What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?
Answers
Answer:
15.75 milesStep-by-step explanation:
Step one:
given
time= 2.5 hours
speed= 6.3mph
Step two:
Required
Distance
we are given the speed in miles per hour, hence the distance will be in miles
we also know that the expression relating speed, distance and time is given as
speed= distance/time
thus
distance= speed*time
distance= 6.3*2.5
distance= 15.75 miles
By using expression for the speed, distance traveled by me in 2.5 hours will be
Given in the question,
Speed = 6.3 mphTime for travelling = 2.4 hoursExpression for the speed of an object is given by,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Therefore, Distance = Speed × Time
By substituting the values of speed and the time in the expression,
Distance traveled = 6.3 × 2.5
= 15.75 miles
Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.

Uninhibited growth can be modeled by exponential functions other than A(t) =Upper A 0 e Superscript kt. For example, if an initial population Upper P 0 requires n units of time to triple, then the function P(t)equals Upper P 0 (3 )Superscript StartFraction t Over n EndFraction models the size of the population at time t. An insect population grows exponentially. Complete the parts a through d below.
Answers
The question is incomplete. Here is the complete question.
Uninhibited growth can be modeled by exponential functions other than [tex]A(t)=A_{0}e^{kt}[/tex]. for example, if an initial population P₀ requires n units of time to triple, then the function [tex]P(t)=P_{0}(3)^{\frac{t}{n} }[/tex] models the size of the population at time t. An insect population grows exponentially. Complete the parts a through d below.
a) If the population triples in 30 days, and 50 insects are present initially, write an exponential function of the form [tex]P(t)=P_{0}(3)^{\frac{t}{n} }[/tex] that models the population.
b) What will the population be in 47 days?
c) When wil the population reach 750?
d) Express the model from part (a) in the form [tex]A(t)=A_{0}e^{kt}[/tex].
Answer: a) [tex]P(t)=50(3)^{\frac{t}{30} }[/tex]
b) P(t) = 280 insects
c) t = 74 days
d) [tex]A(t)=50e^{0.037t}[/tex]
Step-by-step explanation:
a) n is time necessary to triple the population of insects, i.e., n = 30 and P₀ = 50. So, Exponential equation for growth is
[tex]P(t)=50(3)^{\frac{t}{30} }[/tex]
b) In t = 47 days:
[tex]P(t)=50(3)^{\frac{t}{30} }[/tex]
[tex]P(47)=50(3)^{\frac{47}{30} }[/tex]
[tex]P(47)=50(3)^{1.567}[/tex]
P(47) = 280
In 47 days, population of insects will be 280
c) P(t) = 750
[tex]750=50(3)^{\frac{t}{30} }[/tex]
[tex]\frac{750}{50}=(3)^{\frac{t}{30} }[/tex]
[tex](3)^{\frac{t}{n} }=15[/tex]
Using the property Power Rule of logarithm:
[tex]log(3)^{\frac{t}{30} }=log15[/tex]
[tex]\frac{t}{30}log(3)=log15[/tex]
[tex]t=\frac{log15}{log3} .30[/tex]
t = 74
To reach a population of 750 insects, it will take 74 days
d) To express the population growth into the described form, determine the constant k, using the following:
A(t) = 3A₀ and t = 30
[tex]A(t)=A_{0}e^{kt}[/tex]
[tex]3A_{0}=A_{0}e^{30k}[/tex]
[tex]3=e^{30k}[/tex]
Use Power Rule again:
[tex]ln3=ln(e^{30k})[/tex]
[tex]ln3=30k[/tex]
[tex]k=\frac{ln3}{30}[/tex]
k = 0.037
Equation for exponential growth will be:
[tex]A(t)=50e^{0.037t}[/tex]
If k(x) = 2x² -3.Vx, then k(9) is
Answers
Answer:
159
Step-by-step explanation:
k (9) = (2 * [tex]9^{2}[/tex]) - 3
= (2 * 81) - 3
= 162 - 3
= 159

cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.
Answers
Given :
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.
To Find :
How much would Mrs. Algebra's single order be.
Solution :
Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.
T = $(0.10 + 0.49 + 12.99 + 0.05)
T = $13.63
Therefore, Mrs. Algebra's single order cost is $13.63 .
Hence, this is the required solution.

1What is the simple interest on #25 000 for 3years at 5% per annum?.
#28 750
#3 750
#2 875
#375
Answers
Answer:
3750
Step-by-step explanation:
Simple interest (I) is calculated as
I = [tex]\frac{PRT}{100}[/tex] ( P is the principal, R is rate of interest and T time in years )
Here P = 25000, R = 5 and T = 3 , thus
I = [tex]\frac{25000(5)(3)}{100}[/tex]
= [tex]\frac{375000}{100}[/tex]
= 3750
