Consider the equation y=2^x+1-7

Answer: x = 41

Step-by-step explanation:

Since x and y are complementary angles, that means x + y = 90 degrees.

We are given that y = x + 8

We can substitue y as x + 8 in the complementary angle equation.

Therefore, we get x + x + 8 = 90

2x = 82

x = 41

Answer: (x°)° * (9x-8)*1

Step-by-step explanation: With the given functions, we can simplify this easily. g(x) = x°, so then multiplying the two functions together, is easy since they are simple equations. You get (x°)° * (9x-8) * 1 (since 1 was apart of the g function equation)

Answer:

100 (I believe)

Step-by-step explanation:

The length would be 20
20 x 2 (because we have two sides) is 40

the width would have to be 5 then

5x2 (because we have to sides) is 10

5x4 is 20 (Showing that the length is 4 times the width)

40 + 10 = 50 (Which is the perimeter)

Since we know the length is 20 and the width is 5

we just do

20 * 5 = 100

Answer:

L = 20

Width = 5

Step-by-step explanation:

"The perimeter of the rectangle is equal to 2 times length + 2 times width:

P = 2L + 2W

We know that length is 4 times the width, so L = 4 W

We can now replace l by 4W in the equation of the perimeter:

P = 2L + 2W = 50

P = 2(4W) + 2W = 50

P = 8W + 2W = 50

P = 10W =50

So W = 50 /10

W = 5

And L = 4W

L= 4 (5)

L = 20"

Angle of depression = 51° (to nearest degree)

Step-by-step explanation:

Using tan trig ratio (where x is the angle, O is the side opposite the angle and A is the side adjacent to the angle)

[tex]tan(x)=\dfrac{O}{A}=\dfrac{9.3}{7.4}=\dfrac{93}{74}\\\\\implies x=\arctan\left(\dfrac{93}{74}\right)=51.49 \textdegree[/tex]

So angle of depression is 51.49° (to nearest hundredth)

Answer: 82 degrees

Step-by-step explanation:

The sum of the angles in a triangle is 180 degrees which is a straight angle.

Let the unknown third angle be x.

Therefore, 86 + 12 + x = 180

98 + x = 180

x = 82

Answer:

The heartened are in cm so it's L x W x H which would be 7 x 4 x 2.5 = 70cm cubes.

But because our cubes are 1/2cm cubes, each 1cm cube holds 8 1/2 cm cubes. (2 x. 05 long by 2 x 0.5 wide by 2 x 0.5 high)

So we need to multiply our 70 cm cubes by 8.

70x 8 = 560 1/2 cm cubes.

The factors of the equation [tex]\rm x^3+x^2+x+1\\\\[/tex] are [tex]\rm (x^2 +1)(x +1)[/tex].

A factor is a number that divides another number leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

Given

The equation is;

[tex]\rm x^3+x^2+x+1[/tex]

The factors of the equation are given by;

[tex]\rm = x^3+x^2+x+1\\\\ = x^2(x +1) + 1( x +1 )\\\\= (x^2 +1)(x +1)[/tex]

James's current balance on his credit card is $900.

This amount represents the card's balance before the current charge of $1,500 and the finance charge of $60.

A credit card balance is the amount of the charges made on a credit card, including the finance charges, and therefore, owed to a credit card company.

Current current balance = $x

APR (Annual Percentage Rate) of interest = 30%

Monthly APR = 2.5% (30%/12)

Current purchase for the month = $1,500

Finance charge for the month = $60

Finance charge for the current purchase = $37.50 ($1,500 x 2.5%)

Finance charge for the current balance = $22.50 ($60 - $37.50)

The current balance that attracts the finance charge of $22.50 will be $900 ($22.50/2.5%).

Alternatively:

Since the monthly APR is 2.5% and the finance charge is $60 for the month, the balance at the end of the month is $2,400 ($60/2.5%).

Thus, the current balance on James' credit card is $900 ($2,400 - $1,500) while the end-of-the-month balance is $2,460 ($900 + $1,500 + $60).

Work Shown:

Slope = rise/run

Slope = (change in y)/(change in x)

Slope = (2-p)/(-10-(-6))

Slope = (2-p)/(-10+6)

Slope = (2-p)/(-4)

Set this equal to the stated slope -1/6 and solve for p

(2-p)/(-4) = -1/6

6(2-p) = -4(-1)

12-6p = 4

-6p = 4-12

-6p = -8

p = -8/(-6)

p = 4/3

Answer:

13,260.22 mm²

Step-by-step explanation:

the area of the shaded region is the area of the larger circle minus the area of the smaller one

to find the area of the larger we will use half of 62 plus 41 as the radius:

Area (larger) = 3.14(72)²

= 16,277.76

Area (smaller) = 3.14(31)²

= 3,017.54

Area (shaded region) is 16277.76 - 3017.54 = 13,260.22 mm²

25Q +10D = 475 (miltiplied all by 100 to avoid decimals)

Multiply the first by -10(to eliminate D)

    -10Q - 10D = - 310

     25Q+10D = 475

ADD BOTH(  D will cancel)

15Q = 165
