Simplify 7^8 X 7^3 X 7^4--------------------- 7^9 X 7^5

Answers

Answer 1

Step-by-step explanation:

According to the power law of indices, when base numbers are the same and multiplying,add their exponents but when base numbers are the same and dividing, subtract their exponents.

Applying the above rule to the numerators,we have 7^(8+3+4)=7^15

Applying to the denominators we have,

7^(9+5)=7^14

Now we have 7^15/7^14=7

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use trig to find the missing length.

Step 2: Identify Variables

POV from the angle measure

Angle = 57°

Opposite = x

Adjacent = 6

Step 3: Solve for x

Substitute:                    tan57° = x/6Isolate x:                       6tan57° = xEvaluate:                       9.23919 = xRewrite:                        x = 9.23919

9514 1404 393

Answer:

x ≈ 9.24H ≈ 11.02

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships.

  Tan = Opposite/Adjacent

  tan(57°) = x/6

  x = 6·tan(57°) ≈ 9.24

__

The complete solution of the triangle will also find a value for H.

  Cos = Adjacent/Hypotenuse

  cos(57°) = 6/H

  H = 6/cos(57°) ≈ 11.02

minutes will it take Graham and Max to meet at
the same altitude ?
a. Equation:
1
2
. Solution:
2. At what altitude will Graham and Max meet?
3

Answers

Answer:  Equation 1 to find the time: A₁ - r₁t = A₂ + r₂t  Solve for t

14040 - 50t = 12500 + 20t     t is the number of minutes

Equation 2 to find the altitude: A₁ - r₁t = A₂ + r₂t  A₁ and r₁ are Grahams initial altitude and rate. Use given rates, calculated time and solve for A.

A₂ and r₂ are Max's initial altitude and rate.

They will meet in 22 minutes

They will meet at 12940 ft altitude

Step-by-step explanation:  Their original heights plus/minus the altitude change per minute (rate) and the time will be equal when they meet.

14040 - 50t = 12500 + 20t    subtract 12500 from both sides; add 50t to both sides.

14040-12500 = 20t + 50t

1540 = 70x

22 = t  They will meet in 22 minutes.  

To get the altitude where they meet, Multiply the time by the rate for each climber. Add or subtract per equation: A₁ - r₁t = A₂ + r₂t

14040 - 22(50) = 12500 + 22(20)

Graham: 22 min × 50ft/min = 1100 ft

Subtract from his starting altitude:

14040 - 1100 = 12940 ft

Max: 22 min ×20 ft/min = 440 ft

Add to his starting altitude

12500 + 440 = 12940 ft

Answer:

Answer:

M=22, hope this helps

Step-by-step explanation:

Set up Graham's altitude function A(m):

A(m) = 14040 - 50m <-- we subtract for descending

Set up Max's altitude function A(m):

A(m) = 12500 + 20m <-- we add for ascending

Set the altitudes equal to each other to solve for m:

14040 - 50m = 12500 + 20m

We type this equation into our search engine to solve for m and we get:

m = 22

What is the slope for this (-1,5) (2,-4)

Answers

Slope = -[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

To find the slope, you have to calculate the rise over run between two points.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{2-(-1)}{(-4)-5}[/tex]

     = [tex]\frac{3}{-9}[/tex]

A car traveled 180 miles at a constant rate. Write an equation that would make it easy to find the rate at which the car was traveling in miles per hour r, if it traveled for t hours

Answers

Answer:

A. Distance travelled at constant rate = 180 miles

Rate of travel (r) = distance travelled (d) /time (t)

Travel time (hrs) ==> rate of travel (miles/hr)

5 ==> 180/5 = 36

4.5 ==> 180/4.5 = 40

3 ==> 180/3 = 60

2.25 ==> 180/2.25 = 80

B. t = time travelled in hrs,

r = rate (miles/hr)

d = distance travelled = 180

Answer:

180/t

Have a great day!

The number 8 % as a fraction in the simplest from is 2/25

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the value of A is = 8 %

So , the equation will be

The value of A = 8 %

Now , the value 8 percentage can be written as a fraction of 100

So , the value of A will be

The value of A = 8/100

Now , on dividing the numerator and denominator by 4 , we get

The value of A = 2 / 25

So , the value of A in the simplest form of the number A is 2/25

Hence , The number 8 % as a fraction in the simplest from is 2/25

Describe the transformation of the graph y = (x)^3 + 6

Answers

The graph of y = x^3 + 6 is the result of shifting y = x^3 up 6 units

If f(x) = x^3, then g(x) = f(x) + 6 leads to g(x) = x^3+6.

The reason we shift up 6 is because we're adding 6 to the y coordinate.

Think of y = f(x), so f(x)+6 is the same as y+6.
