Answer:

V = (x)(10-2x)² . . . . factored form

V = 4x³ -40x² +100x . . . . standard form

Step-by-step explanation:

A square with corners cut out has no volume. It is a plane figure.

We presume you are interested in the volume of the open-top box obtained by folding up each "ear" of the cut figure. The length of each side of its square bottom is 10-2x. The depth of the box is x. So, the volume is ...

V = LWH = (10-2x)(10-2x)(x)

V = x(10 -2x)²

_____

The graph shows the volume is a maximum when x = 1 2/3 cm.

Translate the shape by the vector { -1 }
5

Answers

Answer:

Step-by-step explanation:

Coordinates of the given rectangle are,

A → (3, 3)

B → (6, 3)

C → (6, 1)

D → (3, 1)

Translation of the given rectangle by the vector [tex]\binom{-1}{5}[/tex] means, shifting of rectangle by 1 unit to the left and 5 units up.

So the rule which defines the translation of the vertices by the given vector is,

(x, y) → (x - 1, y + 5)

By this rule, after translation vertices of image rectangle will be,

A(3, 3) → A'(2, 8)

B(6, 3) → B'(5, 8)

C(6, 1) → C'(5, 6)

D(3, 1) → D'(2, 6)

Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill. If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk?

Answers

Given :

Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill.

To Find :

If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk.

Solution :

Time taken to walk one mile uphill is :

[tex]t_1 = \dfrac{1}{3}\ hours[/tex]

Time taken to walk two mile on flat land( one on going and one or returning ) is :

[tex]t_2 = \dfrac{2}{4}\ hours\\\\ t_2 = \dfrac{1}{2}\ hours[/tex]

Time taken to walk one mile downhill is :

[tex]t_3 = \dfrac{1}{5}\ hours[/tex]

Total time taken :

[tex]T = t_1 + t_2 + t_3 \\\\T = \dfrac{1}{3} + \dfrac{1}{2}+\dfrac{1}{5}\\\\T = \dfrac{10 + 15 + 6}{30} \\\\T = \dfrac{31}{30}\ hours = \dfrac{31}{30}\times 60 \ minutes\\\\T = 62\ minutes[/tex]

Therefore, time taken un 62 minutes.

To catch a ball, a professional baseball player leaps into the air with an initial velocity of
14 feet per second. Write a model for the height of the player above the ground after t seconds. After how many seconds does the player land on the ground? What would be the domain of this function?

Answers

Answer:

The answer is below

Step-by-step explanation:

a) The baseball player leaps into the air with an initial velocity of 14 feet per second. This means that the player leaps from the ground, the initial height is therefore zero.

The height (y) is given by the formula:

y(t) = ut - (1/2)gt² + initial heigth

u = initial velocity = 14 ft/s, t = time taken, g = acceleration due to gravity = 32 ft/s². Substituting:

y(t) = 14t - (1/2) * 32 *t² + 0

y(t) = 14t - 16t²

b) when the player is on the ground, the height = 0. hence:

0 = 14t - 16t²

16t² - 14t = 0

t(16t - 14) = 0

t = 0 or 16t - 14 = 0

t = 0 or 16t = 14

t =0 or t = 0.875

Hence t = 0.875 seconds

c) The domain is the set of possible values for the time. Hence:

Domain = (0, 0.875] = 0 < t ≤ 0.875

2. Abbey rode her bike for 1 3/4 hours on Saturday and 1 5/8 hours on Sunday. What is the total amount of time she rode her bike on these two days ?

Answers

Answer:

1. Andrew grew 4 5/12 inches in 2 years

2. Abbey rode her bike for 3 3/8 hours in 2 days.

Step-by-step explanation:

When adding fractions you must have a common denominator for both of them.

First make the mixed fraction, improper fractions.

1 3/4 = 7/4

2 2/3 = 8/3

7/4 x 3/3 = 21/12

8/3 x 4/4 = 32/12

21 + 32 = 53

53/12 = 4 5/12

1 3/4 = 7/4

1 5/8 = 13/8

7/4 x 4/4 = 28/16

13/8 x 2/2 = 26/16

26 + 28 = 54

54/16 = 3 3/8

Answer:

[tex]m\angle BYP=42^\circ[/tex]

Step-by-step explanation:

Lines and angles

The figure shows three lines forming two angles BYP and PYH whose measures add up to 90° because it's marked as a right angle.

[tex]m\angle BYP+m\angle PYH=90^\circ[/tex]

We are given the acute angles as a function of m. thus:

5m + 98 + 2m + 48 = 90

Simplifying:

5m + 146 = 90

5m = -56

m = -56/5 = -11.2

m = -11.2°

To find the measure of angle BYP, substitute m in

5m + 98 = 5*(-11.2) + 98 = 42°

[tex]m\angle BYP=42^\circ[/tex]

There are many men who feel a kind of twister pride in cynicism, there are many who confine themselves to criticism of the way others dowhat they themselves dare not even attempt.

A cynical habit of thought and speech, a readiness to criticise work which the critic himself never tries toperform, an Intellectual aloofness which will not accept contact with life's realities - all these are marks, not as the possessor would fain to think,of superiority but of weakness.
