G is in the wrong spot, you have it in (2,2) it needs to go down 4 places to the coordinates (2, -2)

G is in the wrong spot, you have it in (2,2) it needs to go down 4 places to the coordinates (2, -2)

E will be located directly under O and directly across from G. So, it will be at the coordinates (-4, -2)

### A parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal of ___. 5 √(13) √(97)

**Answer:**

A parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal of √(13) units.

**Step-by-step explanation:**

RSTU is parallelogram. The vertices of the parallelogram are R(1, -1), S(6, 1), T(8, 5), and U(3, 3).

Two opposite vertices are connected by the diagonal of a parallelogram. So, RT and SU are two diagonal.

Distance formula:

Using this formula we get

**Therefore the parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal SU of √(13) units.**

### A line has a slope of 1/4 and passes through point 0.4-1/2. What is the value of the y-intercept?

m=1/4 (given) & it passes through (0.4, - 0.5)

Let's calculate b; -0.5 = (1/4)(0.4) + b

-0.5 =0.25(0.4) + b

-0.5 - 0.1 = b -0.6

y= 0.25x - 0.6

y intercept is calculated for x=0

Then y intercepts =-0.6

### Graph the pH function using the graphing utility. Then answer the questions. What is the pH of lemon juice that has a hydrogen ion concentration of 0.01 moles per liter? The pH is??

**Answer:**

**pH = 2**

**Step-by-step explanation:**

To graph the pH function :

The range of the pH function varies from 1 to 14

And the concentration of hydrogen ion goes from 0 to 1

Taking pH value on y-axis and concentration of hydrogen ion on x-axis, The resultant graph is attached below :

Given : Concentration of hydrogen ion = 0.01

Now, pH = -log(0.01)

*Answer: =50 *

*Explanation: An unknown leg of a right triangle can be found using the Pythagorean theorem. Pythagorean theorem: a²+b²=c²*

a²=14²+48²

a²=14²=14*14=196

a²=48²=48*48=2304

a²=196+2304

a²=196+2304=2500

a²=2500

a²=(25*100)=2500

a=5*10=50

*A=50*

### A statue creates a shadow that is 30 feet long. the angle of elevation of the sun is 50 degrees. How tall is the statue and how would i calculate that?

first, the angle of elevation, the shadow and the statue form an right triangle.

so, we know that for computing tangent, we use the main formula:

Tan = opposite side / adjacent side

let x be the length of the statue, it is the opposite side

30 feet long is the adjacent side

therefore,

tan50°= x /30, 1.19 * 30= x, and the x=35.75 feet
