Answer:
625
Step-by-step explanation:
First, you have to convert 0.2 grams to mg. To do this, multiply 0.2 by 1000. This yield 200. Now 200 is what percent of 32.
200 * 100 / 32
= 625

What are the period and phase shift for f(x) = -4 tan(x − n)? (1 point)
T
Period: n; phase shift: x =
2
Period: n; phase shift: x = n
TT
Period: 2n; phase shift: x =
2
Period: 2n; phase shift: x = 0
Answer:
Period: [tex]\pi[/tex]
Phase shift: n
Step-by-step explanation:
Tangent function:
Has the following format:
[tex]f(x) = \tan{ax - n}[/tex]
In which the period is [tex]\frac{\pi}{x}[/tex] and the phase shift is n.
In this question:
[tex]f(x) = -4\tan{(x-n)}[/tex]
[tex]a = 1[/tex], and thus, the period is [tex]\pi[/tex], with a phase shift of n.
given the points (-4,8)and(6,-12)
1 Determine the midpoint of the line segment connecting the points.
2 Determine the distance separating the two points
Answer:
1.
[tex]midpoint = ( \frac{ - 4 + 6}{2} , \: \frac{ - 12 + 8}{2} ) \\ = (1, \: - 2)[/tex]
2.

Answer:
A. perhaps 0 to 7 days
B. the radius in mm at the start of the study
C. 0.114 mm/day
Step-by-step explanation:
A. It is always problematic to determine the reasonable domain for an exponential growth function. You can always limit the domain to the length of time for which the function is said to model the growth. It is difficult to say how much beyond that time period the exponential growth can be extrapolated, as most systems run into limits to growth.
Here, the base of the exponential term is 1.01 = 1 + 1%. This tells you the growth rate is 1% per day. The study concludes when the radius was 11.79/11.00 = 1.071818... ≈ 1 + 7.2% times the original size. That is, the study lasted approximately 7 days.
The question in part C has you look at the size on day 7, which is apparently the last day of the study. It is not clear that the model is at all useful beyond the end of the period it is intended to describe.
A reasonable domain for the growth function is 0 to 7 days.
__
B. The function gives the radius of the algae after d days. When d=0 (the y-intercept), the function gives the radius of the algae after 0 days. That is the meaning of the y-intercept is the initial radius of the algae (at the beginning of the study).
The y-intercept is always the "initial value", the value when the independent variable is zero. You have to look at the function definition to see what it is the initial value of.
__
C. The average rate of change is the difference in function values divided by the difference in time between them. Here, the attached table tells us that is ...
(f(7) -f(2))/(7 -2) = (11.793 -11.221)/5 = 0.572/5 = 0.1144 . . . mm/day
The units of the "average rate of change" are the units of the slope of the curve on the graph: the y-axis units divided by the x-axis units. Here, that is mm/day.

4. Which statement is true about the values of two expressions below?
Expression A: 3x(8+4)
Expression B. 8+4
A. The value of expression B is 3 times the value of expression A.
B. The value of expression A is 3 times the value of expression B.
C. The value of expression A 3 times more the value of expression B.
D. The value of expression B is 3 times more than the value of expression A.
Answer:
Both B and C should be correct
Step-by-step explanation:
I'm assuming the x in Expression A is a multiplication symbol. If it is not, please tell me and I will change my answer.
Expression B has the value of 8+4 or 12.
Expression A is 3 times (8+4). You could also say that Expression A is 3 times Expression B.
Since both answer B and C say this, they should both be correct.

Answer: True
Step-by-step explanation:
The subjects of an experiment should be selected at random so that they
represent the population is true.
Once the sample size has been decided, a sample should be taken from the sample size which will represent the population. This gives everyone an equal chance of being selected as there's no bias.

Answer:
Step-by-step explanation: She has 2 more nickels then dimes not 2 times more therefore answers B and D are incorrect. C is incorrect because it has that there are 2 more dimes than nickels. A is correct because it says that there are c dimes, and then c +2 nickels.

