f(x)=5(1+0.25)^x,f(4)

Please show step by step of how you got the answer

Answers

Answer 1

Answer:

f(4) = 12.2

Step-by-step explanation:

we are given that x = 4, plug in 4 into the equation

f(4) = 5(1+0.25)^(4)

f(4) = 5(1.25)^(4)

raise 1.25 to the 4th, which is equal to 2.44

f(4) = 5(2.44)

f(4) = 12.2

The triangles shown below must be congruent.
30
30°
5

OA. True
O B. False

Answers

False. You need to graphically turn the triangle and see if it matches. It’s a trick question, the legs don’t match. They switched the position of the 5 on each triangle and the legs are 100% not equal (30-60-90 triangle).

Note: if the question was changed to 45 degree angle (45-45-90) instead of the famous (30-60-90) then they would be congruent because both legs of each triangle would be 5. In other words the 45 degrees tells us the legs are equal on every triangle but the 30-60-90 triangle tells us 100% the legs must be different.

if (a+1/a) =4, find the value of (a cube +1/a cube)​

Answers

Answer:

a=2+√3 or a=2−√3

Step-by-step explanation:

Multiply all terms by a and cancel:

aa+1=4a                         ∴ (Simplify both sides of the equation)

a2+1−4a=4a−4a            ∴ (Subtract 4a from both sides)

a2−4a+1=0

For this equation:  a=1,  b=-4,  c=1

1a2+−4a+1=0

a = −b ±  √b2 − 4ac2a divided by 2a    ⇒(Use quadratic formula with a=1, b=-4, c=1)

−(−4) ± √(−4) 2−4 (1) (1) /2 (1)

Adsilla and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes. Adsila fills 11 boxes every hour. How many boxes does carlos fill every hour?

Answers

Answer:

[tex]Carlos = 16[/tex] per hour

Step-by-step explanation:

Given

[tex]Total = 108\ boxes[/tex]

[tex]Hours = 4[/tex]

[tex]Adsila = 11\ boxes\ per\ hour[/tex]

Required

Determine the unit rate of Carlos

First, we need to calculate the total boxes filled by Adsila.

If Adsila gets 11 in 1 hour.

Then Adsila get 4 * 11 in 4 hours

[tex]4 * 11 = 44\ boxes[/tex]

Next, we calculate number of boxes left.

[tex]Left = 108 - 44[/tex]

[tex]Left = 64[/tex]

This is yhe number of boxes filled by Carlos.

Recall that they worked for 4 hours each.

Hence:

[tex]Carlos = \frac{64}{4}[/tex]

[tex]Carlos = 16[/tex]

f(x)=-2x+3
g(x)=3x+3
find f(1-x) + g(1-x)

Answers

Answer:

-5x + 11

Step-by-step explanation:

All you're doing is substituting.

f(x)=-2x+3

f(1-x) = 2(1-x)+3

= 2 - 2x +3

= -2x + 5

g(x)=3x+3

g(1-x) = 3(1-x)+3

= 3 - 3x + 3

= -3x + 6

Now add them together and combine like terms:

f(1-x) + g(1-x)

-2x + 5 + -3x + 6

= -5x + 11
