Answer:
A. {-1, -3, -7, -9}
Step-by-step explanation:
Plug all 4 points into the equation -2x-5.
-2(-2) - 5 = 4 - 5 = -1
(-2, -1)
-2(-1) - 5 = 2 - 5 = -3
(-1, -3)
-2(1) - 5 = -2 - 5 = -7
(1, -7)
-2(2) - 5 = -4 - 5 = -9
(2, -9)
The y-values make up the range, making the answer A, {-1, -3, -7, -9}
Answer:
A. {-1,-3,-7,-9}
Step-by-step explanation:
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
...................................................................................................................................................
Answer:
{-1, -3, -7, -9} is the range of the function f(x)
Step-by-step explanation:
Domain is the set of all complete possible values of x variable.
Range is the set of all values of f(x)
Given the function:
.....[1]
Domain: {-2, -1, 1, 2}
For x = -2,
Substitute in [1] we have
Similarly ,
For x = -1
For x = 1:
For x = 2
Therefore, the range of f(x) = {-1, -3, -7, -9}

Answer:
6*6+16*20
=320+36
=356 so it's C
Answer:
C: 356 sq ft.
Step-by-step explanation:
Imagine a rectangle filling the empty space in the polygon.
Using this, we get 440 sq ft.
Now subtract the area that you filled in.
440-(14x6)=A
440-84=A
356=A

In the isosceles trapezoid below,
x = [? ]°
5x-20°
2x+37°
Answer:
x = 19
Step-by-step explanation:
The lower base angles in an isosceles trapezoid are congruent , then
5x - 20 = 2x + 37 ( subtract 2x from both sides )
3x - 20 = 37 ( add 20 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19
Solve for x. Round your answer to the nearest tenth.
Answer:
17.5
Step-by-step explanation:
[tex]15^{2}+9^{2}= 306\\[/tex]
[tex]\sqrt{306} = 17.5[/tex]
Answer:
x ≈ 17.5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² = 9² + 15² = 81 + 225 = 306 ( take the square root of both sides )
x = [tex]\sqrt{306}[/tex] ≈ 17.5 ( to the nearest tenth )
8. Find the area of the triangle. (1 point) 16 ft 62 ft Not drawn to scale.
Answer:
Hello! Answer: 496
Step-by-step explanation:
When finding area for triangles we have to do base x height then divide by 2 so
62 x 16 = 992
992 ÷ 2 = 496
So 496 is our answer!
Answer:
A - 496
Step-by-step explanation:
formula for area of a triangle
[tex]a = \frac{bh}{2} [/tex]
where b = base length and h = height
The triangle shown has a base length of 62 ft and a height of 16 ft
That being said we plug in the given values into the formula
[tex]a = \frac{62 \times 16}{2} \\ 62 \times 16 = 992 \\ \frac{992}{2} = 496[/tex]
Hence the area of the triangle is 496 square feet

What is the potential energy of a 500kg elevator that is 4.0m high from the floor?
Answer:
19,600 JStep-by-step explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
We have
PE = 500 × 9.8 × 4
We have the final answer as
19,600 JHope this helps you
An actor, Bob, wants to gain weight to look the part for his role as an overweight truck driver in an upcoming movie. He decides to add servings of banana splits (S) and bacon rolls (B) to his diet. Each serving of S is 1,000 calories and each serving of B is 500 calories. Bob has a history of health problems and his doctor has recommended that he needs to control his cholesterol and sugar levels in his food intake. Each serving of S contains 1 unit of cholesterol and 3 units of sugar. Each serving of B contains 4 units of cholesterol and 1 units of sugar. His doctor recommends that his cholesterol be no larger than 10 units and his sugar levels should be at least 2 units and no larger than 9 units. What should be the objective function (C) to select the optimal choice of Sand B in order for Bob to ingest as many calories as possible? A. C = 105 + 5B B. C = 1000S + 500B C. C = S+BD. None of the above
Answer:
[tex]C = 1000S + 500B[/tex]
Step-by-step explanation:
Given
[tex]S = Banana\ Splits[/tex]
[tex]B=Bacon\ Rolls[/tex]
Reading through the question, we have:
Number of calories per serving:
[tex]S \to 1000[/tex]
[tex]B \to 500[/tex]
Let
[tex]x = Cholesterol[/tex]
[tex]y =Sugar[/tex]
So, we have:
Each serving of S
[tex]x \to 1S[/tex]
[tex]y \to 3S[/tex]
Each serving of B
[tex]x \to 4B[/tex]
[tex]y \to 1B[/tex]
Recommendation
[tex]x \to \le 10[/tex] - i.e. not more than 10 units of cholesterol
[tex]y \to \ge 2 \& \le 9[/tex] i.e. At least 2units but not more than 9 units of sugar
So, the constraints are:
[tex]S + 4B \le 10[/tex]
[tex]3S + B \ge 2[/tex]
[tex]3S + B \le 9[/tex]
Recall that the calories per serving is:
[tex]S \to 1000[/tex]
[tex]B \to 500[/tex]
Hence, the objective function is:
[tex]C = 1000S + 500B[/tex]

Una parcela de forma cuadradra mide 1089km2 de superficie cuantos metros mide el lado de la parcela
Respuesta:
3.3 × 10⁴ m
Explicación paso a paso:
Paso 1: Información provista
Superficie de la parcela cuadrada (S): 1089 km²
Paso 2: Determinar la longitud del lado (l) de la parcela
Podemos determinar la superficie de un cuadrado usando la siguiente fórmula.
S = l²
l = √S = √1089 km² = 33 km
Paso 3: Convertir "l" a metros
Vamos a usar el factor de conversión 1 km = 10³ m.
33 km × 10³ m/1 km = 3.3 × 10⁴ m

What can it be solved by?
A ball is kicked upward with an initial velocity of 56 feet per second. The ball's height h (in feet) can be expressed as a function of time t (in seconds) by the equation h = -16t2 + 56t. How much time does the ball take to reach its highest point?
1.75 seconds B) 2.50 seconds C) 2.75 seconds D) 3.50 seconds
Answer:
1.75
Step-by-step explanation:
h(t) = -16t² + 56t
h'(t) = -32t + 56
To find time at max height equate h' to 0
0 = -32t + 56
t = 56/32 = 1.75 s
It takes 1.75 s to reach max highest point

20 people each bring 3 food dishes to an awards banquet. The dishes are shared equally by 180 people at the banquet. How many people share 1 food dish?
Answer:
3 people
Step-by-step explanation:
If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods
If the dishes are shared equally by 180 people at the banquet, then;
60foods = 180 people
1 food = x
Cross multiply
60* x = 180
60x = 180
x =180/60
x = 3
Hence 3 people will share 1 dish
