Answer: His temperature is 99°F

Step-by-step explanation:

Let's state what we know:

Steve's temperature was initially 102°F

Later it dropped 3°F lower

Since his temperature decreased we need to subtract 3 from 102 to see what his temperature is now

102-3=99

Answer:

f(x) and g(x) are inverses of each other

Step-by-step explanation:

To find the inverse of a function, swap the x's and y's and then solve for "y"

f(x) = 5x + 2

y  = 5x + 2

Swap:

    x = 5y + 2

  -2        - 2

x - 2 = 5y

Most secured loans are not high-interest loans and they are usually backed by collateral.

Secured loans demand the borrower to dedicate an asset or security as an assurance or collateral for the loan in order to get it.

For example:

Secured loans are often long-term loans; e.g, the average period of a house loan is 30 years, whereas vehicle loans run 4-5 years.

These kinds of loans are often repaid in monthly installments and have low-interest rates.

Answer:

For this question, we use the formula for the volume of a cylinder.

(formula for vol. of cylinder)

V = π[tex]r^{2}[/tex]h

Where 'π' represents pi(22/7 or 3.14), 'r' represents the radius which is being squared, and 'h' stands for the height.

We utilize the information that we know:

Which we then plug into our equation(volume of cylinder formula):

V = π[tex]r^{2}[/tex]h

904.78 = 3.14(6^2) · h

Next solve for the h(height).

904.78 = 3.14(36) · h

904.78 = 113.04 · h

904.78 = 113.04h

/113.04     /113.04

8.00406935598 = h, which we round to 8.

8 centimetres is the height of this cylinder.

Step-by-step explanation:

the decay or "half-life" of radioactive particles is really a big joke by nature, in my opinion.

it takes that much time for half of the amount to decay, so, naturally, one wound assume that after a second interval then the other half is gone.

but far from it. no, only the half of the originally remaining half is then gone (the half of a half is 1/2 × 1/2 = 1/4). and after another interval the half of the half of the half is then gone. and so on.

so, this creates a geometric sequence with the common factor (or ratio) if 1/2.

that means every term is created by multiplying the previous term by 1/2.

a.

how many "half-lives" in 1104 days ?

well, with every 138 days such a half-life is over.

so, the answer is how often 138 fits into 1104 :

1104 / 138 = 8

there are 8 "half-lives" of polonium-210 in 1104 days.

b.

how much polonium-210 is in the sample after 1104 days ?

since we have 8 half-lives, we need to multiply the original amount 8 times by 1/2. in other words by 1/2⁸.

2⁸ = 256

so, our calculation is

30 g × 1/256 = 0.1171875 g ≈ 0.12 g

so, the second answer option is correct.

The area of the shaded region in the given quadrant, to the nearest hundredth is: 4.57 ft².

Area of a quadrant = 1/4 × area of a circle = 1/4 × πr²

The figure has been partitioned into A, B, C to E.

The area of the shaded region = A + B

Step 1: Find the area of A:

Area of A = area of the square formed by D, A, and C - area of D + area of C.

Area of D = area of square - area of quadrant formed by A and C

Area of D = s² - 1/4 × πr² = 2² - 1/4 × π(2)²

Area of D = 0.86 ft²

Area D = area of C = 0.86 ft²

Area of D + area of C = 2(0.86) = 1.72 ft²

Area of A = 4 - 1.72 = 2.28 ft²

Step 2: Find the area of quadrants E and F

Area of quadrants E and F = 2(1/4 × πr²) = 2(1/4 × (3.14)(2)²)

Area of quadrants E and F = 6.28 ft².

Step 3: Find the area of B

Area of B = area of the biggest quadrant - area of quadrants E and F + area of square formed by D, A, and C

Area of B = 1/4 × πr² - 6.28 + 4

Area of B = 1/4 × π(4²) - 10.28

Area of B = 2.29 ft².

Step 4: Find the area of the shaded region

Area of the shaded region = A + B = 2.28 + 2.29

Area of the shaded region = 4.57 ft².

In conclusion, the area of the shaded region in the given quadrant, to the nearest hundredth is: 4.57 ft².

Solving the trigonometric equations, the times at which the pendulum's movement will be 8 meters from its starting position are of:

[tex]x = 8\pi + 16n\pi[/tex] seconds.

It is given by:

[tex]f(x) = -4\cos{\frac{x}{8}} + 4[/tex]

It is 8 meters from its starting position when f(x) = 8, hence:

[tex]f(x) = -4\cos{\frac{x}{8}} + 4[/tex]

[tex]8 = -4\cos{\frac{x}{8}} + 4[/tex]

[tex]4 = -4\cos{\frac{x}{8}}[/tex]

[tex]\cos{\frac{x}{8}} = -1[/tex]

We have that:

[tex]\cos{x} = -1 \rightarrow x = \pi + 2n\pi[/tex]

Hence:

[tex]\frac{x}{8} = \pi + 2n\pi[/tex]

[tex]x = 8\pi + 16n\pi[/tex] seconds.

Step-by-step explanation:

Answer: B: 24%

Step-by-step explanation:

The measure of all three angles is 81, 49.5 and 49.5 degrees.

According to the angle sum property of a triangle, the sum of all three interior angles of a triangle is 180 degrees. A triangle is a closed figure formed by three line segments, consisting of interior as well as exterior angles.

The angle sum property formula for any polygon is expressed as, S = (n − 2) × 180°, where 'n' represents the number of sides in the polygon. This property of a polygon states that the sum of the interior angles in a polygon can be found with the help of the number of triangles that can be formed inside it.

Given:

The triangle is isosceles which has two sides equal.

Also Two angles equals.

Let the equal angles are x.

third angle= 81 degree

Now, Using Angle Sum property

x+ +x + 81 = 180

2x= 180-81

2x= 99

x= 99/2

x= 49.5 degrees

Hence, the two smaller angles are 49.5 degrees.

Considering the given focus and directrix, the equation of the parabola is given by:

[tex]y = -2.375x^2[/tex]

The equation of a parabola, with a directrix in y, is:

[tex]y - k = a(x - h)^2[/tex]

In which:

In this problem, we have that the x-coordinate of the vertex is h = 0.

From the focus and the directrix, we have that:

k+C = -9.5

k - c = 9.5.

Hence k = 0, C = -9.5 = a = 0.25C = -2.375.
