Answer:

14.97

Step-by-step explanation:

c^2 - a^2 = b^2

18^2 - 10^2 = x^2

324 - 100 = x^2

x^2 = 224

x = 14.97

A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marin

eduard

The location of the treasure on the treasure map is (b) (7.6,8.8)

The ratio is given as:

$m : n = 5 : 9$

The coordinates of the rock and the tree are:

$Rock =(3,2)$

$Tree = (16,21)$

The x and y coordinates of the location of the treasure are:

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

So, we have:

$(x,y) = (\frac{5 \times 16 + 9 \times 3}{5 + 9},\frac{5 \times 21 + 9 \times 2}{5 + 9})$

$(x,y) = (\frac{107}{14},\frac{123}{14})$

$(x,y) = (7.6,8.8)$

Hence, the location of the treasure is (b) (7.6,8.8)

After 12 years, a deposit of $10,000 into your college account has earned $6,000 in interest payments. What simple interest rate

babymother [125]

Answer:

Step-by-step explanation:

I = PRT/100 where I = interest, P = initial deposit, R = the rate in %, T = number of years.

So substituting the given values:

6000 = 10000*R* 12/100

10000*12*R = 100*6000

R = 100*6000 / (10000 * 12)

R = 600000/120000

= 5%

How do I solve these equations

Sever21 [200]

You need to know the properties of each function.
Tan is opposite (y) over adjacent (x). Sin>0 means that sin is positive, therefore, it is located on either quadrant 1 or 2. Tan=4/3 so it is located in quadrant 1.
The side of the triangle must be Adjacent=3 opposite=4 and hypotenuse=5
Now, you are asked to find the half angle of Cos which is
$\sqrt{\frac{1+cos}{2} }$
By following the formula, cos=3/5 then:
$\sqrt{ \frac{1- \frac{3}{5} }{2} }$ Multiply everything (inside the square $\sqrt{ \frac{5+3}{10} }$ root) by 5
$\frac{2 \sqrt{2} }{ \sqrt{10} }$
$\frac{2 \sqrt{20} }{10}$ Then just simplify
$\frac{ \sqrt{20} }{5}$ The answer is Square root of 20 over 5
