The Graph Shows How Much Insulin, In Micrograms (mcg), Is In A Patient's Body After Receiving An Injection.

Answers

Answer 1

By using the first two points on the graph, we conclude that exponential equation is:

y = 200*(0.4)^t

What is the equation?

We assume that the equation is an exponential decay of the form:

y = A*(r)^t

When t = 0 we have:

y = A

On the graph we can see that the initial value is 200, then A = 200, so we have:

y = 200*(r)^t

By looking at the graph we can see that:

80 = 200*(r)^1    (this is the second point graphed).

Solving for r we get:

80 = 200*(r)

80/200 = r = 0.4

Then the exponential equation is:

y = 200*(0.4)^t

What is the Corresponding Angles Theorem?

Two angles that correspond to each other are congruent based on the corresponding angles theorem.

Thus:

5x + x = 180° (linear pair)

6x = 180

x = 180/6

x = 30

Therefore:

x = a (corresponding angles)

a = 30°

Therefore, based on the corresponding angles theorem, a = 30°.

Ok so the general form of a circle is given by;

(x-a)²+(y-b)²=r²

where a and b are the coordinates of the center

and r is the radius of the circle

For this case we know that the center is (5,-7)

So the general equation of the circle would be;

[tex](x - 5) {}^{2} + (y - ( - 7)) {}^{2} = r {}^{2} [/tex]

[tex](x - 5 {}^{2} + (y + 7) {}^{2} = r {}^{2} [/tex]

Since we know that (-3,-1) is a point on that circle, we can say that it satisfies the equation of the circle;

[tex]( - 3 - 5) {}^{2} + ( - 1 + 7) {}^{2} = r {}^{2} [/tex]

[tex]r {}^{2} = ( - 8) {}^{2} + ( 6) {}^{2} [/tex]

[tex]r {}^{2} = 64 + 36 = 100[/tex]

So now,

[tex](x - 5) {}^{2} + ( {y + 7)}^{2} = 100[/tex]

A.) 45.2
B.) 43.1
C.) 42
D.) 34.8

Answers

Answer:

D

Step-by-step explanation:

using the sine ratio in the right triangle

sin20° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{11.9}{c}[/tex] ( multiply both sides by c )

c × sin20° = 11.9 ( divide both sides by sin20° )

c = [tex]\frac{11.9}{sin20}[/tex] ≈ 34.8 ( to the nearest tenth )

A circle is translated 4 units to the right and then reflected over the x axis. What statement will always be true of the circle at the new location?

Answers

Answer:

The statements are not given, so i will answer it in the most general way possible:

First, let's recall two things:

Horizontal translation.

For a number A positive, we can move the graph of f(x) by A units to the right by the transformation g(x) = f(x - A)

Reflection over x

For a point (x, y), a reflection over the x-axis transforms this point into (x, - y).

Now let's analyze the problem:

A generic circle, of radius R and centered in the point (a, b) can be written as:

(x - a)^2 + (y - b)^2 = R^2.

Now let's translate this 4 units to the right:

(x - 4 - a)^2 + (y - b)^2 = R^2.

or in standard circle notation:

(x - (4 + a))^2 + (y - b)^2 = R^2.

Now the circle is centered in the point (a + 4, b).

Now let's do a reflection over the x-axis.

This means that the sign of y changes, so now we have:

(x - (4 + a))^2 + (-y - b)^2 = R^2.

But because the term with y is squared, this is the same than:

(x - (4 + a))^2 + (y + b)^2 = R^2.

Or, in standard circle notation:

(x - (4 + a))^2 + (y - (-b))^2 = R^2.

Then the circle is now centered in point (a + 4, -b).

So now you know where the circle is located, and also you can see that the radius of the circle never changed.

If a fair coin is tossed 4 times, what is the probability, rounded to the nearest thousandth, of getting at least 2 tails?

Answers

Answer:

You flip a coin 4 times, with 2 possibilities every flip, heads or tails. So, every time you throw there's a 50% chance you'll throw tails. so it would be 1/2

The probability of getting at least 2 tails is 0.688.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Given that, a fair coin is tossed 4 times.

So, sample space is

S = {HHHH, TTTT, HHHT, HHTH, HTHH, THHH, HHTT, HTTH, HTHT, THHT, THTH, TTHH, HTTT, THTT, TTHT, TTTH}

Now, total number of outcomes =16

Number of favorable outcomes = 11

Probability =11/16

= 0.6875

≈ 0.688

Therefore, the probability of an event is 0.688.

A = [ ? ] ft?
Notice that only half of the circle is included in the figure!

Answers

The figure contains a triangle and a semicircle

The area of the figure is 49.12 square feet

How to determine the area

The dimension of the triangle is:

Base = 8 ft

Height = 6ft

So, the area is:

Area = 0.5 * Base * Height

This gives

Area = 0.5 * 8ft * 6ft

Evaluate

Area = 24 square feet

The radius of the semicircle is:

r = 4 ft.

So, the area is:

[tex]Area = 0.5\pi r^2[/tex]

This gives:

Area = 0.5*3.14 * 4^2

Area = 25.12 square feet

Add the calculated  areas.

Total = 24 square feet + 25.12 square feet

Total = 49.12 square feet

Hence, the area of the figure is 49.12 square feet
