Answer: $8 \leq y\leq 0$

Step-by-step explanation:

As you can see, there are two dotted points on this graph. The range is the y-axis, so in other words, the horizontal line where you see " $y$ " at the top. So look for the numbers in which the point hits. So from the left side of the graph, the point (closed circle) is at 8, that's the first value we note. Now on the right side of the graph, we find that the closed circle is at the x-axis, which we don't need to worry about since we are finding the range, not the domain. The domain is the x-axis. Since the point where the line stays is not on any numbers, it is on the origin, so it's on 0. Also, note that when the point is a closed circle, it is $\leq$ or $\geq$ , however, if it is an open circle, it is or $>$ .

In general, the point

Zanzabum

Answer:

we conclude that when we put the ordered pair (0, a), both sides of the function equation becomes the same.

Therefore, the point (0, a) is on the graph of the function f(x) = abˣ

Hence, option (D) is correct.

Step-by-step explanation:

Given the function

f(x) = abˣ

Let us substitute all the points one by one

FOR (b, 0)

y = abˣ

putting x = b, y = 0

0 = abᵇ

FOR (a, b)

y = abˣ

putting x = a, y = b

b = abᵃ

FOR (0, 0)

y = abˣ

putting x = 0, y = 0

0 = ab⁰

0 = a ∵b⁰ = 1

FOR (0, a)

y = abˣ

putting x = 0, y = a

a = ab⁰

a = a ∵b⁰ = 1

TRUE

Thus, we conclude that when we put the ordered pair (0, a), both sides of the function equation becomes the same.

Therefore, the point (0, a) is on the graph of the function f(x) = abˣ

Hence, option (D) is correct.

Steve can complete the 100m dash in 10 seconds while Paul can run it in 12 seconds. How does Steve's time compare to Paul's?

Lana71 [14]

Let

x---------> Steve's time

y--------> Paul's time

we know that

$x=10\ s\\y=12\ s$

$x < y$ ------> Steve is faster than Paul

Divide x by y

$\frac{10}{12}=\frac{5}{6}$

therefore

<u>the answer is the option</u>

A. Steve is 5⁄6 as fast as Paul

Find the m < A ? A.80 B.145 C.105 D.70

Rainbow [258]

Answer:

D

Step-by-step explanation:

∠ A is the angle opposite side a

the sum of the 3 angles in the triangle = 180° , that is

∠ A + 75° + 35° = 180°

∠ A + 110° = 180° ( subtract 110° from both sides )

∠ A = 70°

A professor wants to estimate how many hours per week students study. A simple random sample of 78 students had a mean of 15.0 h

OleMash [197]

Answer:

interval=(15.085,14.9515)

Step-by-step explanation:

Table:

CI Z

85% 1.440

90% 1.645

95% 1.960

In order to find the interval/estimate of hours per week students study we consider the formula given below:

Interval=X± $\frac{Z*S}{\sqrt{n} }$

where:

X is the mean hours

Z is the value from Z distribution table of Confidence Interval

n is the sample size of students

S is the standard deviation

X=15, Z=1.645, S=2.3hours, n=78

Interval=15± $1.645*2.3/\sqrt{78}$

Interval=15±0.0485

interval=(15.085,14.9515)
