POV from the angle measure

Angle = 64°

Opposite = 13

Adjacent = x

Step 3: Solve for x

Substitute:                                 tan64° = 13/xMultiply x on both sides:          xtan64° = 13Isolate x:                                    x = 13/tan64°Evaluate:                                    x = 6.34052

what is the expression for f(x) when we rewrite 64^x/4^5x-1 as 4^f(x)

Answers

Answer: f(x)= -2x+1

Step-by-step explanation:

The expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

What is expression ?

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

[tex]\frac{64^x}{4^{5x-1}}[/tex]

So,

Now, to rewrite in form of [tex]4^{f(x)}[/tex],

So,

Rewrite the given expression in the form of 4,

i.e.

[tex]\frac{64^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3)^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3x)}{4^{5x-1}}[/tex]

NOw,

Using Exponent rule,

We get,

[tex]=4^{3x-(5x-1)}=4^{3x-5x+1}[/tex]

On solving we get,

[tex]=4^{-2x+1}[/tex]

So,

[tex]4^{f(x)}=4^{-2x+1}[/tex]

Hence, we can say that the expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

Two numbers have these properties.
Both numbers are greater than 8.
Their highest common factor (HCF) is 8.
Their lowest common multiple (LCM) is 80.
Find the two numbers, writing your answers on one line in the form,
The two numbers are ... and ...​

Answers

Answer:

16 and 40

Step-by-step explanation:

Let the numbers be x and y

HCF is 8, so both numbers are multiples of 8 ⇒ x = 8n, y = 8m

As per property of numbers, the product of numbers is equal to product of their LCM and HCF:

xy = HCF(x,y) × LCM(x,y)

Since LCM(x,y) = 80 we have:

8×80 = xy8×80 = 8n×8m10 = nm

Possible option:

n = 2, m = 5

Then the numbers are:

x = 2*8= 16y = 5*8 = 40

hope it helps

pls mark as brainliest

Answer:

Step-by-step explanation:

You have to figure out what has to multiply by itself to get to that number.

So for example, 121. The square root is more than 10 because 10 times 10 equals 100. It's less than 15 because 15 times 15 is a little over 200. If you have your multiplication tables memorized, you'd know that 11 multiplied by itself is 121. Therefore, the square root to 121 is 11. Hope this helps! (:

Given f(x) = 4x + 1 and g(x) = x2 − 2, which of the following is an expression for f(g(x))?

Answers

The value of the expression of the composite function f(g(x)) = 4x^2 - 3

What are expressions?

Expressions are mathematical statements that are represented by variables, coefficients and operators

How to determine the value of the expression?

The given parameters are:

f(x) = 4x + 1

g(x) = x^2 - 1

The composite function is given as

f(g(x)

The above composite function is calculated as

f(x) = 4x + 1

Substitute x for g(x) in the above function

So, the above function becomes

f(g(x)) = 4g(x) + 1

Substitute x^2 - 1 for g(x) in the above function

So, the above function becomes

f(g(x)) = 4(x^2 - 1) + 1

Evaluate the products in the above equation

So, we have

f(g(x)) = 4x^2 - 4 + 1

Evaluate the sum in the above equation

So, we have

f(g(x)) = 4x^2 - 3

Hence, the value of the composite function f(g(x)) = 4x^2 - 3

Tavon has a gift card of $90 that loses $2 for each 30-day period not used. He has another gift card for $70 that loses $1.50 for each 30-day period not used. What will the value of each card be when they have equal value?

Answers

Answer:

$10

Step-by-step explanation:

Let the number of 30 day periods be x.

[tex]90-2x=70-1.5x \\ \\ 20=0.5x \\ \\ x=40[/tex]

When x=40, the value is 90-2(40)=$10.

The value of each card will be $ 10 after 40 periods, where the value of the first and second cards are equal.

Given data:

Let x represent the number of 30-day periods that have passed since the gift cards were obtained.

For the first gift card with $90 initial value and losing $2 for each 30-day period:

Value of the first card = Initial value - Loss per period * Number of periods

Value of the first card = $90 - $2 * x

For the second gift card with $70 initial value and losing $1.50 for each 30-day period:

Value of the second card = Initial value - Loss per period * Number of periods

Value of the second card = $70 - $1.50 * x

Now, to find when the two cards have equal value x:

Value of the first card = Value of the second card

$90 - $2 * x = $70 - $1.50 * x

On simplifying the equation:

$90 - $70 = $2 * x - $1.50 * x

$20 = $0.50 * x

x = $20 / $0.50

x = 40

After 40 periods of 30 days each, the two cards will have equal value.

Now, determine the value of each card at this point:

Value of the first card = $90 - $2 * 40 = $90 - $80 = $10

Value of the second card = $70 - $1.50 * 40 = $70 - $60 = $10

Hence, both cards will have a value of $10 when they have equal value after 40 periods.

The equation for the cost of the television without remote control is  x = 649 + 125 and its solution is $774.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of television with remote control = $649

It is also given that this amount is $125 more than the cost without remote control.

Suppose x be the cost of television without remote control.

Thus, x = 649 + 125

Answers

Answer:

Question 1-- $250+$2(100)= 350 dollars

Question 2-- $250+$2(150)= 400 dollars

Step-by-step explanation:

To calculate the band's total pay for x number of tickets sold, we can use the following expression Total pay [tex]= $250 + ($2 * x)[/tex] For example, if the band sells 100 tickets, the calculation would be: Total pay [tex]= $250 + ($2 * 100) = $250 + $200 = $450[/tex]

Therefore, the band would make $450 for selling 100 tickets. Similarly, if the band sells 150 tickets, the calculation would be: Total pay [tex]= $250 + ($2 * 150) = $250 + $300 = $550[/tex]

Hence, the band would make $[tex]550[/tex]for selling 150 tickets. This expression takes into account the fixed payment of $[tex]250[/tex] for the band's performance and an additional $2 for each ticket sold. By multiplying the number of tickets sold (x) by $2 and adding it to the fixed payment, we can calculate the band's total earnings.
