Find the domain of the function f left parenthesis x right parenthesis equals cube root of 5 x plus 25 end root

Answer:

25x^2 + 30x + 9

Answer:

Step-by-step explanation:

Select the correct answer from each drop-down menu.

We solve using z score formula

z-score is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

The average time taken to complete a test follows normal probability distribution with a mean of 70 minutes and a standard deviation of 25 minutes.

a) The probability of a randomly selected student completing the test in 45 minutes or less is approximately equal to %.

z = 45 - 70/25

b) The probability of a randomly selected student completing the test in 95 minutes is %.

z = 95 - 70/25

Answer:

The missing term is 20

Step-by-step explanation:

Given

[tex]f(x) = \frac{1}{2}x + 10[/tex]

[tex]h(x) = 2x -[/tex] --- inverse of f(x)

Required

Complete h(x)

We have:

[tex]f(x) = \frac{1}{2}x + 10[/tex]

Express f(x) as y

[tex]y = \frac{1}{2}x + 10[/tex]

Swap x and y

[tex]x = \frac{1}{2}y + 10[/tex]

Multiply through by 2

[tex]2x = y + 20[/tex]

Make y the subject

[tex]y = 2x - 20[/tex]

Replace y with the inverse function

[tex]h(x) = 2x - 20[/tex]

Compare

[tex]h(x) = 2x - 20[/tex]

with

[tex]h(x) = 2x -[/tex]

The missing term is 20

Answer:1733.28

square inches I think

Answer:

1733.28 in^2.

Step-by-step explanation:

The radius r = 1/2 the diameter = 1/2 *12 = 6 inches.

SA = 2*3.14*6^2 + 2*3.14*6*40

= 1733.28 in^2.

Answer:

To fine the surface area is to add all the area of the faces

Answer:

To divide by (x+1) in synthetic division, you divide by -1.

-1    1   -7   4   12

         -1    8   -12

—————————-

     1   -8   12   0

This gives us x^2 -8x +12x  which factors to (x-2) (x-6).  We still have the factor of (x+1)  so the zeros will be 2, 6, and -1.

Answer:

42.42 yards

Step-by-step explanation:

Given :-

And we need to find the length of other leg. So since it is a right angled triangle we can use the Pythagoras Theorem which is ,

Pythagoras Theorem :-

Using Pythagoras Theorem :-

[tex]:\implies[/tex] p² + b² = h²

[tex]:\implies[/tex] 15² + p² = 45²

[tex]:\implies[/tex] 225 + p² = 2025

[tex]:\implies[/tex] p²= 1800

[tex]:\implies[/tex] p = 42.42

Hence the measure of other leg is 42.42 yards.

Answer:

2 AND -10

Step-by-step explanation:

Answer:

domain: all real numbers except 2 and -10; x-intercept: 4; y-intercept:  1/5

Step-by-step explanation:

The domain consists of the set of all possible values x can be. In a fraction, the denominator cannot be equal to 0. We can solve for the values x cannot be equal to by factoring and exclude them out of the domain once we’ve found them:

To factor x^2 + 8x - 20, we are looking for two numbers that have a product of -20 and a sum of 8. These two numbers are 10 and -2. So, it can be factored to:

(x + 10)(x -2) not equal 0

So x ≠ 2 and x ≠ -10.

To find the x-intercept, the value of y would be zero. We can substitute y as 0 to get:

0 = (x - 4) / x^2 + 8x - 20

The only way for this fraction to equal 0, is for the numerator to be 0. We get the equation:

x - 4 = 0,

And x = 4

To find the y-intercept, the value of x would be 0. We can substitute x with 0 to get:

y = -4 / -20 = 1/5

These answers align with the second option.

Answer: 20°

Step-by-step explanation:

Let's call angle 1 x and angle 2 y

We know that x is three times greater than y, and that means that we can write it like this:

3y = x         pls let me know if this part is confusing

Then we can write this entire equation:

3y + y = 80       remember, x = 3y

4y = 80

y = 20

Answer:

B. 2s + 100 when s=80 the latest balance of Ahmed’s savings is $260

Step-by-step explanation:

We are given that the savings = $s and current amount  $c.

Now, Ahmed has doubled his savings. This means that the new savings = $2s

Also, he had deposited $100.

So, the current amount of Ahmed is given by c = 2s + 100.

Moreover, if the savings is $80 i.e. s = 80, the current amount is,

c = 2 × 80 + 100

i.e. c = 160 + 100

i.e. c = 260

So, the current amount if savings is $80 is $260.

Hence, the expression for current amount is 2s + 100 and if s = 80, the current amount is $260.

Answer:

-9

Step-by-step explanation:

Given :-

And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.

Sequence :-

[tex]:\implies[/tex] -5 , -14 , -23

Common difference :-

[tex]:\implies[/tex] CD = -14 -(-5) = -14+5=-9

[tex]:\implies[/tex] CD = -23-(-14) = -23+14=-9

Hence the common difference is (-9) .

Answer:

12.0 meters

Step-by-step explanation:

Given data

The first is 8.75 meters long

Let us find 37.5% of  8.75

=37.5/100*8.75

=0.375*8.75

=3.28125

Hence the Second seawall is

=3.28125+8.75

=12.0 meters

Answer:

[tex]P(Z<-2.5) =0.0062097[/tex]

Step-by-step explanation:

From the question we are told that:

Test statistic t =-2.5

Generally the equation for Test for statistics is mathematically given by

 [tex]t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }[/tex]

 [tex]t=-2.5[/tex]

Therefore

P-value from Z table is

For left tailed test

 [tex]P(Z<-2.5) =0.0062097[/tex]

therefore the P-value for the test is

 [tex]P(Z<-2.5) =0.0062097[/tex]

Answer:

42.5 Cubic Yards

Step-by-step explanation:

To find volume of a rectangle you do length*width*height to get the volume, so 17*15*0.5(because 6 inches is half of a foot) you get 127.5, but they're asking for it in yards not feet so you need to divide 127.5 by 3 and that will give you 42.5.

The volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.

The volume of the cuboid is the space occupied by the 3D object cuboid. It is the product of the length, width, and depth of the cuboid.

As it is given that we need to make a rectangular foundation, therefore, the shape of the foundation will be a cuboid with sides 5 feet wide, 17 feet long, and depth of 6 inches.

Now, as we know large amounts of concrete can be purchased by the cubic yard only, therefore, we will convert each of the sides of the rectangular foundation into yards.

[tex]\rm Wide, w = 5\ feet = 5 \times \dfrac{1}{3} = \dfrac{5}{3}\ yards\\\\Length, L = 17 feet = 17 \times \dfrac{1}{3} = \dfrac{17}{3}\ yards\\\\Depth, D = 6\ inches = 0.5\ feet = 0.5 \times \dfrac{1}{3} = \dfrac{0.5}{3}\ yards\\\\[/tex]

Now, we know that the volume of the cuboid is given as the product of its length, width, and depth. therefore,

[tex]\text{Volume of Cuboid} = Length\times Width\times Depth[/tex]

                             [tex]= \dfrac{5}{3} \times \dfrac{17}{3} \times \dfrac{0.5}{3}\\\\= \dfrac{42.5}{27}\\\\=1.574\rm\ yards^3[/tex]

Hence, the volume of the concrete that would be needed in order to make the rectangular foundation for the patio is 1.574 yards³.
