Help guys plzzz asapppp

nignag [31]

sin(x) = opp/hyp
cos(x) = adj/hyp
tan(x) = opp/adj

sin(x) = 3.9/8.1
sin(x) = 0.481

Inverse sin of 0.481 = 28.8 degrees

Each answer should be between 0 and 90 :)

Math help questions <br>

Evgen [1.6K]

After 1 year, the initial investment increases by 7%, i.e. multiplied by 1.07. So after 1 year the investment has a value of $800 × 1.07 = $856.

After another year, that amount increases again by 7% to $856 × 1.07 = $915.92.

And so on. After t years, the investment would have a value of $\$800 \times 1.07^t$ .

We want the find the number of years n such that

$\$856 \times 1.07^n = \$1400$

Solve for n :

$856 \times 1.07 ^n = 1400$

$1.07^n = \dfrac74$

$\log_{1.07}\left(1.07^n\right) = \log_{1.07}\left(\dfrac74\right)$

$n \log_{1.07}(1.07) = \log_{1.07} \left(\dfrac74\right)$

$n = \log_{1.07} \left(\dfrac74\right) = \dfrac{\ln\left(\frac74\right)}{\ln(1.04)} \approx \boxed{8.3}$

Graph the line that passes through the points (-4,-6) and (-2,-7) and

Komok [63]

Answer:

$y=-\frac{1}{2}x-8$

Step-by-step explanation:

$(-4,-6)(-2,-7)$

Step 1. Find the slope (by using the slope-formula)

m = slope

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-7--6}{-2--4}$

$m=\frac{-1}{2}$

$m=-\frac{1}{2}$

Step 2. Create the equation of a line that has a slope of $-\frac{1}{2}$

$y=-\frac{1}{2} x+b$

Step 3. Find the y-intercept

To do this, use any of the two points and substitute their x and y values

$y=-\frac{1}{2}x+b$

point: $(-2,-7)$

$(-7)=-\frac{1}{2}(-2)+b$

$(-7)=1+b$

$b=-7-1$

$b=-8$

Step 4. Write the equation in Slope-intercept form

$y=mx+b$

$y=-\frac{1}{2} x-8$
