Answer:

Step-by-step explanation:

If we define the line QR to be some variable of distance 'x', we can use the relationship of cosine to figure out the length of QR.

Remember, cosine is adjacent of the angle divided by the hypotenuse of the angle. So, if we take this x value over the longest side (hypotenuse), we get the value of cos(theta).

cos(25) = x/7

Multiply both sides by 7 to get:

7*cos(25) = x

Let your calculator do the work to get:

x = 6.3

Answer:

Say you have y=2x. That is direct variation and will always pass through the origin when graphed. When x is multiplied by a number, the y value will also be changed by that number. If you add a y-intercept and change y=2x to, for example, y=2x+2, the x and the y will no longer be related by a constant ratio.

the answer is : a=9 and b=-1

Answer:

c or d

Step-by-step explanation:

To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3

Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.

y=3x+b

2=3*(3)+b

2=9+b

-7=b  So now we know the y-intercept and slope. We just put them together now

y=3x-7

Answer:

x = 3

Step-by-step explanation:

3 ( x + 3 ) = 18

( 3 ) ( x ) + ( 3 ) ( 3 ) = 18

3x + 9 = 18

3x + 9 − 9 = 18 − 9

3x = 9

3x/3 = 9/3

x=3

Answer:

= 2 and 5

Step-by-step explanation:

( 4 - 7x ) + ( 2x - 2 ) = 0

4 - 7x = 2x - 2 = 0

-7x -2x - 2 + 4 = 0

  -5x   - 2   = 0

-5 x = 0                  or             -2 = 0

x = 5                                       x = 2

Answer:

Step-by-step explanation:

The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let 'r' be the radius of the circle. The circumference of the circle will be

C = 2πr units

The radius of the semicircle is given as,

r = 26 cm

Then the circumference of the semicircle is half of the circle. Then we have

C = 1/2 x 2πr

C = πr

At r = 26 cm, then we have

C = 3.14 x 26

C = 81.64 cm

The perimeter of this semi-circle with a radius of 26 cm will be 81.64 cm.

It would take 5 year for the value of the account to reach $99,000.

The worth of a current asset at some point in the future based on an estimated rate of growth is known as future value (FV). For investors and financial planners, the future value is crucial because they use it to predict how much an investment made now will be worth in the future.

Given:

P = $70000

R= 6.8%

SV = $99000

For Compounded Daily

A = P [tex](1+ (R/100)/ 365) ^{365n[/tex]

99000 = 70000 [tex](1+ (0.068/100)/ 365) ^{365n[/tex]

[tex](1+ (0.068/100)/ 365) ^{365n[/tex] = 1.414

[tex](1. 00019)^{365n[/tex] = 1.414

[tex]1.072^n[/tex] = 1.414

and, n=5 years

Hence, it would take 5 year for the value of the account to reach $99,000.

Answer:

The solution to the system of equations is:

[tex]x=10,\:y=4[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}5x-4y=34\\ -x+8y=22\end{bmatrix}[/tex]

Multiply -x+8y=22 by 5:  -5x+40y=110

[tex]\begin{bmatrix}5x-4y=34\\ -5x+40y=110\end{bmatrix}[/tex]

so adding the equations

[tex]-5x+40y=110[/tex]

[tex]+[/tex]

[tex]\underline{5x-4y=34}[/tex]

[tex]36y=144[/tex]

solve 36y = 144 for y:

[tex]36y=144[/tex]

divide both sides by 36

[tex]\frac{36y}{36}=\frac{144}{36}[/tex]

Simplify

[tex]y=4[/tex]

For 5x-4y=34 plug in y=4

[tex]5x-4\cdot \:4=34[/tex]

[tex]5x-16=34[/tex]

Add 16 to both sides

[tex]5x-16+16=34+16[/tex]

Simplify

[tex]5x=50[/tex]

Divide both sides by 5

[tex]\frac{5x}{5}=\frac{50}{5}[/tex]

Simplify

[tex]x=10[/tex]

Therefore, the solution to the system of equations is:

[tex]x=10,\:y=4[/tex]

Step-by-step explanation:

He uses 18.75 grams a day.

We can multiply the amount of grams by the amount of days.

18.75 x 16 = 300

He stops using the bag when he uses 300 grams.

So he uses 1 bag for 16 days

1 bag can last for 16 days.
