Answer:
The equation t = d + 16 represents the scenario
Step-by-step explanation:
The independent variable, the input, is the variable d, representing distance. The distance traveled depends on the amount of time Marlene rides her bike. The initial value of the scenario is 16 miles per hour. so The equation t = d + 16 represents the scenario

Which numbers complete the blanks when solving the equation cos(x+2pi)= -(square root of 2/2) over the interval [0, 2pi]?
Answer:
1, 0
Step-by-step explanation:
Let [tex]\cos (x+2\pi) = -\frac{\sqrt{2}}{2}[/tex]. From Trigonometry we remember the following identity:
[tex]\cos (a+b) = \cos a \cdot \cos b - \sin a \cdot \sin b[/tex] (Eq. 1)
Where [tex]a[/tex] and [tex]b[/tex] are angles measured in radians.
Then, we proceed to expand the given expression:
[tex]\cos x \cdot \cos 2\pi - \sin x \cdot \sin 2\pi = -\frac{\sqrt{2}}{2}[/tex]
[tex]\cos x \cdot 1 - \sin x \cdot 0 = -\frac{\sqrt{2}}{2}[/tex]
[tex]\cos x = -\frac{\sqrt{2}}{2}[/tex]
Therefore, correct answer is "1, 0".

Seventy-five students randomly selected from the junior class at a high school were given a survey asking how much time they spent studying for a math test. Assume the population is normally distributed. The population is The sample is.
Population is like superset of sample. The population and sample for this case are:
Population is: The junior class' students of the considered high schoolSample is: Those 75 randomly selected students.What is the difference between population and sample?The difference between population and sample is that sample is taken from the population.
Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population.
For this case, we have:
75 students were randomly selected from the junior class at a high school.
Since 75 students were selected from junior class, thus:
the population was: The junior class' students of that high schooland, the sample was: Those 75 randomly selected students.Learn more about sampling here:

If $1 in U. S. Dollars is equivalent to 0. 1277 chinese yuan , convert $ 11,000to yuan
Answer:
$11,000 = 1404.7yuan
Step-by-step explanation:
$1 = 0.1277 yuan (multiply both sides by 11,000)
$1 × 11,000 = 0.1277 × 11,000 yuan
$11,000 = 1404.7 yuan

Summer got 12 multiple choice and four constructed response questions correct. Summer scored eight points more than Kerry who got 10 multiple-choice and three constructed response questions correct. Enter an equation that shows how much each multiple-choice question (m) and each constructed response question (c) is worth.
Answer: 2m + c =4
Step-by-step explanation:
Let m = Number of multiple-choice questions
c = Number of constructed response questions
For Summer,
Total marks = 12m + 4c
For kerry,
Total marks = 10m+3c
Summer scored eight points more than Kerry implies
12m + 4c = 4+(10m+3c)
⇒ 12m + 4c = 4+ 10m+3c
⇒ 12m + 4c - 10m-3c =4
⇒ 2m + c =4
Hence, required equation that shows how much each multiple-choice question (m) and each constructed response question (c) is worth. :
2m + c =4
Hello people ~
factorise: x^2 + 15x + 26
Answer:
(x +13)(x + 2)
Step-by-step explanation:
Sum = 15
Product = 26
Factors = 2 , 13
When we add the factors , we get 15 ( 13 +2 = 15)
When we multiply 2 and 13, we get 26 (13*2 = 26)
x² + 15x + 26 = x² + 13x +2x + 26
=x(x + 13) + 2(x + 13)
= (x +13)(x + 2)
So far as to attempt this question we can do either it by factorisation method by creating factors OR by splitting middle term method.
[tex]\mapsto\sf{ {x}^{2} + 15x + 26}[/tex]
Splitting middle term 15x in terms of 13x and 2x gives their sum to 15x and their product is equal to 26.
[tex]\mapsto\sf{ {x}^{2} + 13x + 2x + 26 = 0}[/tex]
[tex]\mapsto\sf{x(x + 13) + 2(x + 13)} = 0[/tex]
[tex]\mapsto\sf{(x + 2)(x + 13) = 0}[/tex]
CASE 1:
[tex]\mapsto\sf{x + 2 = 0}[/tex]
CASE 2:
[tex]\mapsto\sf{x + 13 = 0}[/tex]
Thus,
[tex]\sf{ \therefore \: ( {x}^{2} + 15x + 26) = (x + 2)(x + 13)}[/tex]
