Is 2j+8k - 4k and 8 (1j+ik) equivalent

9514 1404 393

Answer:

Step-by-step explanation:

A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).

Here, we have ...

  h = -16t^2 +44t +5

  t = -44/(2(-16)) = 11/8 = 1.375

It takes 1.375 seconds for the ball to reach its maximum height.

The height at that time is ...

  h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25

The maximum height is 35.25 feet.

Answer:

7

Step-by-step explanation:

Tyger = x

Dinos = x + 9

Total = 23

x + x+9 = 23

2x + 9 = 23

2x = 23 - 9

2x = 14

x = 14/2 = 7

I hope im right!!

Answer:

x = 3, y = 30.4

Step-by-step explanation:

From the given diagram;

8x - 3 = 6x+3 (alternate exterior angle are equal)

Collect like terms

8x - 6x = 3 + 3

2x = 6

x = 6/2

x = 3

Also;

8x - 31 + 5y + 35 = 180 (sum of angle on a straight line is 180)

8(3) - 31 + 5y + 35 = 180

5y + 24 - 31 + 35  = 180

5y + 28 = 180

5Y = 180 - 28

5Y = 152

y = 152/5

y = 30.4

Hence x = 3, y = 30.4

We will calculate the total amount for each of the credit card and then arrange them in descending order according to their interest after 36 months (3 years)

Interest on Credit card 1 =

                                       = $2233

Interest on credit card 2 =

                                       = $778

Interest on credit card 3 =

                                       = $1656

Interest on credit card 4 =

                                       = 2250

Hence the correct order to pay off all the credit card balances is

#4, #1, #3, #2

Her total monthly credit card payment will be $561.05.

Given that Michelle has four credit cards with the balances and interest rates listed below, if Michelle wanted to pay off all four credit cards in 36 months, to determine what would her total monthly credit card payment be, calculate the total amount of each card of credit including interest, add all the amounts, and then divide the result by 36:

Therefore, her total monthly credit card payment will be $561.05.

Answer: $5

Step-by-step explanation:

We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.

Therefore, let the price of the socks be represented as x.

70% of x = 14

70/100 × x = 14

0.7 × x = 14

0.7x = 14

x = 14 / 0.7

x = 20

Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:

= $20 / 4

= $5

Answer:

y=36degrees

Step-by-step explanation:

74+2y+34=180

2y+108=180

2y+108-108=180-108

2y=72

72/2

y=36degrees

Answer:

Step-by-step explanation:

Because these are supplementary angles they must have a sum of 180 degrees.

74+2y+34=180

2y+108=180

2y=72

y=36 degrees

Answer:

502.85 feet

Step-by-step explanation:

Given that,

The radius of a Ferris wheel, r = 16 feet

We need to find how far will you travel if you take a ride that goes around 5 times.

Distance = 5×2πr

So,

= 10πr

[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]

So, the required distance is 502.85 feet.

Answer:

D. y + 7 = -3(x - 5)

Step-by-step explanation:

Point-slope form: y - y₁ = m(x - x₁)

⇒ y - (-7) = -3(x - 5)

⇒ y + 7 = -3(x - 5)

Answer:

B. y + 7 = 3(x - 5).

Step-by-step explanation:

y -y1 = m(x - x1)

y - (-7) = 3(x - 5)

y + 7 = 3(x - 5).

Answer:

sinA = 12/13, cosA = 5/13, tanA = 12/5

sinB = 5/13, cosB = 5/13, tanB = 5/12

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

Sin(A) = 12/13

Sin(B) = 5/13

Cos(A) = 5/13

Cos(B) = 12/13

Tan(A) = 12/5

Tan(B) = 5/12
