Answer:

[tex]\frac{x^2}{25}+\frac{y^2}{64}=1[/tex]

Step-by-step explanation:

If the ellipse has a vertical major axis of length 16, then

[tex]2a=16[/tex]

[tex]\Rightarrow a=8[/tex]

If the ellipse has the length of the minor axis to be 10, then;

[tex]2b=10[/tex]

[tex]\Rightarrow b=5[/tex]

The equation of the ellipse is given by;

[tex]\frac{x^2}{b^2}+\frac{y^2}{a^2}=1[/tex]

Thus;

[tex]\frac{x^2}{5^2}+\frac{y^2}{8^2}=1[/tex]

Answer: OPTION C (119π cm²)

Step-by-step explanation:

Yon can use the following formula for calculate the surface area of a cone:

[tex]SA=rl\pi+r^2\pi[/tex]

Where r is the radius and l is the slant height.

Based on the figure shown attached, you have that:

[tex]r=7cm\\l=10cm[/tex]

Therefore, when you susbtitute these values into the formula shown above, you obtain that the surface area of the cone is:

[tex]SA=(7cm)(10cm)\pi+(7cm)^2\pi=119\pi[/tex]cm²

Answer:

The correct answer option is C. 119[tex]\pi^2[/tex]

Step-by-step explanation:

We are given the radius of the base of the cone and its height and we are to find its surface area.

We know that the surface area of the cone is given by: [tex]\pi rl +\pi r^2[/tex]

Substituting the given values in the above formula to get:

Surface area of cone = [tex] \pi \times 7 \times 10 + \pi \times 7^2 =[/tex] 119

Answer:

$4.99

Step-by-step explanation:

If she pays with $20 and recieves $5.03 in change, her total cost was 20 - 5.03 or $14.97. If each pair of socks is the same amount, 14.97 / 3 will give you the amount per each pair. 14.97 / 3 = $4.99

The cost in dollars and cents for each pair of socks is $4.99

The first step is to determine the total cost of the three pairs of socks

Total cost of the socks bought = amount paid - change received

$20 - $5.03 = $14.97

The second step is to determine the cost of each pair of socks

Cost of each pair of socks = total cost of socks / pairs bought

$14.97 / 3 = $4.99

The only zero of the function f(x) = x^2 - 8x + 16 is x = 4.

The zeros of a function, f(x), represent the values of x that make the function equal to zero. To find the zeros of the given function, f(x) = x^2 - 8x + 16, we need to solve the equation f(x) = 0.

Let's set the equation equal to zero and solve for x:

x^2 - 8x + 16 = 0

To solve this quadratic equation, we can use factoring or the quadratic formula. In this case, the equation can be factored as:

(x - 4)(x - 4) = 0

This means that the equation is equivalent to (x - 4)^2 = 0.

To find the zeros, we set (x - 4)^2 = 0 and solve for x:

(x - 4) = 0

x = 4

So, the only zero of the function f(x) = x^2 - 8x + 16 is x = 4.

In other words, the graph of the function f(x) = x^2 - 8x + 16 intersects the x-axis at the point (4, 0).

Answer:

[tex]5.3\ years[/tex]  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]A=\$9,000\\ P=\$6,500\\ r=0.0625\\n=2[/tex]  

substitute in the formula above  and solve for t

[tex]9,000=6,500(1+\frac{0.0625}{2})^{2t}[/tex]  

[tex]1.38462=(1.03125)^{2t}[/tex]  

applying log both sides

[tex]log(1.38462)=(2t)log(1.03125)[/tex]  

[tex]t=log(1.38462)/2log(1.03125)=5.3\ years[/tex]  

Answer: 14.4

Step-by-step explanation:

Answer:

Step-by-step explanation:

(I assume it's [tex]12sin^2 x -13 sinx +3 = 0[/tex])

Start by setting [tex] sinx = y [/tex] (or whichever letter you prefer). Your equation becomes [tex] 12y^2 -13y +3 = 0[/tex] . Solving for y you get [tex]y = \frac {-(-13) \pm \sqrt{13^2 - 4*3*12} } {2*12} =\frac{ 13 \pm \sqrt{13^2-12^2}} {24} = \frac {13 \pm5 }{24}\\ y = \frac {18} {24} = \frac 34; y= \frac 8 {24} = 1/3[/tex]

But we're not done yet. Since we said  [tex] sinx = y [/tex], you need to solve both  [tex] sinx = \frac 3 4 [/tex] and  [tex] sinx = \frac 1 3 [/tex], whose solutions are the inverse sine of said values, plus any number of complete rotations.

where (h, k) are the coordinates of the centre and r is the radius

Answer:

[tex]\large\boxed{A=144\pi\ in^2\approx452.16\ in^2}[/tex]

Step-by-step explanation:

A diameter is two times longer than a radius. Therefore, if the diameter

d = 24in, then the radius r = (24in) : 2 = 12in.

The formula of an area of a circle:

[tex]A=\pi r^2[/tex]

Substitute:

[tex]A=\pi(12)^2=144\pi\ in^2[/tex]

[tex]\pi\approx3.14[/tex]

Then

[tex]A\approx(144)(3.14)=452.16\ in^2[/tex]

Final answer:

The area of a bicycle wheel with a diameter of 24 inches can be calculated using the formula A = πr² and is approximately 452.16 square inches.

Explanation:

To calculate the area of a bicycle wheel with a diameter of 24 inches, we first need to find the radius of the wheel. The radius is half of the diameter, so in this case, the radius is 12 inches. The formula to find the area of a circle is A = πr², where A is the area and r is the radius. Substituting the known radius into the formula, we find:

A = π * (12 inches)² = π * 144 inches² ≈ 3.14 * 144 inches² = 452.16 square inches

Therefore, the area of the bicycle wheel is approximately 452.16 square inches.

Answer:

A.) The red cylinder.

Step-by-step explanation:

For a cylinder:

V = (1/3)(pi)r^2h

Red:

V = (1/3)(pi)(2^2)(4) = 16pi/3

Blue:

V = (1/3)(pi)(1^1)(8) = 8pi/3

Since 16pi/3 is greater than 8pi/3, the red cylinder has a greater volume.

Answer:

Step-by-step explanation:

To take a radian measure that is over 2π (360°), to an equivalent measure that is less than 2π, subtract intervals of 2π until the value is where you want it.

(23π)/4 - 2π =  (23π)/4 - (8π)/4 = 15π/4

This is still more than 2π, so subtract another 2π...

(15π)/4 - 2π = (15π)/4 - (8π/4) = (7π)/4

This is less than 2π, so stop here...

following similar steps on the other 3 given radian measures give you...

(18π)/5 = (8π)/5

(22π)/9 = (4π)/9

(19π)/3 = π/3

To convert from degrees to radians, multiply the degree measure by π/180°

We have

60°(π/180°) = (60°π)/180° = π/3

288°(π/180°) = (288°π)/180° = (8π)/5

315°(π/180°) = (315°π)/180° = (7π)/4

80°(π/180°) = (80°π)/180° = (4π)/9
