Answer:

Step-by-step explanation:

Given

Leg =  10

Leg = 6

hypotenuse = ?

equation

c^2 = a^2 + b^2

a = 10

b = 6

Solution

c^2 = 10^2 + 6^2                  Expand

c^2 = 100 + 36                     Combine

c^2 = 136                              Take the square root of both sides

√c^2 = √136

c = 11.66

answer

hypotenuse = 11.66

Answer: 6.5, 6.25, 6.05, 6.007

Step-by-step explanation:

We need to look at each place value to see which one is the biggest. Since the units place is the same for all the numbers, let's look at the tenths place.

6.5, 6.25, 6.05, 6.007

Since 5 is the biggest number out of all that are underlined, 6.5 is the biggest one, and goes first.

2 is the second biggest number out of all that are underlined, so 6.25 goes second.

However, there are 2 numbers that have 0 in their tenths place, so we need to go one place value further: the hundredths place.

6.05, 6.007

Since 5 is bigger than 0, 6.05 goes third. 6.007 is the only number left, so it goes last.

Hence, the order is 6.5, 6.25, 6.05, 6.007

The intensity at a distance of 14 feet is 18.29 ft

The intensity (I) of a light source is inversely proportional to the square of the distance (d) from the source.

Light intensity refers to the strength or amount of light produced by a specific lamp source

The light intensity is measured in terms of lumens per square foot or lumens per square meter.

Therefore,

I ∝ 1 / d²

Hence,

I = k / d²

where

Therefore,

k = Id²

k = 16 × 16

k = 256

Hence,

I = 256 / 14

I = 18.2857142857

I = 18.29 ft

Therefore, the intensity at a distance of 14 feet is 18.29 ft

Answer:

$55

Step-by-step explanation:

so, we know that each day the store will currently sell $2800 worth of shoes.

we want to know the maximum of the expression (40+3x)(70-3x), expanding we get 2800 - 9x^2 + 90x,

the maximum of this would be x = 5, so the price they should charge is 55

The probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977

Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events

The given parameters are:

Mean = 0.8

Variance = 0.0004

Calculate Standard deviation using

σ = √σ²

This gives

σ = √0.0004

Evaluate

σ = 0.2

Calculate the z-score at x = 0.84 using

z = (x - [tex]\bar x[/tex])/σ = √σ²

This gives

z = (0.84 - 0.8)/0.02

Evaluate

z = 2

The probability is then represented as:

P(x > 0.84) = P(z > 2)

Next, we look up the value of the z table of probabilities

From the z table of probabilities, we have:

P(x > 0.84) = 0.977

Hence, the probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977

The average rate of change for this function for the interval from x = 1 to x = 3 is 3

The average rate of change is calculated as:

m = (f(b)- f(a))/(b - a)

The interval is given as:

x = 1 to x = 3

From the table of values, we have:

f(1) = 7

f(3) = 13

So, we have:

m = (13-7)/(3-1)

Evaluate

m = 3

Hence, the average rate of change for this function for the interval from x = 1 to x = 3 is 3

Answer: -7

Step-by-step explanation:

First, lets use the functions to find the answer to f(-8) and g(4)

f(-8) is the same as asking for the value of y when x is -8

Therefore, f(-8) = -5 (according to the graph)

Using the same rule, g(4) would be the value of y when x = 4 which,

according to the graph, g(4) = 3

Plug these values back into the original equation to get:

[tex]-1*f(-8)-4*g(4)=?\\=-1*-5-4*3\\[/tex]

using the order of operations, we will multiply the values first

Step-by-step explanation:

$13,000 was invested at 6% whereas $7,000 was invested at 10% using simple interest approach

What is simple interest?

Simple interest is determined as the amount invested multiplied by the interest rate and the number of years that investment lasts.

I=PRT

I=interest

P=principal

R=rate of return

T=time

Let X be the amount invested at 6%

I at 6%=6%*X*1

I=0.06X

The amount invested at 10% is 20,000-X

total interest=0.06X+0.10*(20000-X)

total interest=1,480

1480=0.06X+0.10*(20000-X)

1480=0.06X+2000-0.10X

1480-2000=0.06X-0.10X

-520=-0.04X

X=-520/-0.04

X=13,000

13,000 was invested at 6%

amount invested at 10%=20,000-X

amount invested at 10%=20,000-13,000

amount invested at 10%=7,000

Answer:

80

Step-by-step explanation:

1) if the number of hamburgers is 'h', number of cheesburgers is 'c', then

2) the condition 'The number of cheeseburgers sold was three times the number of hamburgers' can be written as c=3h. Also

3) the condition 'combined total of 320' can be written as h+c=320, then

4) it is possible to make up the system of equations:

[tex]\left \{ {{c=3h} \atop {c+h=320}} \right. \ = > \ \left \{ {{c=240} \atop {h=80}} \right.[/tex]

5) finally, number of hamburgers is 80.

hi,

a point is given  ( x; y)

standar line equation is  :  y = ax+b

So  with  (3;5)  and  (8;15)  we have  :  

   3a+b = 5

   8a+b = 15

so :  

8a+b - ( 3a +b) =  15 -5

8a +b -3a -b = 10

8a-3a = 10

5a = 10

   a = 10/5

    a = 2

if a = 2  so  3*2 +b = 5

                     6+b = 5

                       b = 5-6

                       b = -1

so let check :  

8*2 + (-1) = 16 -1 = 15

and  3*2 -1 = 6-1 = 5

coordonnate works for both point, so line  is   y = 2x -1
