y=10(3.16)^x

Please show the work and I will give u the brainliest:))

Answers

Answer:

[tex]y=10(3.16)^x[/tex]

Step-by-step explanation:

Given equation is,

log(y) = 0.5x + 1

We can rewrite this equation as,

[tex]\text{log}_{10}(y)=0.5x+1[/tex]

y = [tex]10^{(0.5x+1)}[/tex]

[If [tex]\text{log}_a(b)=c[/tex], then [tex]b = a^{c}[/tex]]

y = [tex]10(10)^{0.5x}[/tex]

y = [tex]10[(10)^{0.5}]^x[/tex]

y = [tex]10(3.16)^x[/tex] [Since, [tex]10^{0.5}=3.16[/tex]]

Therefore, [tex]y=10(3.16)^x[/tex] will be the answer.

80 divided by (6 + (3 - 5) X 2)

Answers

Answer:

40

Step-by-step explanation:

remember PEMDAS

our equation looks like tihs: [tex]\frac{80}{(6+(3-5)*2)}[/tex]

1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.

so now our equation looks liek this [tex]\frac{80}{(6-2 *2)}[/tex]

now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this: [tex]\frac{80}{(6-4)}[/tex]

6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.

How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job? (Vou should have 9 answers in question 2​

Answers

Answer: a. c = 30 + 45h

b. $322.50

Step-by-step explanation:

A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours.

This will be calculated as:

c = 30 + 45h

B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job?

Using the expression,

c = 30 + 45h

c = 30 + 45(6 1/2)

c = 30 + 292 1/2

c = 322.50

Therefore, Juan will pay $322.50

HELP DUE SOON!!!Elise says, "If you subtract 14 from my number and multiply the difference by - 4, the result is

Elise's number is

Answers

Answer:

39

Step-by-step explanation:

If you subtract 14 from my number and multiply the difference by -4, you should get -100.

You need to setup the equation that is being given to you.

Subtract 14 from my number.

x - 14

Multiply the difference by -4

(x-14) * -4

You should get -100.

(x-14) * -4 = -100

Solve for x

(Elise's number is X, the missing number).

[tex]-4(x-14) = -100\\-4x+56 = -100\\-4x=-156\\x=39[/tex]

17.7 meters
B.
25 meters
С
5 meters
D
313 meters

Answers

Answer:

The ladder needs to be placed at 5 m from the wall.

Step-by-step explanation:

Pythagoras's Theorem

Being a and b the legs of a right triangle and c its hypotenuse, then

[tex]c^2=a^2+b^2[/tex]

The image shows a ladder of length c=13 m as the hypotenuse of the right triangle formed by the height, the ladder, and the ground.

We are given the height up the wall as a=12 m.

We calculate the distance b solving it from the equation above:

[tex]b^2=c^2-a^2[/tex]

Substituting:

[tex]b^2=13^2-12^2[/tex]

Operating:

[tex]b^2=169-144[/tex]

[tex]b^2=25[/tex]

Taking the square root:

[tex]b=\sqrt{25}[/tex]

b = 5 m

The ladder needs to be placed at 5 m from the wall.

What equation is equivalent to 2+3(2x+4)=13

Answers

Answer:

14+6x=13, or further 1+6x=0

Step-by-step explanation:

2+3(2x+4)=13,

Distribute the 3 into the parenthesis:

2+6x+12=13

Now combine like terms: 14+6x=13.

You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches. He also uses 333.06 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

The amount of fabric was used on :

a) headband for each player = 15.88 inches of fabric

b) wristband for each player = 8.54 inches of fabric

Step-by-step explanation:

From the above question, we were told:

For headbands

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches.

Total number of persons = 39 players + 3 coaches = 42 persons

42 persons = 666.96 inches

1 person = x

Cross Y

42x = 666.96 inches

x = 666.96 inches/42

x = 15.88 inches

For wristbands

He also uses 333.06 inches of fabric on wristbands for just the players.

We have 39 players

Hence:

39 players = 333.06 inches

1 players = x

Cross Multiply

39x = 1 × 333.06 inches

x = 333.06 inches/3

x = 8.54 inches

The amount of fabric was used on :

a) headband for each player = 15.88 inches of fabric

b) wristband for each player = 8.54 inches of fabric
