Answer:

Correct choices are A and D.

Step-by-step explanation:

According to the table for the given function [tex]h(x),[/tex] you can write the same table for the inverse function [tex]h^{-1}(x).[/tex] With this aim change [tex]x[/tex] into [tex]h^{-1}(x)[/tex] and [tex]h(x)[/tex] into x:

[tex]\begin{array}{ccccccc}x&2&5&8&11&14&17\\h^{-1}(x)&0&1&2&3&4&5\end{array}[/tex]

Then you can see that points (5,1) and (2,0) are on the graph of the inverse function.

Answer:

total earning is  $64.80

Step-by-step explanation:

Price of one work = $18.00

Payment  by owner = 1/4 of $18.00

                                 = 18/4

                                  = $4.50

Earning by tip =  20% of $18.00 =  20/100 x18 = 3.60

Total earning from one work   =   $4.50+$3.60

                                                = $ 8.10

Earning from 8 tips =  8x8.10

                                = $64.80

Answer:

The correct answer option is: [tex]S_9=\frac{9}{2} (2+26)[/tex]

Step-by-step explanation:

We know that,

the sum of the first [tex]n[/tex] terms of an Arithmetic Sequence is given by:

[tex]S_9=\frac{n(a_1+a_n)}{2}[/tex]

where [tex]n[/tex] is the number of terms,

[tex]a_1[/tex] is the first term of the sequence; and

[tex]a_n[/tex] is the first term of the sequence.

So for [tex]a_n=3n-1[/tex],

[tex]a_1=3(1)-1=2[/tex]

and

[tex]a_9=3(9)-1=26[/tex]

Putting these values in the formula to get:

[tex]S_9=\frac{9(a_1+a_9)}{2}[/tex]

[tex]S_9=\frac{9(2+26)}{2} \\\\S_9=\frac{9}{2} (2+26)[/tex]

First five terms:

[tex]a_1=3(1)-1=2[/tex]

[tex]S_1=\frac{1(2+2)}{2}[/tex]=2

[tex]a_2=3(2)-1=5[/tex]

[tex]S_2=\frac{2(2+5)}{2}[/tex]=7

[tex]a_3=3(3)-1=8[/tex]

[tex]S_2=\frac{3(2+8)}{2}[/tex]=15

[tex]a_4=3(4)-1=11[/tex]

[tex]S_4=\frac{4(2+11)}{2}[/tex]=26

[tex]a_5=3(5)-1=14[/tex]

[tex]S_5=\frac{5(2+14)}{2}[/tex]=40

Answer: the corrrect one is A s9=9/2(2+26)

The height of Cone Mountain, given the trail length and the radius, would be C. 2,520 feet

How to find the height ?

To find the height of Cone Mountain, we can use the properties of a right circular cone. The key relationship we'll use is the Pythagorean theorem :

[tex]l^2 = r^2 + h^2[/tex]

The slant height (l) is the length of the trail, which is 3,150 feet.

The radius (r) is 1,890 feet.

Pythagorean theorem:

[tex](3,150)^2 = (1,890)^2 + h^29,922,500 = 3,572,100 + h^2[/tex]

Make h the subject:

[tex]h^2 = 9,922,500 - 3,572,100\\h^2 = 6,350,400[/tex]

Take the square root of both sides to find h:

h = √(6,350,400)

h = 2,520 feet

Used PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

First Power, next Addition

Answer: A.

Step-by-step explanation:

2, 5, 10, 17, 26

First, check the difference between each term:

2 → 5 = +3

5 → 10 = +5

10 → 17 = +7

17 → 26 = +9

Since the difference (d) is not the same, this is not an arithmetic sequence.

Now, check the second tier {3, 5, 7, 9}

3 → 5 = 2

5 → 7 = 2

7 → 9 = 2

The difference (d) of the second tier is the same, so it is an exponential sequence.

--> the only option that is an exponential sequence is option A.

