in miles is constant in hours, so, the speed they are traveling is
[tex]v_{T}=\frac{200-0}{4-0}[/tex]
[tex]v_{T}=\frac{200}{4}[/tex]
[tex]v_{T}=[/tex] 50 mph
For Malcolm's family:
At t = 0: d = 65*0 = 0
At t = 4: d = 65*4
Then, Speed is:
[tex]v_{M}=\frac{65*4-0}{4-0}[/tex]
[tex]v_{M}=\frac{65.4}{4}[/tex]
[tex]v_{M}=[/tex] 65 mph
Theo travels at 50 mph and Malcolm at 65 mph, therefore, Malcolm is 15 miles per hour faster than Theo

Answer:
B. (0,1)Step-by-step explanation:
Use the slope-intercept form to find the slope and y-intercept.
The slope-intercept form is y = m x + b , where m is the slope and b is the y-intercept.
y = m x + b
Find the values of m and b using the form y = m x + b .
m = 1
b = 1
The slope of the line is the value of m , and the y-intercept is the value of b .
Slope: 1
y-intercept: 1
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
Choose 0 to substitute in for x to find the ordered pair.
Replace the variable x with 0 in the expression.
f ( 0 ) = ( 0 ) + 1
Simplify the result.
Add 0 and 1 .
f ( 0 ) = 1 The final answer is 1 . 1
The y value at x = 0 is 1 .
y = 1
Choose 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f ( 1 ) = ( 1 ) + 1
Simplify the result.
Add 1 and 1 .
f ( 1 ) = 2
The final answer is 2 . 2
The y value at x = 1 is 2 .
y = 2
Create a table of the x and y values.
x : 0,1
y: 1 ,2
Graph the line using the slope and the y-intercept, or the points.
Slope: 1
y-intercept: 1
x : 0,1
y : 1 ,2

Answer:
D
Step-by-step explanation:
The hypotenuse squared is equal to the sum of the legs squared in a right triangle.
∴ c² = a² + b² (Pythagorean’s Theorem)
c² = 3.4² + 6.7² (substitute the given values for a & b)
c² = 11.56 + 44.89 (square both right hand terms)

a research lab is to begin experiments with a bacteria that doubles every 4 hours. the lab starts with 200 bacteria. a. how many bacteria will be present at the end of 12th hour? b. how many bacteria will be present at the end of one day? please answer this
Answers
Answer:
A) 1600 bacteria
B) 12800 bacteria
Step-by-step explanation:
We are told that the bacteria doubles every 4 hours.
Now, if the amount of bacteria is X, it means that for 4 hours, it becomes 2X and after 8 hours it becomes 2(2X)
For 12 hours, it becomes; 2 × (2(2X))
This means that for 12 hours, it becomes 2 × (2(2X)) = 8X
A) Since the lab starts with 200 bacteria, after 12 hours, it has;
N_12 = 8 × 200.
N_12 = 1600 bacteria
B) From above, we have seen that after t hours, where t is a multiple of 4, the number of bacteria is;
N_t = [2^(¼t - 1)] × (2X)
Where X is initial amount of bacteria.
Thus, after a day which is 24 hours, we have;
N_24 = 2^(¼(24) - 1) × 2X
N_24 = 2^(5) × 2X
Where X is 200, N_24 = 32 × 2(200) = 12800 bacteria
