Given s(t)= -t^3+2t^2+(3/2) be the position of a particle moving along the x-axis at time t. At what time will the instantaneous velocity equal the average velocity over the time interval (0,4)?

Answer:

2 5/7

Step-by-step explanation:

Difference in length = length of blue line - length of red line

[tex]6\frac{2}{7} - 3\frac{4}{7}[/tex]

[tex]3\frac{2-4}{7}[/tex]

Subtract 1 from the whole number and add it to 2, when 1 is added to 2 it becomes (7 + 2) = 9

= 2 5/7

Answer:

B and C

Step-by-step explanation:

First, we need to get the left side equal to zero. Take away 25 from each side to get [tex]4x^2+12x-16 = 0[/tex].

We can use the quadratic equation of [tex]\frac{-b+ -\sqrt{b^2-4ac} }{2a}[/tex] to find the solutions.

Plug them in to get [tex]\frac{-12+-\sqrt{144 -(-256)} }{8}[/tex].

Simplify.

[tex]\frac{-12+-\sqrt{400} }{8}[/tex]

[tex]\frac{-12+-20}{8}[/tex]

[tex]\frac{8}{8}[/tex] or [tex]\frac{-32}{8}[/tex]

1 and -4

x = 1 and -4

Answer:

A. 0.13.

B. 0.15.

Step-by-step explanation:

For the first problem, subtract 0.87 from 1. You get 0.13.

For the second problem, add up 0.3 and 0.55 to get 0.85. Subtract this from 1 to get 0.15.

Hope this helps :)

Answer:

Domain is (-∞, ∞)

Step-by-step explanation:

Given function is [tex]\sqrt[3]{5x+25}[/tex]

Please remember, for any cube root function the domain is all real numbers, because the cube root of any real number is a real number.

So, domain is all real numbers.

We can write it in interval notation as (-∞,∞).

The mathematical expression for "63 less than twice Julie's height"

is 2j - 63

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:

Expression: (Math Operator, Number/Variable, Math Operator)

We have,

63 less than twice Julie's height.

let the height of Julie be j.

Answer:

J. 3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

5m−(m+4)=2

Step 1: Simplify both sides of the equation.

5m−(m+4)=2

5m+−1(m+4)=2(Distribute the Negative Sign)

5m+−1m+(−1)(4)=2

5m+−m+−4=2

(5m+−m)+(−4)=2(Combine Like Terms)

4m+−4=2

4m−4=2

Answer:

y=-2

Step-by-step explanation:

because it's parallel --> a=-2

therefore we have y=-2x+b

Answer:

The statements that complete the proofs are;

First statement

One half the measure of their intercepted arcs

Second statement

mARC CDE = 2·m∠CFE and mARC CFE = 2·m∠CDE

Step-by-step explanation:

The two column proof that ∠CFE and ∠CDE are supplementary is presented as follows;

Statement  [tex]{}[/tex]                                                            Reason

Quadrilateral CDEF is inscribed is circle A  [tex]{}[/tex]       Given

[tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex] = 360°  [tex]{}[/tex]                                 Measure of angle round a circle

∠CFE and ∠CDE are inscribed angles   [tex]{}[/tex]             Given

∠CFE  + ∠CDE = 1/2 × ([tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex])  [tex]{}[/tex]   Inscribed angles are (i) one half the measure of their intercepted arcs

2 × (∠CFE  + ∠CDE) = ([tex]m\widehat{CDE}[/tex] + [tex]m\widehat{CFE}[/tex])

So, (ii) [tex]m\widehat{CDE}[/tex] = 2 × m∠CFE and [tex]m\widehat{CFE}[/tex] = 2 × m∠CDE From the inscribed angle theorem above (See attached drawing)

2·m∠CFE + 2·m∠CDE = 360°  [tex]{}[/tex]    Using substitution property of equality

(2·m∠CFE + 2·m∠CDE)/2 = 360°/2 → m∠CFE + m∠CDE) = 180° [tex]{}[/tex]                Dividing both sides by 2

m∠CFE and m∠CDE) are supplementary  [tex]{}[/tex]  Angles that sum up to 180°

The statements that complete the proofs are;

(i) One half the measure of their intercepted arcs

(ii) mARC CDE = 2·m∠CFE and mARC CFE = 2·m∠CDE

Answer:

1/2 the measure of their intercepted arcs; m arc CDE= 2 ⋅ m∠CFE and arc CFE= 2 ⋅ m∠CDE (or C).
