Here is a balanced hanger diagram:
A circle has a mass of 3 grams and a square has a mass of 2 grams.
Which is the mass of a triangle?
a. 9/5 grams
b. 715 grams
c. 3 grams
d. 11 grams
Answer:
D
Step-by-step explanation:
11 grams because the the most logical.
Option C. 3 grams is the answer.
Mass given,
One circle = 3 gramsOne square = 2 gramsFor the balanced hanger diagram,
Mass on left arm = Mass on right armMass on left arm = 2.(one triangle) + 6.(one square) + 3.(one circle)
Mass on right arm = 5.(one triangle) + 3.(one square) + 2.(one circle)
Equation for the balanced hanger,
2.(one triangle) + 6.(one square) + 3.(one circle) = 5.(one triangle) + 3.(one square) + 2.(one circle)
Now solve this equation,
(6 - 3).(one square) + (3 - 2).(one circle) = (5 - 2).(one triangle)
3.(one square) + 1.(one circle) = 3.(one triangle)
3.(2) + 1.(3) = 3.(one triangle)
6 + 3 = 3.(one triangle)
One triangle = 3 grams
Therefore, Option (C) will be the correct option.

An insurance company offers a term life insurance policy with a renewable premium.
The first year premium is $900
The premiums increase 5.5% each year,
[tex]A=Pe^r^t[/tex]
5.5%=5.5/100 =0.055
[tex]A = 900(e)^0^.^0^5^5^\times^7[/tex]
[tex]A=900e^0^.^3^8^5[/tex]
A=900×1.46

Create a table for the equation with a y-intercept of 15 and a slope of -5. What is the output when x is -10?
x y
-2
-1
0
1
2
-6 ?
Answer:
The output is 65 when x is -10.
Step-by-step explanation:
y=mx+b is the easiest form to understand visually what the slope and intercept is.
m is the slope and b is the y-intercept. Replace both of these variables respectively with their appropriate values. In this case, the slope (m) is -5 and y-intercept is 15.
Equation looks like this: y=-5x+15
What is the output when x is -10? Replace x with 10, and your output is the y value.
[tex]y=-5(-10)+15\\y=50+15\\y=65[/tex]

Step-by-step explanation:
A motorboat moves across a lake at a constant speed. When it begins, it is 48
km from the shore. After 10 minutes, it is 18 km from the shore. Which
function describes the motorboat's distance from the shore?
O A. y = 10x+48
B. y=-3x + 48
O c. y=-10x + 48
O D. y = 3x + 48
Answer:
b
Step-by-step explanation:
The function describes the motorboat's distance from the shore is y=-3x + 48. So, the correct option is B.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, a motorboat moves across a lake at a constant speed.
Let x be the number of minutes and y be the total distance.
When it begins, it is 48 km from the shore.
Now, (x₁, y₁) =(0, 48)
After 10 minutes, it is 18 km from the shore.
So, (x₂, y₂) =(10, 18)
We know that, Slope(m) =(y₂-y₁)/(x₂-x₁)
= (18-48)/(10-0)
= -30/10
= -3
Substitute, (x, y)=(0, 48) and m=-3 in y=mx+c, we get
48=-3(0)+c
c=48
Substitute, c=48 and m=-3 in y=mx+c, we get
y=-3x+48
Therefore, option B is the correct answer.

a negative trend would start at the top left and go town the bottom right
this is an example of no trend
Step-by-step explanation:
a "trend" shows an increasing or decreasing relationship between the x and y values, in this they don't have any sort of relationship. you can tell by the repeating y values for multiple different x-values, or the repeating x-values for multiple different y-values.

Answer:
Step-by-step explanation:
first just look at the graph
its very obvious its a linear graph because it is going up in a straight line at a steady pace
so we can then just ignore the answers that say its not a linear function
then since its straight and not curved (curved graphs or parabolas are found when x has an exponent) its obvious it cant be one of the equations with x^2
so we are left with one the final answer
its equation is y = x + 2 and it is a linear function
