From 1990 to 1996, the consumption of poultry per capita is modeled by: y=-.2125t^2 + 2.615t+56.33 where t=0 corresponds to 1990. What was the per capita poultry consumption in 1992?

Answers

Answer:

60.71

Step-by-step explanation:

Given that:

Consumption of poultry per capita is modeled by:

y=-.2125t^2 + 2.615t+56.33 ; t = 0 corresponds to 1990

Per capita poultry consumption in 1992;

1992 ; t = 2

y=-.2125t^2 + 2.615t+56.33

Put t = 2 in the equation

y=-.2125(2)^2 + 2.615(2) +56.33

y = -.2125(4) + 2.615(2) + 56.33

y = - 0.85 + 5.23 + 56.33

y = 60.71

solve the following quadratic equation for all value of c i'm simplest form
5(x-2)^2=20

Answers

Answer:

x=-2 and x=0

Step-by-step explanation:

5(x-2)^2 =  20; divide by 5 both sides

(x-2)^2 = 4; take the square root of both sides

(x-2) = ±2, now set it equal to positive 2 and negative 2

x-2 = 2

x=4

AND

x-2 = -2

x=0

Answer:

The values of x is 0 and 4.

Step-by-step explanation:

You have to divide 5 by both sides;

[tex]5 {(x - 2)}^{2} = 20[/tex]

[tex] {(x - 2)}^{2} = 4[/tex]

You have to expand the brackets;

[tex] {x}^{2} - 4x +4 = 4[/tex]

[tex] {x}^{2} - 4 x = 0[/tex]

You have to factorize;

[tex]x(x - 4) = 0[/tex]

Lastly, you have to solve it;

[tex]x = 0[/tex]

[tex]x = 4[/tex]

1. AAS

2. SAS

Step-by-step explanation:

1. From the graph it can be seen that two pairs of angles are congruent. The side that is not between the two sides is also congruent. Thus we can use AAS (two angles and a side that is not between the two angles) postulate.

2. The graph shows that there are two pairs of congruent sides. We can also prove that angle ACB is congruent to angle DCE because the two angles are vertical. So we can use the SAS postulate.

What equation is being represented by this line?

Answers

Answer:

The equation that represented by the line is y = -x + 2

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

m is the slope of the lineb is the y-intercept (value y at x = 0)

The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where  

(x1, y1) and (x2, y2) are two points on the line

From the given figure  

∵ The line passes through points (2, 0) and (0, 2)

∴ x1 = 2 and y1 = 0  

x2 = 0 and y2 = 2  

→ Substitute them in the rule of the slope to find it

∵ m =  [tex]\frac{2-0}{0-2}=\frac{2}{-2}=-1[/tex]

m = -1  

→ Substitute it in the form of the equation above

∵ y = -1(x) + b

∴ y = -x + b  

∵ b is value y at x = 0  

∵ At x = 0, y = 2

b = 2

→ Substitute it in the equation above

∴ y = -x + 2

The equation that represented by the line is y = -x + 2

f(x) = 2x, find the ordered pair when x = 1. O (1,2) 0 (4,1) (2,1) O (1,4)​

Answers

Answer:

The ordered pair is (1, 2) ⇒ A

Step-by-step explanation:

In the function f(x) = y

x is the domain of the functiony is the range of the functionThe domain is all the x-coordinates of the points lie on the graph of the functionThe range is all the y-coordinates of the points lie on the graph of the function

That means any ordered pair (x, y) satisfy the function f(x) = y, lies on the graph of the function

∵ f(x) = 2x

→ That means y = 2x

x = 1

→ Substitute the value of x in the function above

∴ f(1) = 2(1)

f(1) = 2

→ That means at x = 1, y = 2

The ordered pair is (1, 2)

Simone paid $12 for an initial year's subscription to a magazine. The renewal rate is $7 per year. This situation can be represented by the equation y = 7x + 12, where x represents the number of years the subscription is renewed and y represents the total cost, in dollars.

Answers

Answer:

Step-by-step explanation:

Step one:

Simone paid $12 initial subscription

The rate renewable = $7 per year

let the number of years be x

and the total amount be y

the linear function/expression for the total amount is represented using the equation of line

i.e y=mx+c

where

     m= gradient = $7

     x= independent variable

     c= constant, $12

this is also given as

y=7x+12

Step two:

let's assume the plan is for 3 years, that is x=3

then

y=7(3)+12

y=21+12

y=33

$33

For any number of years, just put x=the number of years and solve

x(30;0)
y(0;50)
substitue 0 for y and solve for x
substitute 0 in for x and solve for y

Answer:

(30, 0) and (0, 50)

Step-by-step explanation:

( 0 , y ) are coordinates of y-intercept.

( x , 0 ) are coordinates of x-intercept.

25x + 15y = 750

25(0) + 15y = 750 ⇒ y = 50

( 0 , 50 ) are coordinates of y-intercept.

25x + 15(0) = 750 ⇒ x = 30

( 30 , 0 ) are coordinates of x-intercept.

Answer:

D. slope 3 y-intercept 4.

Step-by-step explanation:

The graph crosses the y-coordinate at positive 4. So we know that the y-intercept is 4, which means it cannot be A. slope 1/3. y-intercept -4, or C. slope 3 y-intercept -4.

The slope is 3, you can tell because the line ascends 3 y values for every x value gained.

This means that the answer is D. slope 3 y-intercept 4.
