Answer: x=5

Explanation:
sin=opposite side/hypotenuse
The opposite side is x and the hypotenuse is 10.
So your equation is: sin(30)=x/10
In order to get x by it self times ten to each side of the equation.
10 x sin(30)= x
Put 10 x sin(30) into graphing calculator and make sure your calculator is set to degrees.
Your answer:
5= x

The coordinate of the partition c on the line segment is (1.2, -4.7)

<h3>How to determine the coordinates of the partition?</h3>

The coordinates are given as:

A = (7,-2)

B = (-8,-9)

m:n = 5:8

The coordinate of the partition is calculated using:

$(x,y) = \frac{1}{m + n} * (mx_2 + nx_1, my_2 + ny_1)$

So, we have:

$(x,y) = \frac{1}{5 + 8} * (5 * -8 + 8 * 7, 5 * -9 + 8 * -2)$

Evaluate the sum and products

$(x,y) = \frac{1}{13} * (16, -61)$

Evaluate the product

(x,y) = (1.2, -4.7)

Hence, the coordinate of the partition on the line segment is (1.2, -4.7)

The value of a small airplane depreciates exponentially every year after it is purchased. The value, in thousands of dollars, a(

ratelena [41]

Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.

<h3>Exponential function:</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

In this problem, the function for the value of the airplane after t years is given by:

$A(t) = 131.5(0.8)^t$

Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.

faltersainse [42]

Answer with explanation:

It is given that, there is positive correlation between drinking coconut milk and eating potato chips.

→Correlation coefficient is denoted by r.

→The value of r lies between , -1 and 1 which is represented as , -1 ≤r≤1.

→Correlation that is relation between two variables is said to be strongly positive, if r is equal to 1, and it is said to be strongly weak, if it is equal to -1 , and said to have no association if r=0.

→ The meaning of positive correlation is that value of r, is greater than >0.8 but less than 1.

The two variables which are positively correlated ,can have following relationship.

1. With increase in one other increases.

2.With decrease in one other decreases.

3. Slope will be a linear that is a straight line not passing through origin.
