Step-by-step explanation:

Projectile B begins its descent 1 seconds before Projectile A does.

In Mathematics and Geometry, the y-intercept of any graph or table such as a quadratic equation or function, generally occurs at the point where the value of "x" is equal to zero (x = 0).

By critically observing the table shown in the image attached above, we can reasonably infer and logically deduce the following y-intercept of Projectile A:

y-intercept = (0, 44).

Maximum height = (4, 300).

When t = 0, the y-intercept of Projectile B can be calculated as follows;

h(t) = -16t² + 96t

h(0) = -16(0)² + 96(0)

h(0) = 0.

For the maximum height, we have:

h(t) = -16t² + 96t

h'(t) = -32t + 96

32t = 96

t = 96/32

t = 3

Difference in time = 4 - 3

Difference in time = 1 seconds.

Answer:

  see the attachment for a table

Step-by-step explanation:

You asked "how do you do this one?" My answer to that is, "use a graphing calculator or spreadsheet."

The given formula can be evaluated repeatedly for different values of t quite easily by a graphing calculator or spreadsheet. Enter the formula and have it be applied to the given t-values. A spreadsheet provide cell formatting so that rounding can be to whatever precision you desire.

The values in the table attached will need to be rounded to one decimal place "by hand."

Answer:

$2,149.63

Step-by-step explanation:

She makes an initial payment of $1,451 and pays one-third of the previous month's payment each of the following months.

1/3 × $1,451 = $483.67 (second month)

$483.67 + $1,451 = $1,934.67

1/3 × $483.67 = $161.22 (third month)

$161.22 + $1,934.67 = $2,095.89

1/3 × $161.22 = $53.74 (fourth month)

$53.74 + $2,095.89 = $2,149.63

$2,149.63 of the invoice will be paid after the fourth month.

Hope that helps.

Approximately $2,149.63 of the invoice will be paid after the fourth month.

Option C is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The patient makes an initial payment of $1,451 in the first month.

In each subsequent month, the patient pays one-third of the previous month's payment.

Let P be the amount paid in the first month, and let M be the amount paid in each subsequent month.

Then we have:

P = $1,451

M = (1/3)P

So the amounts paid in each month are:

Month 1: $1,451

Month 2: (1/3)P = (1/3)($1,451) = $483.67

Month 3: (1/3)M = (1/3)($483.67) = $161.22

Month 4: (1/3)M = (1/3)($161.22) = $53.74

The total amount paid after four months.

= $1,451 + $483.67 + $161.22 + $53.74

= $2,149.63

Therefore,

Approximately $2,149.63 of the invoice will be paid after the fourth month.

Step-by-step explanation:

1). m∠AEC = m∠AEB + m∠BEC

                  = 21° + 37°

                  = 58°

2). m∠BED = m∠BEC + m∠CED

                   = 37° + 44°

                   = 81°

3). m∠IKF = m∠IKH + m∠HKG + m∠GKF

                = m∠IKH + m∠HKG + m∠IKH [Since, ∠IKH ≅ ∠GKF]

                = 2∠IKH + m∠HKG

         103° = 2∠IKH + 41°

   2(∠IKH) = 103 - 41

 m(∠IKH) = 31°

4). m∠AED = m∠AEB + m∠BEC + m∠CED

                  = 21° + 37° + 44°

                  = 102°

5). m∠JKG = 108°

    m∠JKG = m∠JKI + m∠IKH + m∠HKG

    108° = m∠JKI + 31° + 41°

    m∠JKI = 108° - 72°

    m∠JKI = 36°

6). m∠HKF = m∠GKF + m∠HKG

                  = m∠IKH + m∠HKG [Since, m∠GKF = m∠IKH]

                  = 31° + 41°

                  = 72°

7). m∠NQO = m∠MQN = 64°

8). m∠JKF = m∠JKI + m∠IKF

                 = 36° + 103°

                  = 139°

8). m∠MQO = 2(m∠NQO)

                    = 2(64)°

                    = 128°

9). m∠LQO = 156°

    m∠LQM = m∠LQO - m∠MQO

                    = 156° - 128°

                    = 28°

10. m∠NQP = m∠NQO + m∠OQP

                   = 64° + m∠LQM [Since ∠OQP ≅ ∠LQM]

                   = 64° + 28°

                   = 92°

Answer:

x = 3

Step-by-step explanation:

Simplifying

(2x + -6) + 4(x + -3) = 0

Reorder the terms:

(-6 + 2x) + 4(x + -3) = 0

Remove parenthesis around (-6 + 2x)

-6 + 2x + 4(x + -3) = 0

Reorder the terms:

-6 + 2x + 4(-3 + x) = 0

-6 + 2x + (-3 * 4 + x * 4) = 0

-6 + 2x + (-12 + 4x) = 0

Reorder the terms:

-6 + -12 + 2x + 4x = 0

Combine like terms: -6 + -12 = -18

-18 + 2x + 4x = 0

Combine like terms: 2x + 4x = 6x

-18 + 6x = 0

Solving

-18 + 6x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + 6x = 0 + 18

Combine like terms: -18 + 18 = 0

0 + 6x = 0 + 18

6x = 0 + 18

Combine like terms: 0 + 18 = 18

6x = 18

Divide each side by '6'.

x = 3

Simplifying

x = 3

Answer:

the answer is 6x-18

Answer:Look at the step by step it’s correct

Step-by-step explanation:

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. The correct option is D.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

Suppose that the given quadratic equation is

 ax² + bx + c = 0

Then its roots are given as:

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

For the given equation, the value of a, b, and c is 1, -10, and 125, respectively. The roots of the given quadratic equation are,

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{-(-10) \pm \sqrt{(-10)^2 - 4(1)(125)}}{2(1)}\\\\x = \dfrac{10 \pm \sqrt{100 - 500}}{2}\\\\x = \dfrac{10 \pm 20i}{2}\\\\[/tex]

x = 5 ± 10i
