Find the side length x. Round answer to the nearest hundredth.

Given:

The function is:

[tex]f(x)=4x^2-25x-21[/tex]

To find:

The domain of the given function.

Solution:

Domain is the set of input values.

We have,

[tex]f(x)=4x^2-25x-21[/tex]

It is a quadratic polynomial.

We know that a quadratic polynomial is defined for all real values of x. So, the given function is defined for all real values of x and the domain of the given function is:

Domain = Set of all real number

Domain = (-∞,∞)

Therefore, the correct option is B.

Answer:

36.5 feet long.

Step-by-step explanation:

38-1.5 is equal to 36.5, you subtract to find the other number, therefor one piece is 1.5 feet long and the other is 36.5 feet long.

Answer:

36.5 feet long

Step-by-step explanation:

38 - 1.5

= 36.5

Answer:

there are 534 inches pieces of remaining wood left.

Step-by-step explanation:

If we convert 15 yards into inches. it would be 540 so you just have to subtract 540 - 6 and that will give you 534.

Answer:

u=13[tex]\sqrt{2}[/tex] and v=13[tex]\sqrt{2}[/tex]/2

Step-by-step explanation:

Answer and Step-by-step explanation:

These two terms (pronounced as Sine and Cosine) are used to solve for the sides and angles of a triangle in Trigonometry.

They are functions revealing the shape of a right triangle.

Sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.

Cosine is also a trigonometric function of an angle. The cosine of an angle is the relation of the length of the side that is adjacent that angle, to the length of the longest side of the triangle.

Answer:30

Step-by-step explanation:

Answer:

5/6

Step-by-step explanation:

what you do first is find the common denominator

so that would be:

3/6 + 2/6

then you would add them

so that would be:

3/6 + 2/6 = 5/6

and 5/6 is your answer

Answer:

The volume of the pyramid is 867 inch^3

Step-by-step explanation:

Here in this question, we are interested in calculating the volume of a square based pyramid.

Mathematically, we can use the formula below to calculate the volume V of a square based pyramid.

V = a^2h/3

where a represents the length of the side of the square and h is the height of the pyramid

From the question, the length of the side of the square is 17 in while the height is 9 in

Plugging these values, we have ;

V = (17^2 * 9)/3 = 17^2 * 3 = 867 cubic inch

Answer:

x = 7

Step-by-step explanation:

Exterior angle thm:

4x + 12 + 7x + 12 = 101

11x + 24 = 101

11x = 101 - 24

11x = 77

x = 7

Answer:

nose es algo q no se puede saber

In other words, it's 2 feet, 3 inches

=================================================

Work Shown:

Convert the 4'1" to purely inches only

4'1" = 4 ft, 1 inch

4'1" = 4 ft + 1 inch

4'1" = 48 inches + 1 inch

4'1" = 49 inches

Note how 4 ft = 4*12 = 48 inches

-------------------

Through similar steps, you should find that 1'10", aka 1 ft 10 inches, is equivalent to 22 inches

Subtracting the two quantities gets us

(4' 1") - (1' 10") = (49 inches) - (22 inches) = 27 inches

Now convert that to the format "feet,inches".

27 in = 24 in + 3 in

27 in = (24/12 ft) + 3 in

27 in = 2 ft + 3 in

27 in = 2 ft, 3 in

27 in = 2' 3"

Answer:

the answer will be 18 ohkay but they will eill have more dimes than quarters

Answer:

Please the answer from the other user is completely wrong, the real answer is 7 quarters and 13 dimes

Step-by-step explanation:

0.1 (x+6) + 0.25x = 3.05

0.35x = 2.45

x = 7

therefore,

7 quarters

x+6 dimes = 13 dimes

Answer:

C. 10 = 2.5 + 0.5x

Step-by-step explanation:

A. 0.5x + 2.5 = 10

B. 0.5 – 2.5 = 10x

C. 10 = 2.5 + 0.5x

D. 2.5x + 0.5 = 10

E. 2.5x – 0.5 = 10

Total distance Hector covers = 10 km

Distance he has covered = 2.5 km

Distance he covers per week = 0.5 km

Let

x = number of weeks

The equation is given by

2.5 + 0.5x = 10

It can also be written as:

10 = 2.5 + 0.5x

10 - 2.5 = 0.5x

7.5 = 0.5x

x = 7.5/0.5

x = 15 weeks

Answer:

A and C

0.5x + 2.5 = 10

10 = 2.5 + 0.5x

Answer:

The largest value of x will be [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

[tex]3x-7<-2[/tex]

[tex]3\frac{5}{3}-7<-2[/tex]    

[tex]\frac{15}{3} -7<-2[/tex]      Always multiply whole number then numerator

[tex]5-7<-2[/tex]       Statement is false so that means x has to be less than 5/3

So the largest value of x will be [tex]\frac{4}{3}[/tex]

Answer:

Step-by-step explanation:

using pythagoras theorem

h^2=p^2+b^2

3^2=q^2+2^2

9=q^2+4

9-4=q^2

5=q^2

[tex]\sqrt{5}[/tex] =q

Answer:

Part A: x + y = 36, 3x + y = 54

Part B: (9, 27), I used subtraction to solve the system, because it eliminated the "y" value, so it would be easiest to solve.

Step-by-step explanation:

Amount of Bean Packets: x

Amount of Frogs: y

We are given that:

x + y = 36

3x + y = 54

This is the answer to answer A.

To solve, use subtraction. Subtract:

3x + y - (x + y) = 54 - 36

3x - x + y - y = 18

2x = 18

x = 9

Substituting x = 9 into x + y = 36, we find that y = 27

In (x, y) form, substitute x = 9 and y = 27 to get (9, 27)

I used subtraction to solve the system, because it eliminated the "y" value, so it would be easiest to solve.
