The percentage of actual yield is 60.66%.

The percentage of a number is the hundredth part of that number.

Given that the total yield is 872.7 grams and the actual yield is 529.4 grams.

The percentage is calculated by the formula given below.

[tex]Percentage\; of\; Yield = \dfrac {Actual \;Yield }{ Total\; Yield}\times 100[/tex]

Substituting the values, we get the percentage,

[tex]Yield \;\% = \dfrac {529.4}{872.7}\times 100[/tex]

[tex]Yeils\;\%=60.66\;\%[/tex]

Hence we can conclude that the percentage of actual yield is 60.66%.

The polynomial is a binomial

The coefficients are the invested amounts

From the question, we have the following parameters that can be used in our computation:

Polynomial expression = 400x^8 + 600x^6

The above has two terms

So, it can be classified as a binomial

From the question, we have:

investing $400 for 8 years and $600 for 6 years

Step-by-step explanation:

Answer:

Domain:— [ x ≥ -2, x ≤ -3 ]

Range:— [ y ≥ 0 ]

Step-by-step explanation:

You may use graphing calculator to draw a graph and examine the graph’s domain and range. However, I’ll explain further about the graph of quadratic in a surd.

First, factor the quadratic expression in the surd:—

[tex]\displaystyle \large{f(x)=\sqrt{(x+3)(x+2)}}[/tex]

We can find the x-intercepts by letting f(x) = 0.

I’ll be separating in two parts — one for finding x-intercept and one for finding y-intercept.

__________________________________________________________

Finding x-intercepts

Let f(x) = 0.

[tex]\displaystyle \large{0=\sqrt{(x+3)(x+2)}}[/tex]

Solve for x, square both sides:—

[tex]\displaystyle \large{0^2 = (\sqrt{(x+3)(x+2)})^2}\\\displaystyle \large{0=(x+3)(x+2)}[/tex]

Simply solve a quadratic equation:—

[tex]\displaystyle \large{x=-3,-2}[/tex]

Therefore, x-intercepts are:—

[tex]\displaystyle \large{\boxed{x=-3,-2}}[/tex]

__________________________________________________________

Finding y-intercept

Let x = 0.

[tex]\displaystyle \large{f(x)=\sqrt{(0+3)(0+2)}}\\\displaystyle \large{f(x)=\sqrt{3 \cdot 2}}\\\displaystyle \large{f(x)=\sqrt{6}}[/tex]

Therefore, y-intercept is:—

[tex]\displaystyle \large{\boxed{\sqrt{6}}}[/tex]

__________________________________________________________

However, I want you to focus on x-intercepts instead. We know that the square root only gives you a positive value. That means the range of function can only be y ≥ 0.

For domain, first, we have to know how or what the graph looks like. You can input the function in a graphing calculator as you’ll see that when x ≥ -2, the graph heads to the right while/when x ≤ -3, the graph heads to the left. This means that the lesser value of x-intercept gets left and more value get right.

See, between -3 < x < -2, there is no curve, point or anything between the interval. Therefore, -3 < x < -2 does not exist in function.

Hence, the domain is:—

x ≥ -2, x ≤ -3

Answer:

  (h)  ST, ∠S, ∠R

Step-by-step explanation:

In general the Law of Sines is applicable when you have two angles and a side. The solution of the triangle will be unique if the given side is opposite the largest angle.

These conditions are met in choice h.

  x/sin(S) = ST/sin(R)

  x = sin(S)·ST/sin(R) = sin(34°)·7/sin(92°)

  x ≈ 3.917

__

Additional comment

Here's why the other choices don't work.

  (f) These values would require sin(R) = 15.3/8.1×sin(38°) ≈ 1.163. No angle has a sine of this value, so no triangle can be formed with these values.

  (g) The given angle is between the given sides, so the Law of Cosines is needed for solving the triangle.

  (j) Three angles are given, but no sides are given. The lengths of the sides, including x, cannot be determined.

Using proportions, it is found that the sales tax is of 8%.

A proportion is a fraction of a total amount.

In this problem, he buys a shirt for $32.00, then the second at 35% off, hence the price of the second shirt is:

P = (1 - 0.35) x 200 = 0.65 x 20 = $13.

The total price of the shirts is:

T = $32.00 + $13.00 = $45.00.

Hence, he pays $3.60 in taxes, and the sales tax is given by:

Tax = (3.6/45) x 100% = 8%.

Answer: No, this is false

Step-by-step explanation:

    Difference of [tex]\frac{1}{5}[/tex] and [tex]\frac{1}{10}[/tex],

[tex]\frac{1}{5}[/tex] - [tex]\frac{1}{10}[/tex] = [tex]\frac{2}{10}[/tex] -  [tex]\frac{1}{10}[/tex]  =  [tex]\frac{1}{10}[/tex]

   [tex]\frac{1}{2}[/tex] is equal to [tex]\frac{5}{10}[/tex]. Since 1 is closer to 0 than it is to 5, the answer is no, this is false.

The sum of the angle measures is 180 degrees

  -->[tex](3x + 28)+(5x + 52) +(2x -10) = 180\\10x + 70 = 180\\10x = 110\\x = 11[/tex]

Since x= 11, angle c = 2(11) - 10= 12

Answer:

The picture is too blurry to see, so let me explain how you find the answer for yourself...

Step-by-step explanation:

Basically, time is the y-axis (up and down), and # of rebounds is the x-axis (left and right). The question asks for rebounds made in 15 minutes, so first find the 15 mark on the left of the graph. Trace that line across the graph to the right (use ur finger if you have to) until you hit a dot. Trace the line that the dot is on down to the bottom of the graph. The number you hit will be your answer (# of rebounds).

Lemon Squash                  If you put 90ml of concentrate in a glass, how

2 parts concentrate          water should be added?

to 5 parts water                 x  ml.

Ratio:  2:5 or 2/5

Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

2/5 = 90/x ( x = the unit (ml)/ how many ml of water)

Cross multiplication of the above equation will give us:

2x = 90 x 5 = 450

Dividing both sides by 2 we will get:

x = 450/2 = 225

Therefore, if we put 90ml of concentrate in a glass, the amont of water to be added is 225ml.

I hope this answer helps!
