The square root of 53 lies between which two numbers?

Answers

Answer 1

The square root of 53 lies between 7 and 8.

There are a couple ways to find this. You could...
A. Use a calculator and simply find the square root of 53 (7.280...) OR
B. You could square each number (1^2, 2^2, 3^2...) until you get the closest 2 numbers (one less than and one greater than) to 53 (7^2 = 49) and (8^2 = 64).

Can somone help me with this 1 problem? QRST is a parallelogram. Determine the measure of ∠Q
Q (4x+10) bottom left
R (9x+1) top left
S (5x-3) top right
T bottom left

Answers

(In the picture, QRST looks like a rhombus, so I will assume that it is a rhombus.)

In a rhombus, opposite angles are congruent based on the alternate interior angle theorem. In other words, R and T along with Q and S are both alternate interior angle pairs.
(You can actually test this by printing out a rhombus, cutting out the angles, and matching up the opposite ones.)

We know that Q is equal to 4x + 10, but we need to solve for x. Since Q and S are congruent, we can set them equal to each other:
1) 4x + 10 = 5x - 3
2) 4x + 13 = 5x
3) 5x = 4x + 13
4) x = 13
Now let's plug 13 in for Q:
5) 4(13) + 10 = 52+10 = 62

I got m<Q = 62 degrees. Hope this helps!

In the parallelogram QRST then measure of ∠Q is 62 degrees.

What is Quadrilateral?

A quadrilateral is a four-sided polygon, having four edges and four corners.

Given that QRST is a parallelogram.

We have to find the measure of ∠Q.

Both pairs of opposite sides are parallel, quadrilateral QRST is a parallelogram.

∠Q= ∠S

4x+10=5x-3

We have to find the value of to find ∠Q measure.

10+3=5x-4x

13=x

Now let us plug in the value of x in ∠Q measure.

∠Q = 4x+10

Now plug in x value in ∠Q

∠Q = 4(13)+10

=52+10

=62 degrees

Hence, in the parallelogram QRST then measure of ∠Q is 62 degrees.

What are the amplitude and midline?

Amplitude: 1; midline: y = 1
Amplitude: 0; midline: y = 0
Amplitude: 2; midline: y = 1
Amplitude: 2; midline: y = 0

Answers

Amplituide is and midline is y = 1.

Answer:

Amplitude: 1; midline: y = 1

Step-by-step explanation:

From the graph we can conclude that it is a sine or cosine function. In their standard form, these functions are given by the following equations:

[tex]y(t)=Acos(\omega t +\phi)\\\\or\\\\y(t)=Asin(\omega t+ \phi)[/tex]

Where:

[tex]A=Amplitude=\frac{|A_m_i_n-A_m_a_x|}{2}\\\omega=Angular\hspace{3}frequency\\\phi=Initial \hspace{3}phase[/tex]

And:

[tex]A_m_a_x=Maximum\hspace{3}amplitude\\A_m_i_n=Minimum\hspace{3}amplitude[/tex]

On the other hand, we can define the midline of these kind of functions as the halfway between the maximum and minimum amplitude of the function, Therefore:

[tex]Midline=M_l=\frac{A_m_a_x+A_m_i_n}{2}[/tex]

From the graph you can see that the maximum value of the function(maximum amplitude) is 2 and the minimum value of the function (minimum amplitude) is 0, thus:

[tex]A=\frac{|A_m_i_n-A_m_a_x|}{2} =\frac{|0-2|}{2} =\frac{|-2|}{2} =\frac{2}{2} =1[/tex]

And:

[tex]M_l=\frac{A_m_a_x+A_m_i_n}{2}=\frac{2+0}{2} =\frac{2}{2} =1[/tex]

Answers

We have this equation:

[tex]2x^{\frac{9}{8}} = 111[/tex]

and we need to find the value of x.

First of all, we multiply the whole equation for 1/2, so our goal is to isolate x, therefore:

[tex]x^{\frac{9}{8}}=\frac{111}{2}[/tex]

Next step we must do is to apply logarithms:

[tex]logx^{\frac{9}{8}} = log(\frac{111}{2})[/tex]

Next, we have to apply identities and then to solve the equation:

[tex] \frac{9}{8}logx = log(\frac{111}{2})[/tex]
[tex]logx = \frac{8}{9}log(\frac{111}{2})[/tex]
[tex]logx = 1.5504[/tex]
[tex]10^{logx} = 10^{1.5504}[/tex]

Finally, we have the value of x which was our goal. This is the answer for the question above:

Hello there!