Answer:

Step-by-step explanation:

Base area= Length* width

Base area= 4* 2

Base area= 8 square units

First question:

By definition of sine and cosine, we have

[tex]\sin30^\circ=\dfrac h{\sqrt5}\implies h=\dfrac{\sqrt5}2[/tex]

[tex]\cos30^\circ=\dfrac g{\sqrt5}\implies g=\dfrac{\sqrt{15}}2[/tex]

Answer: Cancellation method

Step-by-step explanation:

You divide the denominator by  the denominator number to cancel the fraction out.

The Cancellation method is used to simplify a fraction to its lowest form. It is done by finding the Greatest Common Divisor (GCD) of the numerator and the denominator and dividing both by this number.

The method used to reduce a fraction to its lowest form is the Cancellation method. This method involves finding the greatest common divisor (GCD) of the numerator and the denominator of the fraction. Once the GCD is found, divide both the numerator and the denominator by this number. This will reduce the fraction to its simplest or lowest form. For example, if we have the fraction 6/8, the GCD of 6 and 8 is 2. Dividing both 6 and 8 by 2, we retrieve the reduced fraction which is 3/4.

The least common multiple of 7 and 3 is 21, so both the football and volleyball teams will have games on the same day again in 21 days.

The question requires us to determine when the football and volleyball teams will have games on the same day again. Since the football team plays every 7 days and the volleyball team plays every 3 days, we are looking for the least common multiple (LCM) of 7 and 3, which represents the number of days until both teams will have games on the same day again.

To find the LCM of 7 and 3, we can list the multiples of each number until we find a common multiple:

Multiples of 7: 7, 14, 21, 28, ...

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, ...

The first common multiple we encounter is 21. Therefore, both teams will have games on the same day again in 21 days.

Question: if a parabola never touches the x axis, then it doesn't have any real roots or solutions

Answer: True

A real solution only occurs if the graph touches or crosses  the x axis, as the x intercept (or root) is a visual indication of a real number solution. In this case, we have 2 complex solutions for the parabola

Question: What number is equivalent to sqrt(-49) ?

Answer: choice A) 7i

Simplify as follows

sqrt(-49) = sqrt(-1*7^2)

sqrt(-49) = sqrt(-1)*sqrt(7^2)

sqrt(-49) = i*7

sqrt(-49) = 7i

note: be careful not to toss in -7i as one of the answers, because it's not. The square root of a number is exactly one output. For instance, if you take the square root of 25, the result is 5 (not plus or minus 5).

The instantaneous rate of change of the surface area with respect to the radius, r, when r = 3, is 16π

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.

Given that, the surface area of a right circular cylinder of height 2 feet and radius r feet is given by S(r) = 2πrh+2πr².

We need to find, the instantaneous rate of change of the surface area with respect to the radius, r, when r = 3.

Taking the differentiation, of the formula given, S(r) = 2πrh+2πr². w.r.t radius r,

d [S(r)] / dr = 2πh + 4πr

= 2π [h + 2r]

Put h = 2, r = 3

= 16π

Hence, the instantaneous rate of change of the surface area with respect to the radius, r, when r = 3, is 16π

Final answer:

The test statistic for the hypothesis test regarding the proportion of veterinary clinics that do not treat large animals is approximately 5.11, calculated using the formula for the test statistic of a proportion.

Explanation:

The student is asking about calculating a test statistic for a hypothesis test concerning the proportion of veterinary clinics that do not treat large animals such as cows and horses. The proportion as per the American Veterinary Medical Association's belief is 0.5, and the survey conducted has resulted in 88 out of 120 clinics stating they do not treat large animals. To find the test statistic, we can use the formula for the test statistic of a proportion:

Test Statistic (Z) = (p - P₀) / √(P₀(1 - P₀)/n), where p is the sample proportion, P₀ is the null hypothesis proportion, and n is the sample size.

In this case:

p = 88/120

P₀ = 0.5 (as per the hypothesis)

n = 120

Substituting these values, we get:

Z = (88/120 - 0.5) / √(0.5 * (1 - 0.5) / 120) = (0.7333 - 0.5) / √(0.25 / 120) = 0.2333 / √(0.0020833) = 0.2333 / 0.04564 ≈ 5.11

Therefore, the test statistic is approximately 5.11, when rounded to two decimal places.