Answer:
Total cost = $6.61
Step-by-step explanation:
Given the following data;
Cost of breaded chicken = $5.68/lb
Quantity of breaded chicken = ¼
Baked chicken = $6.92/lb
Quantity of baked chicken = ¾
To find the total cost;
First of all, we would determine the cost of breaded chicken and baked chicken.
Cost of breaded chicken = ¼ * 5.68
Cost of breaded chicken = $1.42
Cost of baked chicken = ¾ * 6.92
Cost of baked chicken = 20.76/4
Cost of baked chicken = $5.19
Total cost = Cost of breaded chicken + Cost of baked chicken
Total cost = 1.42 + 5.19
Total cost = $6.61
The formula for the area of a parallelogram is A = bh, where b is the base and h is the height.
A parallelogram that is not drawn to scale. The height is labeled (x minus 4) centimeters. The base is labeled (2 x squared + 2 x minus 6) centimeters.
Which simplified expression represents the area of the parallelogram?
Answer:
Area = 2x^3 - 6x^2 - 14x + 24
Step-by-step explanation:
h = x - 4
b = 2x^2 + 2x - 6
Area = b * h
Area = (x - 4)(2x^2 + 2x - 6) Multiply through by x
Area = 2x^3 + 2x^2 - 6x - 8x^2 - 8x + 24 Multiply through by -4
Area = 2x^3 + (2x^2 - 8x^2) - 6x - 8x + 24 Collect like terms.
Answer
Area = 2x^3 - 6x^2 - 14x + 24

Someone pls help…. We need to find m angle f
Answer:
m<F = 95°
Step-by-step explanation:
We'll begin by calculating the value of x. This can be obtained as follow:
m<C = 50
m<A = (10x – 5)
m<B = m<G = (2x + 15)
m<C + m<A + m<B = 180 (Sum of angles in a triangle)
50 + (10x – 5) + (2x + 15) = 180
50 + 10x – 5 + 2x + 15 = 180
50 – 5 + 15 + 10x + 2x = 180
60 + 12x = 180
Collect like terms
12x = 180 – 60
12x = 120
Divide both side by 12
x = 120 / 12
x = 10
Finally, we shall determine the value of m<F. This can be obtained as follow:
m<F = m<A
But
m<A = 10x – 5
x = 10
Therefore,
m<F = 10x – 5
m<F = 10(10) – 5
m<F = 100 – 5
m<F = 95°
3. Mrs. Baumgartner draws a pair of supplementary angles and tells the class that
the angle measures are (4x +30)' and (2x + 6).
a. Write an equation to determine the value of x. Solve for x. SHOW ALL WORK
Answer:
Equation: 4x + 30 + 2x + 6 = 180
Answer: x = 24
Step-by-step explanation:
The sum of the measures of supplementary angles is 180 deg.
Equation:
4x + 30 + 2x + 6 = 180
Solution:
4x + 30 + 2x + 6 = 180
Add like terms on the left side.
6x + 36 = 180
Subtract 36 from both sides.
6x = 144
x = 24
Answer:
X=24
Step-by-step explanation:
Supplementary angles = 180°
4x+30+2x+6=180
Combine like terms> 4x+2x=6x
Add: 30+6=36
6x+36=180.
Subtract 36 on both sides. > 36-36=0. 180-36=144.
Drop what you have left> 6x 144
Divide by 6. > 6/6= 1. 144/6=24.
X=24

you sight a rock climber on a cliff at a 32° angle of elevation. your eye level is 5.5 feet above the ground and you are 1000 feet from the base of the cliff. what is the approximate height of the rock climber from the ground?
Answer:
630 feets
Step-by-step explanation:
From the triangle attached :
Using trigonometry, the height h, which is the height of climber to your eye level :
Tan θ = opposite / Adjacent
Tan 32 = h / 1000
h = tan 32 * 1000
h = 0.6248693 * 1000
h = 624.86935
Height from the ground :
624.86935 + 5.5
= 630.369 feets
= 630 feet

solve y/2 + 22 =38 for y
Answer:
y = 32
Step-by-step explanation:
[tex]\frac{y}{2}+22=38\\\frac{y}{2}=16\\y=32[/tex]
Answer:
y=32
Step-by-step explanation:
y/2 + 22 =38
Subtract 22 from each side
y/2 + 22-22 =38-22
y/2 = 16
Multiply each side by 2
y/2 *2 =16*2
y = 32
When a triangle is inscribed in a semicircle where a diameter of the circle is a side of the triangle, the triangle formed is always a right triangle. If an isosceles triangle (two equal sides) is inscribed in a semicircle with a radius of 9 inches, find the length of the two legs of the triangle.
Answer:
Step-by-step explanation:
diameter = 18 inches
each leg = 18/√2 = 9√2 ≅ 12.7 inches
The length of the two legs of the isosceles triangle is 9√2.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
When a triangle is inscribed in a semicircle with one side being the diameter of the circle, a right triangle is always created.
Also, the radius of semicircle is 9 inches,
Since, the isosceles triangle inscribed in the semicircle.
Sides of an isosceles triangle are equal, therefore the corresponding angle will also equal.
The sum of all three angles of a triangle is 180°
x+x+90 = 180
2x = 90
x=45
radius of circle is 9 inches, therefore diameter of circle = 18 inches
Apply sin rule,
18/sin90 = x/sin45
18/1 = x/1/√2
x= 9√2
The length of the side of the isosceles triangle is 9√2.
