The height (in inches) of a candle, h(t), is modeled by the function h(t) = 8 - t, where t is the amount of time the candle has been burning. What is the meaning of the y-
intercept of the graph of the function?
A. The amount of time the candle has been burning
B. The height of the candle when it starts to burn
C. The maximum amount of time the candle can burn
D. The height of the candle after it is finished

Answers

Answer 1

Answer:B.the height of the candle when it starts to burn

Step-by-step explanation:

Answer 2

The y - intercept is 8. It represents the height of the candle when it starts to burn.

What is the general equation of a Straight line?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have the height (in inches) of a candle, h(t), is modeled by the function h(t) = 8 - t, where t is the amount of time the candle has been burning.

We have -

h(t) = - t + 8

h(t) = - t + 8

Here, the y - intercept is 8. It represents the height of the candle when it starts to burn.

Therefore, the y - intercept is 8. It represents the height of the candle when it starts to burn.

Minimum, Vertex(1,-7) and sorry what do you mean by aos? i dont get that please type in the comments I'll answer that too. Hope you understand the rest

Step-by-step explanation:

The vertex of a parabola means the stationary point/turning point which is denoted by the following:

[tex]x=\frac{-b}{2a} \\[/tex]

and for y we just simply put the value of x that we get into the equation so lets get started

The equation [tex]y=x^2-2x-6[/tex] is a quadratic equation

and if we compare it by the standard form [tex]y=ax^2+bx+c[/tex] we get the following values

a=1 , b=-2 , c=-6

and now for the vertex

[tex]x=\frac{-b}{2a}[/tex]

[tex]x=\frac{-(-2)}{2(1)} \\x=\frac{2}{2} \\x=1[/tex]

and now for y

[tex]y=x^2-2x-6\\y=(1)^2-2(1)-6\\y=1-2-6\\y=-7[/tex]

so the vertex is (1,-7)

and the graph is minimum not maximum because the value of a is greater than 0 if the value of a>0 then the graph is minimum and if the value of a<0 meaning a is negative the graph is maximum and here in the equation a=1 which means a>0 then our graph is minimum.

x = [tex]\frac{29}{7}[/tex]

Step-by-step explanation:

Given f(x) = 7x + 2 and f(x) = 31 then equate the right sides

7x + 2 = 31 ( subtract 2 from both sides )

7x = 29 ( divide both sides by 7 )

x = [tex]\frac{29}{7}[/tex]

Answers

Answer: The angles are 30 30, 150, 150

Step-by-step explanation: Two lines intersect means they cross. According to the vertical angle theorem, angles that are across are the same, a line is 180 degrees so it means the angles that make up the supplementary pair add up to 180(180-30=150). So there are 2 150 degree angles and 2 30 degree angles

Answers

Answer:

x = 1/2

Step-by-step explanation:

Step 1: Write equation

-4x + 6(4x - 3) = -8

Step 2: Solve for x

Distribute 6: -4x + 24x - 18 = -8Combine like terms: 20x - 18 = -8Add 18 to both sides: 20x = 10Divide both sides by 20: x = 1/2

Step 3: Check

Plug in x to verify it's a solution.

Substitute: -4(1/2) + 6[4(1/2) - 3] = -8Evaluate: -2 + 6[2 - 3] = -8Evaluate: -2 + 6(-1) = -8Evaluate: -2 - 6 = -8Evaluate: -8 = -8

Step-by-step explanation:

the answer is 50 because 2x-=76 is k :)

Answer:

k (oats in cups) = 25 (grams of almonds)

Step-by-step explanation:

If you look at the coordinates given in the question (1,k) where we are told to find k.

A coordinate is a pair of one x and y value, an input and output in a relationship.

2d coordinates are in the form of (x,y), this means that (1,k) is representing what k will be when x is 1. So to find k, we must look at where y (the amount of almonds in this instance) is when x (the oats) is 1.

This graph looks to be y = 25x.

Where y is the oats in cups, and x is the grams of almonds. This is a proportion which means that there are 25 grams of almonds for every 1 cup of oats.

evaluate the function for f(-3), f(x)=3x+5

Answers

Answer:

-4

Step-by-step explanation:

Since we know that -3 takes the place of x in f(x), we can sub in -3 for all x's in the equation.

Using this information, we now have F(-3)=3(-3)+5

Once you solve the right side of the equation, you get f(-3)=-4

if you were to plot this, the points would be (-3,-4), however I believe you're not trying to, so the answer would be -4.

Find the Highest Common Factor (HCF) of 196 and 12

Answers

Answer:

The greatest common factor is 4

Step-by-step explanation:

1.Find the prime factorization of 12

         a) 12 = 2 × 2 × 3

2.Find the prime factorization of 196

         a) 196 = 2 × 2 × 7 × 7

To find the GCF, multiply all the prime factors common to both numbers:

          a)GCF=2x2

Therefore, GCF = 2 × 2

GCF = 4

The greatest common factor of the numbers 196 and 12 is 4.

What is the greatest common factor?

The largest factor of the two numbers which divides both numbers is called as greatest common factor or GCF. The greatest common factor is the largest number which can divide both the numbers.

1. Find the prime factorization of 12

12 = 2 × 2 × 3

2. Find the prime factorization of 196

196 = 2 × 2 × 7 × 7

To find the GCF, multiply all the prime factors common to both numbers:

GCF=2x2

GCF=4
