Answer:

1(left) goes with 1

2(left)  goes with 3

3(left) goes with 2

4(left) goes with 4

Step-by-step explanation:

2(5+6) = 22


3(5+3) = 24


2(4+5) = 18


2(3+2) = 10  

10 + 12 = 22  

8+ 10 = 18


15 + 9 = 24


6 + 4 = 10

1(left) goes with 1

2(left)  goes with 3

3(left) goes with 2

4(left) goes with 4

Answer:

10 + 12 = 2(5+6) . 10+12=22, 5+6 = 11, 11×2 =22 or 2× (5+6) = 22.

8+10= 2(4+5) , 8+10=18. 2 × (4+5) = 18, 4+5=9, 9×2=18.

15+9= 3(5+3) , 15+9=24, 5+3=8, 8×3 =24 or 3× (5+3)

6+4= 2(3+2), 6+4=10, 3+2 = 5 , 5×2 =10

Write an equation for a polynomial with all the following features: The Degree is 5. The graph of the Polynomial crosses the ver
dimulka [17.4K]

Answer: f(x) = a*x^5 + b*x^3 + c*x^2 + 12.

Step-by-step explanation:

The degree is 5, so we will have a term like:

a*x^5

it crosses the vertical axis at y = 12, then we will have a constant term equal to 12.

The polynomial has 4 terms, and we already defined two, so we can invent two more, such that the exponent must be between 1 and 4

This polynomial can be something like:

f(x) = a*x^5 + b*x^3 + c*x^2 + 12.

where a, b and c are real numbers.

Has 4 terms, f(0) = 12, then it intersects the y-axis at y = 12, and the maximum exponent is 5, then the degree of f(x) is 5.

Joe's grandma lives 36 blocks up the street from Joe. On Saturday, Joe
Kay [80]

Answer:

108 blocks.

Step-by-step explanation:

Joe's grandmother lives 36 blocks away from Joe.

Joe rode two thirds of the way to the house is 2/3 * 36= 24 blocks.

Then he rode back to his house (1 - 2/3) * 36= 12 blocks.

Then Joe rode back to grandma's house= 36 blocks.

Then he rode straight home= 36 blocks.

Total number of blocks he rode is 24+12+36+36= 108 blocks.

Brianna has x nickels and y pennies. She has no less than 20 coins worth no more
Bond [772]

Answer:

y \ge 20 - x

y \le 80 -5x

(x,y) = (15,5)

Step-by-step explanation:

Given

Nickels = x

Pennies = y

Amount = \$0.80 maximum

Coins = 20 minimum

Required

Solve graphically

First, we need to determine the inequalities of the system.

For number of coins, we have:

x\ +\ y\ge 20 because the number of coins is not less than 20

For the worth of coins, we have:

0.05x\ +\ 0.01y\ \le0.80 because the worth of coins is not more than 0.80

So, we have the following equations:

x\ +\ y\ge 20

0.05x\ +\ 0.01y\ \le0.80

Make y the subject in both cases:

y \ge 20 - x

0.01y \le 0.80 - 0.05x

Divide through by 0.01

\frac{0.01y}{0.01} \le \frac{0.80}{0.01} -\frac{ 0.05x}{0.01}

y \le \frac{0.80}{0.01} -\frac{ 0.05x}{0.01}

y \le 80 -5x

The resulting inequalities are:

y \ge 20 - x

y \le 80 -5x

The two inequalities are plotted on the graph as shown in the attachment.

y \ge 20 - x --- Blue

y \ge 80 -5x --- Green

Point A on the attachment are possible solutions

At A:

(x,y) = (15,5)

Find the size of the angle using Sohcahtoa or Pythagoras.
lisov135 [29]

Answer:

x ≈ 38.7°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinx = \frac{opposite}{hypotenuse} = \frac{5}{8} , then

x = sin^{-1} (\frac{5}{8} ) ≈ 38.7° ( to 1 dec. place )
