Find the product. 5(4v + 1)

Answer:

B and D

Step-by-step explanation:

2:4 when divided by 2 gets you 1:2

and 2:4 multiplied by 2.5 gets you 5:10

Answer:

B and D

Step-by-step explanation:

So basically we have to find the unit rate of 2:4.

(remember to find the unit rate we have to simplfy the ratio until one of the quantities is 1)

2:4 (divide by 2 on each side)

1:2 (B)

now we can use this unit rate of 1:2 to find out other equal ratios

1:2 (multiply 5 on both sides)

5:10 (D)

Answer:

a^3 + b^3

Step-by-step explanation:

(a + b)(a^2-ab+b^2)

a(a^2 -ab +b^2) +b(a^2-ab+b^2)

a^3 - a^2b +ab^2 + ba^2 -ab^2 +b^3

a^3 -a^2b +a^2b ab^2-ab^2 + b^3

The final answer will then be:

a^3 + b^3

Hope this helps! Have a great one! And I give out the best of luck for whatever quiz this is on!

Answer:

a^3 - b^3

Step-by-step explanation:

a^3+a^2b+ab^2 -a^2b -ab^2 -b^3

a^3 - b^3

Answer:

442.96875 ft.

Step-by-step explanation:

Original Height (h) : 150 ft

Bounce 1 (h₁) : h/2 = 150/2 = 75 ft

Bounce 2 (h₂) : h₁/2 = 75/2 = 37.5 ft

Bounce 3 (h₃) : h₂/2 = 37.5/2 = 18.75 ft

Bounce 4 (h₄) : h₃/2 = 18.75/2 = 9.375 ft

Bounce 5 (h₅) : h₄/2 = 9.375/2 = 4.6875 ft

Bounce 6 (h₆) : h₅/2 = 4.6875/2 = 2.34375 ft

Finding the sum of bounces 1 - 5 :

Distance traveled :

Answer:

442.96875 ft

Step-by-step explanation:

We can model the height of each bounce as a geometric series.

General form of a geometric sequence: [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

If we let n be the number of bounces, then the initial term has to be:

[tex]a_1=\dfrac12(150)=75[/tex]

since this is the height of the ball after the first bounce.

The common ratio r has already been given to us, as we have been told that the height of the bounce halves after each bounce.

[tex]\implies r=\dfrac12=0.5[/tex]

Therefore, the geometric series to model the peak height of each bounce is:

[tex]a_n=75(0.5)^{n-1}[/tex]

(where [tex]a_n[/tex] is the height and n is the number of bounces)

Therefore, to calculate the total number of feet the ball travels until it reaches the peak height of the 6th bounce:

Total = 150 + (2 × sum of 1, 2, 3, 4 & 5th bounces) + 6th bounce

To find the sum, use the geometric sum formula:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

Therefore, the sum of the bounces 1 through 5 is:

[tex]\implies S_5=\dfrac{75(1-0.5^5)}{1-0.5}=145.3125[/tex]

Height of the 6th bounce:

[tex]\implies a_6=75(0.5)^{6-1}=2.34375[/tex]

[tex]\begin{aligned}\textsf{Total distance} & =150+2\left(\dfrac{75(1-0.5^5)}{1-0.5}\right)+75(0.5)^{6-1}\\ & = 150 + 2(145.3125)+2.34375\\ & = 150 + 290.625+2.34375\\ & =442.96875\: \sf ft \end{aligned}[/tex]

Answer:

72 in²

Step-by-step explanation:

since the trap is open left and right, we don't include these side areas.

so, all we have for the surface area are

the top rectangle (2.5 in × 12 in),

the bottom rectangle (2 in × 12 in)

the back rectangle (1.5 in × 12 in)

for the total surface area we need to to add all 3 areas up.

in our case we get

2.5 × 12 = 30 in²

2 × 12 = 24 in²

1.5 × 12 = 18 in²

total is then

30 + 24 + 18 = 72 in²

The two angles sum to equal 180 degrees.

4x + 8x = 180

12x = 180

X = 180/12

X = 15

Answer:

Soln:4x°+8x°=180°

12x°=180°

or,x°=180°/12

or,x°=15

4x°=4×15°=60°

8x°=8×15°=120

Based on the number of times Johnny performs the experiment, the order from the largest difference in relative frequency and actual prob. to the smallest is:

The difference between absolute probability and relative frequency will be larger if the number of experiments performed is smaller.

This is why the largest difference was seen when Johnny performed the experiment 20 times and the smallest difference was seen when the experiment was done 75 times.

Answer: D. Trapezoid

Step-by-step explanation:

From the question, it tells us that each angle was congruent to its opposite angle, since in a rectangle all angles are 90 degrees, rectangles won’t be correct. Parallelograms is self explanatory. Rhombuses have 2 pairs of same angles, which only leads to a trapezoid with 2 different bases, leading to different angles in it’s opposite corner.

Answer:

(a) 5 units up

(b) 3 units right

(c) 7 units left

Step-by-step explanation:

Parent equation:  [tex]y=x^2[/tex]

Transformed equation:  [tex]y = (x - h)^2+ k[/tex]

h translates the parabola horizontally

If h > 0 then the translation is h units to the right.

If h < 0 then the translation is h units to the left.

If h = 0 then there is no horizontal translation.

k translates the parabola vertically

If k > 0 then the translation is k units up.

If k < 0 then the translation is k units down.

If k = 0 then there is no vertical translation.

Part (a)

Given equation:  [tex]y=x^2+5[/tex]

Rewriting in transformed equation form:  [tex]y=(x-0)^2+5[/tex]

Therefore, the parabola is translated 5 units up.

Part (b)

Given equation:  [tex]y=(x-3)^2[/tex]

Rewriting in transformed equation form:  [tex]y=(x-3)^2+0[/tex]

Therefore, the parabola is translated 3 units right.

Part (c)

Given equation:  [tex]y=(x+7)^2[/tex]

Rewriting in transformed equation form:  [tex]y=(x+7)^2+0[/tex]

Therefore, the parabola is translated 7 units left.

Part (d)

Given equation:  unreadable
