The value of the function h(2) for h(t) = -16t2 + 32t + 5 is h(2) = 5

From the question, the function definition is given as

h(t) = -16t2 + 32t + 5

First, we express the exponent in the function properly

This is represented as

h(t) = -16t² + 32t + 5

The function value to calculate is given as

h(2)

This means that we calculate h(t) when t = 2

So, we have

h(2) = -16(2)² + 32(2) + 5

Evaluate the exponents

h(2) = -16(4) + 32(2) + 5

So, we have

h(2) = 5

Hence, the function value is 5

Answer:

-0.7 < -0.4

0.5 > -0.6

-0.8 < -0.7

0.6 > 0.4

Explanation:

The symbol < means less than and the symbol > means greater than.

On the other hand, if we identify each number on a number line, we get:

Therefore, the true statements are:

-0.7 < -0.4

0.5 > -0.6

-0.8 < -0.7

0.6 > 0.4

Because, for example, -0.7 is on the left of -0.4 which means that -0.7 is less than -0.4.

0.5 in on the right of -0.6 which means that 0.5 is greater than -0.6.

The equation relating to A to B is A = 45 + b and the amount is $66.

An equation is used to show the relationship between the variables that are illustrated.

In this case, Kala earns 45 dollars each week working part-time at a bookstore and she earns one additional dollar for each book that she sells.

Let the books be represented as b. The equation will be:.

A = 45 + 1b

A = 45 + b

where A = amount earned.

The amount earned when 21 books are sold will be:

A = 45 + b

A = 45 + 21

A = 66

The amount is $66.

It took David 1 [tex]\frac{3}{4}[/tex] hours more to reach her aunt's home due to labor day traffic.

The unitary method is a method in which you find the value of a single unit and then the value of a required number of units.

Given is Davin who needs 1 3/4 hours to get to his aunt's house. However, due to the labor day traffic this year it took him 3 1/5 years.

We have to find the difference between the time span Davin took to reach his aunt's house.

Time taken by Davin without the labor day traffic = T[N] = 1 3/4 = 7/4 hours

Time taken by Davin with the labor day traffic = T[L] = 3 1/5 = 16/5 hours

Difference in time spans = T[D] = T[L] - T[N]

T[D] = 16/5 - 7/4

T[D] = 3.2 - 1.75

T[D] = 1.45 = 1 + 0.45

T[D] = 1 [tex]\frac{3}{4}[/tex] hours  

Davin took 1 [tex]\frac{3}{4}[/tex] hours more.

The value of the unknown angle x is 22 degrees.

SV is a parallel to RU.

RV is a transversal line that cut across the parallel lines SV and RU.

Therefore,

x = ∠V(alternate angles)

Alternate angles are congruent.

Hence,

∠V + 44 + 5x + 4 = 180 (sum of angles in a triangle)

x + 44 + 5x + 4 = 180

x + 5x + 48  = 180

6x + 48 = 180

6x = 180 - 48

6x = 132

The measure of the value of ∠j is 10°.

What are a few properties of a triangle considering its angles?
A triangle's outer angle is the sum of its internal angles' two opposite sides.
The sum of two linear angles is supplementary.

Given, the three angles of the triangle are measured as (5x - 3)°,
(4x - 2)° and j°.
Also, the exterior angle of the triangle is (10x - 20)°.
Following the literature established above, considering that a triangle's outer angle is the product of its internal angles' two opposite sides, we have: (5x - 3) + (4x - 2) = 10x - 20 ⇒ 9x - 5 = 10x - 20 ⇒ 10x - 9x = 20 - 5
⇒ x = 15 --(i)
Again, since the sum of two linear angles is supplementary, we have using (i):
j + (10x - 20) = 180 ⇒ j + 150 - 20 = 180 ⇒ j = 10°
Therefore, the measure of the value of ∠j is 10°.

From the question, we are asked to find which is great between 12.5 or |-13|

recall:

|-13|

The absolute value is the distance between a number and zero. The distance between -13 and 0 is 13.

The absolute symbol makes any number positive.

So, |-13| is the greater because |-13| = 13.

So, between 12.5 and |-13|, |-13| is greater since it is same as 13.

What is Graph?

The graph of a function f is the set of ordered pairs where "displaystyle f(x)=y" exists. In the common scenario when x and f(x) are real integers, these pairings represent Cartesian coordinates of points in two-dimensional space and hence constitute a subset of this plane.

M(x) = |x + 1|

|x + 1| = M(x)

x + 1 = M(x)

x + 1 = -M(x)

Adding (-x) both side

x + 1 + (- x) = M(x) + (- x)

x + 1 + (- x) = -M(x) + (- x)

x + 1 - x = M(x) - x

x + 1 - x = -M(x) - x

1 = M(x) - x

1  = -M(x) - x

M(x) - x = 1

-M(x) - x  = 1

x(M-1)  = 1

x(-M-1)  = 1

Dividing both side with (M - 1) and (-M - 1)

x(M-1)/(M - 1)   = 1/(M - 1)

x(-M-1)/(-M - 1)  = 1 /(-M - 1)

x = 1/(M - 1)

x = 1/(-M - 1)

Hence, x = 1/M-1 , x = -1/M+1

We can apply the Obtuse Triangle Theorem to check if the the measures of the sides appropiately represents the measures of the triangle:

Perimeter = 40 cm = 4x + 2x + 2 + x + 3

Adding like terms:

40 = 7x + 5

Subtracting 5 to both sides:

40 - 5 = 7x

Adding like terms:

35 = 7x

Dividing both sides by 7:

So, 2 gallon would be 2/0.0625 = 32 cups

So, the problem in cups is:

32 cups = $23.36

17 cups = $20.06

Definitely 32 cups for 23.36 is better buy

The fraction of oranges eaten by the family is 3/5

Given,

Number of oranges in a bag = 8 oranges

Number of bags sold to a family = 10 bags

Number of members in the family = 6 members

Number oranges ate by each member of the family = 6 oranges

We have to find the fraction of the oranges eaten by the family members;

Here,

8 oranges in 1 bag and 10 bags sold.

So, total number of oranges sold = 8 x 10 = 80 oranges

Each member ate 6 oranges and there are 8 members.

So, total number of oranges eaten by them = 6 x 8 = 48 oranges

Now,

The fraction of oranges eaten by the family = 48/80 = 6/10 = 3/5

That is,

Using the law of cosines, the length of BC in the given quadrilateral is: 8.1 cm.

The law of cosines that can be used to find the length of a side of a triangle with a known included angle and two sides is:

c² = a² + b² - 2 × a × b × Cos C.

Considering right triangle ABD,

BD = a

DC = b

BC = c

Use the Pythagorean theorem to find the length of BD in the quadrilateral as shown in the diagram:

BD = √(7.5² + 5²)

BD = √(7.5² + 5²)

BD = 9.0 cm

Use the law of cosines to find the length of BC:

BC² = BD² + DC² - 2 × BD × DC × Cos <BDC.
