Even I had to use a calculator.

a. A model for the difference in feet between car A and car B is d(t) = = 0.35t² - 3t - 1.

b. The difference in feet between car A and car B after 10 seconds is 4 feet

c. To tell which car is in the lead,

Since the distance in feet of car A from the starting line is modeled by the function f(t) = 0.25t² + 22t - 1, where t is the time in seconds since the start of the race.

Also, the distance in feet of car B from the starting line is modeled by the function g(t) = -0.1t² + 25t.

The difference in distance between car A and car B d(t) is the difference between their distance from the starting line.

So, d(t) = f(t) - g(t)

= 0.25t² + 22t - 1 - ( -0.1t² + 25t)

= 0.25t² + 22t - 1 + 0.1t² - 25t

= 0.35t² - 3t - 1

So, a model for the difference in feet between car A and car B is d(t) = = 0.35t² - 3t - 1.

Since the difference in distance in feet between car A and car B  is d(t) = 0.35t² - 3t - 1.

To find the difference in distance after 10 seconds, we substitute t = 10 into d(t).

So, d(t) = 0.35t² - 3t - 1.

d(10) = 0.35(10)² - 3(10) - 1

= 0.35(100) - 30 - 1

= 35 - 31

= 4 feet

So, the difference in feet between car A and car B after 10 seconds is 4 feet

Since the difference in distance in feet between car A and car B  is d(t) = 0.35t² - 3t - 1

= f(t) - g(t)

Since

So, to tell which car is in the lead,

Answer:

$1.20

Step-by-step explanation:

if the donuts normally cost 12 dollars, but they are on on sale for 10% off, then all you have to do is divide 12 by 10.

12 ÷ 10 = 1.2

since we are working with money, we need to add a 0 at the end to make it 1.20, since you need 100 cents to make a dollar.

another way you could write the equation is,

10% × 12 = 1.2

1.2 = 1.20

hence, the sale price for the donuts is $1.20

The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.

Critical value is a cut-off value that is used to mark the start of a region where the test statistic, obtained in hypothesis testing, is unlikely to fall in. In hypothesis testing, the critical value is compared with the obtained test statistic to determine whether the null hypothesis has to be rejected or not.

So, when  we compared the obtained value with the critical value then after that  Reject the null hypothesis if the obtained value is more extreme than the critical value.

and, If the value of the test statistic is less extreme than the critical value, then the null hypothesis cannot be rejected.

Step-by-step explanation:

Answer:

70.42 kilometers.

Step-by-step explanation:

43 minutes/60 minutes (1 hour is 60 minutes) = 0.71 hours.

Now we set up a problem here.

50 kilometers/0.71 hours = x kilometers/1 hour

We multiply out 1 hour and cancel out from both sides.

50/0.71 kilometers = 70.42 kilometers.

Therefore, the train was traveling at 70.42 kilometers per hour.

Numbers without fractions are referred to as "whole numbers," and they are made up of positive integers and zero. It is denoted by the letter "W," and its corresponding set of numbers are 0, 1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12,..

A mathematical procedure called addition symbolizes adding objects t to a larger collection. The plus sign ( + ) is used to denote it.

Some examples of the addition of whole numbers is:

For given relations, relation (1) and relation (3) represent y as a function of x.

And relation (2) does not represent y as a function of x.

In this question, we have been given some relations.

We need to determine which relations represent y as a function of x.

We know that a relation is function when there is unique output for each input.

Consider the first relation.

y = -3.4x

For each value of x there's unique and distinct output. Here x can take any real value.

so, the above relation is a function.

Consider the second relation.

We can observe that, for x = 1 there are two outputs i.e., y = 1 and y = -1.

Similarly for x = 4, there are two outputs y = 2 and y = -2.

this means, the second relation is not a function.

Now, consider the last relation.

From this graph we can see that from x = -∞ to x = ∞, there are unique outputs.

So, above graph represents a function.

Also, by vertical line test, the graph represents a function.

Therefore, for given relations, relation (1) and relation (3) represent y as a function of x.

And relation (2) does not represent y as a function of x.

Answer:

An angle measures 26° more than the measure of its complementary angle.

Step-by-step explanation:

Answer:

The term 27p represents the total cost in dollars of pants

The term 13(p+4) represents the total cost in dollars of shirts

The expression 27p+13(p+4) represents the overall cost in dollars of the shirts and pants Christ buys

Step-by-step explanation:

Disclaimer: if the owner can include the options, I can give a better answer.

We know each pair of pants is $27. Since each pair of pants costs $27, we can say the total cost in dollars of pants is equal to 27*P. For each pair of pants Chris buys, he buys 4 shirts. P+4 is the total number of shirts Chris will buy. The price of these shirts in dollars is $13. So we can assume the total cost in dollars of shirts will be 13(P+4). The total expression is the total amount in dollars Chris spends.

After multiplying 0, 3 times and following the laws of exponents, the value yielded is 0.

What is the law of exponents?

When multiplying a number by itself constantly, exponents are employed to illustrate this. For the case, 73 can be used to represent 7 x 7 x 7. The exponent, in this case, is" 3," denoting how numerous times the number 7 has been multiplied. Then, the number that's actually being multiplied is 7, which serves as the base.
