Answer:

$20

Step-by-step explanation:

20% is equal to 20/100 therefore, if 5 x 20 is 100, you would multiply 5 x 4 and get 20,

the reason you don't subtract the $4 is because it says "was" so the answer is $20

Answer:

80

Step-by-step explanation:

the combined angles of any triangle equal 180 degrees. take the known angles ( 50 and 50) and subtract their sum from 180. 180-100=80

Answer:

D. g(x) = 2-x^2

Step-by-step explanation:

g(x) seems to be a vertical translation of f(x).

f(x) = 5-x^2

g(x) = 5-x^2-3 (subtract 3 as a translation down 3 units)

g(x) = 2-x^2

The sine function is:

[tex]y(x)=\frac{2}{3}sin[3\pi (x-\frac{2\pi}{3})]-2[/tex]

Step-by-step explanation:

We need to recall that a sine function can write as:

[tex]y(x)=Asin[B(x+C)]+D[/tex]

Where:

So we just need to use the listed attributes

Therefore, the sine function is:

Answer:

r=-10 Hope this helps! If I could have brainliest I'm trying to level to level up.

Step-by-step explanation:

Let's solve your equation step-by-step.

3+5r=−47

Step 1: Simplify both sides of the equation.

5r+3=−47

Step 2: Subtract 3 from both sides.

5r+3−3=−47−3

5r=−50

Step 3: Divide both sides by 5.

5r/5=-50/5

r=−10

Answer:

r=−10

Answer:

$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Normally distributed with mean $480 and standard deviation $20.

This means that [tex]\mu = 480, \sigma = 20[/tex]

How much should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05?

This is the 100 - 5 = 95th percentile, which is X when Z has a pvalue of 0.95, so X when Z = 1.645.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.645 = \frac{X - 480}{20}[/tex]

[tex]X - 480 = 1.645*20[/tex]

[tex]X = 512.9[/tex]

$512.90 should be budgeted for weekly repairs and maintenance so that the probability the budgeted amount will be exceeded in a given week is only 0.05

Answer:

467.58

Step-by-step explanation:

Grows 0.4% --> r = .004

Grows every 10 years: exponent of t/10

where t is in years

Write a function:

f(t) = 450(1+0.004)^t/10

96 years means no time conversion is needed due to years being the only unit in the problem

T = 96

f(96) = 450(1+0.004)^96/10

= 467.580247756

≈467.58

youre welcome y'all

Answer:

hi i dont understand this

Step-by-step explanation:

sorry

The function will be

[tex]f(x) = 9 - x + \sqrt[2]{ {x}^{2} + 9} [/tex]

and minimum value required will be

[tex]9 + \sqrt[3]{3} [/tex]

The steps are as follow:

[tex]f(x) = (9 - x) + \sqrt[2]{ (x^2 + 3^2) } \\ =(9 - x) + \sqrt[2]{ (x^2 +9)} \\ f(x) = \frac{2x}{ \sqrt{ {x}^{2} + 9} } - 1 \\ f(x) = 0 \\ \frac{2x}{ \sqrt{ {x}^{2} + 9} } - 1 = 0 \\ \frac{2x}{ \sqrt{ {x}^{2} + 9}} = 1 \\ 2x = \sqrt{ {x}^{2} + 9} \\ 4{x}^{2} = { x}^{2} + 9 \\ 3 {x}^{2} = 9 \\ {x} = \sqrt{3} [/tex]

so putting value of in f(x) we will get

[tex]f( \sqrt{3} ) = 9 - \sqrt{3} + \sqrt[2]{ { (\sqrt{3} )}^{2} + 9} \\ = 9 + 2 \sqrt{3} [/tex]

So The function will be

[tex]f(x) = 9 + \sqrt[2]{ {x}^{2} + 9}[/tex]

and minimum value required will be

[tex]9 + \sqrt[3]{3} [/tex]

Step-by-step explanation:

-2(8x-4)<2x+5

-16x+8<2x+5

-16x-2x+8<5

-16x-2x<5-8

-18x<-3

x>1/6, alternate form x>0.16 and x>6^-1

The solution is, C. x>6^-1, is the solution to -2(8x – 4) < 2x + 5.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

the expression is,

-2(8x – 4) < 2x + 5

now, we have to solve the inequality,

we have,

-2(8x-4)<2x+5

-16x+8<2x+5

-16x-2x+8<5

-16x-2x<5-8

-18x<-3

x>1/6,

so, we get,

alternate form x>0.16 and x>6^-1

Hence, The solution is, C. x>6^-1, is the solution to -2(8x – 4) < 2x + 5.