Answer: 1 solution
-------------------------------------------------------------------------------------------------------

Explanation:

To solve this, we must isolate the x.

15x + 11 = 8x

We will subtract 15x from each side to isolate the x.

15x + 11 = 8x
- 15x -15x

11 = -7x

Finally, we must simplify this by dividing each side by -7

11 = -7x

Sina played basketball on a rectangular court that was 74 feet by 42 feet. after the game, she walked across the court diagonally from one corner to the opposite corner. approximately what distance did sina walk in feet?

Answers

Distance walked = 85.088 feet

The distance Sina walked would be equal to the length of the diagonal of rectangle.

As every angle in a rectangle is 90 degree. So, we can apply Pythagoras theorem in right triangle formed by sides,

Base- 74 feet, Altitude- 42 feet and Hypotenuse- Diagonal

Base^2 + Altitude ^ 2 = Hypotenuse ^2

74^2 + 42 ^ 2 = Diagonal ^2

On solving,

Diagonal = 85.088 feet

To calculate the distance Sina walked diagonally across the basketball court, we utilize the Pythagorean theorem using the court's length and width. The calculation gives us a diagonal distance of approximately 85 feet.

To calculate the distance Sina walked across the rectangular basketball court diagonally, we can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Since the court is 74 feet long and 42 feet wide, these dimensions can be considered the two shorter sides of a right triangle, with the diagonal Sina walked being the hypotenuse.

The Pythagorean theorem formula is:

[tex]c^2 = a^2 + b^2[/tex]

Where c is the length of the hypotenuse, and a and b are the lengths of the other two sides. Substituting the known values:

[tex]c^2 = 742 + 422\\c^2 = 5476 + 1764\\c^2 = 7240[/tex]

To find c, we take the square root of 7240:

c ≈ 85.09 feet

Therefore, Sina walked approximately 85 feet diagonally across the basketball court.

Hello!

A sample of Bromine-82 begins at 80 mL. We are given that this value will decrease by half of its current amount every 35 hours. First, we'll determine the number of times that 35 goes into 140. This will reveal the number of times we should divide the sample by 2:

140 ÷ 35 = 4

We have now proven that there are 4 periods of 35 hours in 140 hours. This means that we will divide the sample in half a total of 4 times, as follows:

1. 80 ÷ 2 = 40
2. 40 ÷ 2 = 20
3. 20 ÷ 2 = 10
4. 10 ÷ 2 = 5

We have now proven that an 80 mL sample of Bromine-82 will be reduced to only 5 mL after 140 hours. Therefore, the correct answer is 5 mL.

I hope this helps!

To solve this problem, we have to use the half-life formula, where A represents the remaining amount, P is the initial amount, t is the time that has passed, and h is the substance's half-life:

2,400 principal earning 2%, compounded annually, after 7 years. Find the balance in the account

Answers

A = P (1 + r/n) ^nt
P = 2400
r = .02
n = 1
t = 7

Answer: $2756.86

The balance in the account after 7 years will be approximately $2,747.70.

How did we get the value?

To calculate the balance in the account after 7 years with a principal of $2,400 earning 2% interest compounded annually, you can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the future balance

P = the principal amount ($2,400)

r = the annual interest rate (2% or 0.02 as a decimal)

n = the number of times the interest is compounded per year (annually, so n = 1)

t = the number of years (7 years)

Plug these values into the formula:

A = 2400(1 + 0.02/1)^(1*7)

A = 2400(1 + 0.02)⁷

A = 2400(1.02)⁷

A = 2400(1.144877)

A ≈ $2,747.70

So, the balance in the account after 7 years will be approximately $2,747.70.

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.

r = 5 + 4 cos θ

Answers

Explaining how to determine the symmetry of a polar graph based on the given equation r = 5 + 4 cos θ.

To determine the symmetry of the graph r = 5 + 4 cos θ, we can substitute (-θ) for θ in the equation and check if the resulting polar equation remains the same, indicating symmetry about the origin.

If replacing (-θ) gives us the same equation, the graph is symmetric about the y-axis. If replacing (π - θ) gives the same equation, then the graph is symmetric about the x-axis.

In this case, replacing (-θ) in r = 5 + 4 cos θ gives r = 5 + 4 cos(-θ), which simplifies to r = 5 + 4 cos θ, indicating symmetry about the y-axis.
