Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?

Nastasia [14]

Answer:

d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

Step-by-step explanation:

The distance formula is d= $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }$ .

6 is $x_{2}$ , 9 is $x_{1}$ , 3 is y $_{2}$ , and -2 is y $_{1}$ .

When you plug these into the formula, you get d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

Which statements are true about the ordered pair (2, 3) and the system of equations?

vlabodo [156]

3x + 4y = 18......(2,3)
3(2) + 4(3) = 18
6 + 12 = 18
18 = 18...correct

2x - 2y = 2....(2,3)
2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2...incorrect

when (2,3) is subbed into equation 1, it is true
when (2,3) is subbed into the second equation, it is false
the ordered pair (2,3) is not a solution to the system of linear equations

What is 26.553 rounded to the nearest hundred?

valentinak56 [21]

Answer:

26.55

Step-by-step explanation:

Compound Interest Rate Formula: $\displaystyle A = P(1 + \frac{r}{n})^{nt}$

A is final amount
P is principle amount
r is rate
n is compound rate
t is time (in years)

Step-by-step explanation:

Step 1: Identify Variables

P = $1900

r = 3% = 0.03

n = 4

Step 2: Solve for A

Substitute [CIRF]: $\displaystyle A = 1900(1 + \frac{0.03}{4})^{4(6)}$
(Parenthesis) Divide: $\displaystyle A = 1900(1 + 0.0075)^{4(6)}$
(Parenthesis) Add: $\displaystyle A = 1900(1.0075)^{4(6)}$
(Exponents) Multiply: $\displaystyle A = 1900(1.0075)^{24}$
Exponents: $\displaystyle A = 1900(1.19641)$
Multiply: $\displaystyle A = 2273.19$

Two angles of the adjacent side of a trapezoid should have a total angle of 180. In You can get this equation:
∠OPM + ∠PMN= 180
∠OPM = 180- ∠PMN

∠OPM = 3(∠PMN) -10
180- ∠PMN= 3∠PMN -10
180+10= 3∠PMN + ∠PMN
4 ∠PMN= 190
∠PMN= 47.5

∠OPM + ∠PMN= 180
∠OPM + 47.5= 180
∠OPM = 180-47.5= 132.5
