Help! I'm confused!​

Answer:

2. ) {25}^{2x} - 1 = {125}^{3x} + 4

=> {25}^{2x} = {125}^{3x} + 4 +1

=> {(5)^(2)}^{2x} = {(5)^(3)}^{3x} + {5}^{1}

=> {5}^{4x} = {5}^{9x} + {5}^{1}

=> 4x = 9x + 1

=> 4x - 9x = 1

=> - 5x = 1

=> x = 1/-5

Answer:

the third one

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

Asuming the equation is 8x-4=60°,

Simplifying

8x + -4 = 60

Reorder the terms:

-4 + 8x = 60

Solving

-4 + 8x = 60

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 8x = 60 + 4

Combine like terms: -4 + 4 = 0

0 + 8x = 60 + 4

8x = 60 + 4

Combine like terms: 60 + 4 = 64

8x = 64

Divide each side by '8'.

x = 8

Simplifying

x = 8

Answer:

18 number of daisies and 18 number of roses

Step-by-step explanation:

We are told Darrel has 36 daisies and 54 roses.

And that He wants to put an equal number of daisies and roses into vases.

To get the equal number, it means we have to find the greatest common factor of 36 and 54.

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

Factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54

From the factors of both 36 and 54, the greatest common factor to both of them is 18.

Thus, the GREATEST number of daisies and roses Darrel can put in each vase is 18 each

Answer:

18

Complete Question

Recall the hurricane relief fund context from the previous investigation. Bob set up a hurricane relief donation fund and started it off by donating $ 35 . Instead of tripling in value each day, suppose it doubled in value each day

Complete the following table showing the account values at the end of each day.

Number of days since the initial investment, n Amount (in dollars) in the relief account, A

0 1 2 3 4

Answer:

Number of days(n) = Amount (in dollars) in the relief account(A)

0 = $35

1 = $70

2 = $140

3 = $280

4 = $560

Step-by-step explanation:

The formula for doubling time

P(t) = Po(2)^t/k

Where P = Amount after time t

Po = Initial Amount

t = number of days

k = Frequency at which it doubles

For 0 days

t = 0, k = 1, P(o) = $35

P(t) = Po(2)^t/k

P(0) = $35(2)^0/1

= $35(2)⁰

= $35 × 1

= $35

For 1 day

t = 1, k = 1 , P(0) = $35

P(t) = Po(2)^t/k

P(0) = $35(2)^1/1

= $35(2)¹

= $35 × 2

= $70

For 2 days

P(t) = Po(2)^t/k

t = 2, k = 1, P(0) = $35

P(0) = $35(2)^2/1

= $35(2)²

= $35 × 4

= $140

For 3 days

P(t) = Po(2)^t/k

t = 3, k = 1

P(0) = $35(2)^3/1

= $35(2)³

= $35 × 8

= $280

For 4 days

P(t) = Po(2)^t/k

t = 3, k = 1, P(0) = $35

P(0) = $35(2)^5/1

= $35(2)⁴

= $35 × 16

= $560

Answer:

-7 = h

Step-by-step explanation:

15.3 + 1h = 1.3 - 1h

        +1h          +1h

15.3 + 2h = 1.3

Remember what you do to one side you MUST do to the other.

 15.3 + 2h = 1.3

-15.3           -15.3

2h = -14

Now to isolate the variable you divide both sides by 2 to get, h = -7

Hope that helps and have a great day!

Hey there!☺

[tex]Answer:\boxed{h=-7}[/tex]

[tex]Explanation:[/tex]

[tex]15.3+1h=1.3-1h[/tex]

In our first step, we will simplify both sides in the equation:

[tex]15.3+h=1.3+-h\\h+15.3=-h+1.3[/tex]

Now add h to both sides:

[tex]h+15.3+h=-h+1.3+h\\2h+15.3=1.3[/tex]

In step 3, divide both sides by 2:

[tex]\frac{2h}{2}=\frac{-14}{2}[/tex]

Simplify -14/2:

[tex]\frac{-14}{2}=-7\\ h=-7[/tex]

h=-7 is your answer.

Hope this helps!☺

Answer: He should not be concerned

Step-by-step explanation:

The variation is still the same and has not changed because the only thing that changed are the units. A unit change does not mean that the diameter has changed, only the method of measuring it has changed.

Absolutely speaking, the diameter is still the same. A standard deviation of  0.1 inches is the same as a standard deviation of 2.54mm so the executive should not be worried.

Answer:

SPEA should have install the new power generator.

Step-by-step explanation:

The information provided is as follows:

Consider the decision tree attached below.

The loss that will be incurred after the generator is installed is, $80,000.

Compute the loss that will be incurred if the generator is not installed as follows:

[tex]E(\text{Loss})=P(HL|P)P(P)\times \$7000000+P(SL|P)P(P)\times \$1000000[/tex]

             [tex]=(0.07\times 0.12\times \$7000000)+(0.93\times 0.12\times \$1000000)\\=58800+111600\\=170400[/tex]

The loss that will be incurred if the generator is not installed is $170,400.

The loss from not installing the generator is more than from installing it.

Thus, SPEA should have install the new power generator.

Answer:

f(1/3) = 9

Step-by-step explanation:

f(x) = 1/x + 2/x

f(1/3) = 1/(1/3) + 2/(1/3)

f(1/3) = 1(3) + 2(3)

f(1/3) = 3 + 6

f(1/3) = 9

Step-by-step explanation:

youre subtracting a negative, which makes it positive. anytime you subtract a negative, its just addition :)

Answer:

2

Step-by-step explanation:

Ok, so it's you are subtracting a negative three from negative one. Since you are subtracting a negative it basically cancels it the negative out and makes it a positive number. So -3 would be 3. It would look like -1 +3, and that's how the answer is 2. Hopes this helps! :D

Answer:

Step-by-step explanation:

given <abd = 48 and <dbc = 78, hence the addition rule is true<abc = <abd + < dbc

Substituting the given values inti the formula;

< abc = 48+78

<  abc = 126°

The measure of angle abc is therefore 126°

Answer:

The answer is H.

Step-by-step explanation:

By adding the two longer sides, you get 6x+4. if you combine the like terms of the shorter sides and the longer sides, you get the equation 6x+4+2x. 6x+4+2x= 8x+4.

Step-by-step explanation:

Hey there!

Here;

A chord of a circle AB is given with measure of 24 cm.

Let O be the centre of a circle and OP is perpendicular to AB.

Now, draw an imaginary line from O to B. [To make a radius].

Now;

[tex]bp = \frac{1}{2} \times ab[/tex]

[tex]bp = \frac{1}{2 } \times 24[/tex]

Therefore BP = 12.

Again;

You can clearly see that POB is a Right angled triangle.

Now,

Using Pythagoras relation we get;

[tex] {ob} = \sqrt{ {po}^{2} + {bp}^{2} } [/tex]

[tex]ob = \sqrt{ {8}^{2} + {12}^{2} } [/tex]

[tex]ob = \sqrt{64 + 144} [/tex]

[tex]ob = \sqrt{208} [/tex]

Therefore OB = 14.42.

As OB is a radius, the value of radius is 14.42.

Hope it helps...
