Answer:

1, 4, 0

Step-by-step explanation:

the way you did it was just right, the arrow can only be split 1 time with equal sides. The hexagon can be split 4 times with equal sides. But the lighting strike cannot be split with equal sides symmetry.

Answer:

3

Step-by-step explanation:

if B has 30% more than A then 1.3 multiplied by 10= 13

so B contains 13 cups

13-10 is how many more B has than A

so the answer is 3

Answer:

[tex]x-intercept(s): (1,0),(-2,0)[/tex]

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

Given the function

f(x) = x^3 − x + 4 in the interval [1,2]

We are to find the value of x for which f(x) = 7

Substitute f(x) = 7 into the expression as shown!

f(x) = x^3 − x + 4

7 = x^3 − x + 4

x^3 − x + 4 -7 = 0

x^3 − x - 3= 0

x^3 -x = 3

x(x²-1) = 3

x²-1 = 3 and x = 3

x² = 3+1

x² = 4

x = ±√4

x = ±2

Since x lies within the interval, [1,2] hence the value of x is 2

Answer: [tex]2x^2-7x=72[/tex] , where  x= width of the rectangle ( in inches).

Step-by-step explanation:

Let x= width of the rectangle ( in inches).

Then its length =  2x-7 ( in inches).

Area of rectangle = Length × width

= (2x-7) × (x)

= 2x × x -7 ×x

= 2x²-7x

The area of the rectangle is 72 square inches.

[tex]\Rightarrow\ 2x^2-7x=72[/tex]

Hence, the equation that represents the given situation :

[tex]2x^2-7x=72[/tex]

Answer: 9[tex]\pi[/tex]

Step-by-step explanation:

Sorry the pi sign looks weird. The formula for area of a circle is [tex]a=\pi r^2[/tex], so we have to substitute the radius with 3. The square of 3 is 9, so the answer is 9pi.

Answer:

y = 72°, x = 36°

Step-by-step explanation:

Step 1:

2x + 3x = 180°         Supplementary ∠'s

Step 2:

5x = 180°         Combine Like Terms

Step 3:

x = 180° ÷ 5         Divide

Step 4:

x = 36°      

Step 5:

3x + y = 180°        Supplementary ∠'s

Step 6:

3 ( 36 ) + y = 180°      Input x value

Step 7:

108° + y = 180°       Multiply

Step 8:

y = 180° - 108°         Subtract

Answer:

y = 72°, x = 36°

The steeper the line (graph), the greater the slope and the greater the speed of that particular car.  It is instantly obvious that of the two lines shown, the yellow graph has the greater slope and thus the greater speed.

"The steeper the line, the greater the slope(speed).  "Car 1 is moving at a speed than car 2."
