On a coordinate plane, triangle R S T has points (negative 5, 6), (3, 4), and (negative 2, 2).Which expression can be used to find the area of triangle RST?

(8 ∙ 4) - One-half (10 + 12 + 16)
(8 ∙ 4) - (10 + 12 + 16)
(8 ∙ 4) - One-half (5 + 6 + 8)
(8 ∙ 4) - (5 - 6 - 8)

Answers

Based on the coordinate plane, a mathematical expression which can be used to find the area of triangle RST is: A. [(8 × 4) - 1/2 × (10 + 12 + 16)].

What is a triangle?

A triangle can be defined as a two-dimensional geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.

How to calculate the area of a triangle?

Mathematically, the area of the triangle is given by the formula:

Area = (1)/(2)* base * height

In this scenario, the mathematical expressions that would be used to find the area of triangle RST with points (-5, 6), (3, 4) and (-2, 2) are given by:

Area of rectangle = LW = 8 × 4

Area of triangle 1 = 1/2 × (2 × 5) = 1/2 × 10

Area of triangle 2 = 1/2 × (3 × 4) = 1/2 × 12

Area of triangle 3 = 1/2 × (2 × 8) = 1/2 × 16

The area of triangle RST = [(Area of rectangle) - 1/2 × (Area of triangle 1 + Area of triangle 2 + Area of triangle 3)].

Substituting the parameters into the formula, we have;

The area of triangle RST = [(8 × 4) - 1/2 × (10 + 12 + 16)]

Step-by-step explanation:

Find the range of {(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}.

Answers

Answer: The range is the output of our data, in standard notation represented as (x,y) where x is the input and y the output.

So the values of x are the domain, and the values of y are the range.

The set you give is :  {(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}

You can see that the range is : {-3, 5.9, 8.3}

Notice that in the set, the point y = -3 appears two times (in different pairs), but in the range only one, because you cant repeat the same value in one set.

range is output or y
(x,y)
the range is the 2nd number
when it repeats, don't list again
range=-3,5.9,8.3

The first quartile of a data set is 51, and the third quartile is 67. Which of these values in the data set is an outlier?A. 49
B. 83
C. 93
D. 29

Answers

Given:
Quartile 1 = 51
Quartile 3 = 67

Interquartile range = Q₃ - Q₁
IQR = 67 - 51
IQR = 16

Inner fence of the data set:
16 x 1.5 = 24

67 + 24 = 91
51 - 24 = 27

Boundaries of inner fence are 27 and 91

16 x 3 = 48

67 + 48 = 115
51 - 48 = 3

Boundaries for outer fence are 3 and 115

C. 93 is an outlier. It is a minor outlier based on the boundaries of the inner fence. 

Answer: 93

What are the approximate solutions of 2x2 + 9x = 8 to the nearest hundredth?a. x ≈ 1.22 and x ≈ 3.28
b. x ≈ −0.76 and x ≈ 5.26
c. x ≈ −1.22 and x ≈ −3.28
d. x ≈ −5.26 and x ≈ 0.76

Answers

Answer:

The roots of the equations are x ≈ -5.26 and x ≈ 0.76 .

Option (d) is correct.

Step-by-step explanation:

Formula for the roots is given by .

x = \frac{-b \pm \sqrt{b^(2) -4ac}}{2a}

As the equation in the form

2x^(2) + 9x - 8 = 0

As the equation in the form ax² + bx + c = 0

a = 2, b= 9 , c = -8

Put in the formula

x = \frac{-9 \pm \sqrt{9^(2) -4* 2* -8}}{2* 2}

x = (-9 \pm √(81 + 64))/(4)

x = (-9 \pm √(145))/(4)

√(145) = 12.04

Thus First roots be

x = (-9 - 12.04)/(4)

x = (-21.04)/(4)

x ≈ -5.26

The second root be

x = (-9 + 12.04)/(4)

x = (3.04)/(4)

x ≈ 0.76

Therefore the roots of the equations are x ≈ -5.26 and x ≈ 0.76 .

Option (d) is correct.

What is the volume of the right prism? A.
166 in3

B.
140 in3

C.
64 in3

D.
16 in3

Answers

I saw the image that should have been included in this problem.

It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.

The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches

volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³  Choice B.

360

for me it was 360.
