What is the lateral area of the cone to the nearest whole number? The figure is not drawn to scale. NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!​

Answers

Answer:

25,120 sq. metres

Step-by-step explanation:

Find the diagram attached

Lateral surface area = πrl

r is the radius

l is the slant height

Given

r = 160/2 = 80m

l = √r²+h²

l = √80²+60²

l  = √6400+3600

l = √10,000

l = 100cm

Lateral surface area = 3.14 * 80 * 100

Lateral surface area = 25,120 sq. metres

y=x/4+1/2 find the x and y Pls help asap

Answers

Answer:

y = 1/4x + 1/2 and x = -2 +4y

Step-by-step explanation:

Solving it in a way that x/4 is a fraction and not division so you would make that 1/4x. y = x/4 +1/2 x/4 is 1/4x so then you subtract 1/2 from both sides to get y - 1/2 = 1/4x. You can then divide 1/4 on both sides. -1/2 divided by 1/4 is -2 and 1/4y. This will get your answer of x = 1/4y -2 for x. Y is just 1/4x + 1/2

What is the equation of a line that passes through the points (-3,4) and (2, 8

Answers

Answer:

y = 4/5x + 32/5

Step-by-step explanation:

(-3,4) and (2, 8)

Slope:

m=(y2-y1)/(x2-x1)

m=(8-4)/(2+3)

m= 4/5

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = 4/5(x + 3)

y - 4 = 4/5x + 12/5

y = 4/5x + 32/5

On Monday, a dental hygienist cleans teeth of 5 patients by the time she takes her lunch break at noon. On average, she is able to clean the teeth of 9 patients in 4 hours

PLEASE HELP!

Answers

y= 9/4x + 5
y = 9/4(2) + 5
y = 9.5
y= between 9-10 patients, round down to 9

The function that represents the number of patients she sees is; y = 9/4x + 5 and number of patients after 2 hours is 9 patients

How to write Functions?

We are given;

Number of patients the dental hygeinist cleans before lunch = 5

Average number that she cleans after lunch = 9 patients in 4 hours

Thus, number of patients per hour is 9/4

The formula for slope intercept form is;

y = mx + c

Thus, equation to represent the situation in the question is;

y = 9/4x + 5

At 2 hours after lunch, number of patients is;

y = 9/4(2) + 5

y = 9.5

Approximately 9 patients

When instructed to find the length of HJ in right

Are both students' equations correct? Explain

why.

H

28

O

G

Answers

See attachement for the diagram of the triangle

Answer/Step-by-step explanation:

To find the length of HJ, we can use different equations as follows:

✔️Recall: SOHCAHTOA

Let's take <G as the reference angle = 28°

Opposite side to reference angle = HJ

Hypotenuse = 20

Apply SOH.

Thus:

Sin 28° = opp/hyp

Sin 28° = HJ/20 (Alex's equation is correct).

Solving further, we would have:

HJ = Sin 28 * 20 ≈ 9.4

✔️Another way is by using <H as the reference angle.

m<H = 180° - (90° + 28°) (sum of triangle)

m<H = 62°

Adjacent side to reference angle (<H) = HJ

Hypotenuse = 20

Apply CAH:

Cos 62° = Adj/Hyp

Cos 62° = HJ/20 (Marlene's equation is correct)

Solving further, we would have,

HJ = Cos 62° * 20 ≈ 9.4

As you can see, the equation of both students are correct. Both would arrive at the same answer using any of the two equations.

Given:

The vertices of a parallelogram GHJK are K(1,2), J(5,2), G(0,8).

To find:

The coordinate of the vertex H.

Solution:

We know that the diagonals of a parallelogram bisects each other. It means the midpoint of the diagonals are same.

Let the coordinate of the vertex H are (a,b).

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

In parallelogram GHJK ,

Midpoint of diagonal GJ = Midpoint of diagonal HK

[tex]\left(\dfrac{0+5}{2},\dfrac{8+2}{2}\right)=\left(\dfrac{a+1}{2},\dfrac{b+2}{2}\right)[/tex]

[tex]\left(\dfrac{5}{2},\dfrac{10}{2}\right)=\left(\dfrac{a+1}{2},\dfrac{b+2}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{5}{2}=\dfrac{a+1}{2}[/tex]

[tex]5=a+1[/tex]

[tex]5-1=a[/tex]

[tex]4=a[/tex]

And,

[tex]\dfrac{10}{2}=\dfrac{b+2}{2}[/tex]

[tex]10=b+2[/tex]

[tex]10-2=b[/tex]

[tex]8=b[/tex]

Therefore, the coordinates of the vertex H are (4,8). Hence, option B is correct.

A capacitor holds a 8.89 x 10-7 C
charge when 32.0 V are applied to
it. What is its capacitance?

Answers

Answer:2.77*10^-8

Step-by-step explanation:

8.89*10^-7/32.0

The capacitance of the capacitor is approximately 2.78 x 10⁻⁹ Farads (F).

The capacitance of a capacitor can be calculated using the formula:

C = Q / V

Where C represents the capacitance, Q represents the charge stored in the capacitor, and V represents the voltage applied to the capacitor.

In this case, we are given that the charge stored in the capacitor is 8.89 x 10⁻⁷ C and the voltage applied is 32.0 V. Plugging these values into the formula, we get:

C = (8.89 x 10⁻⁷ C) / (32.0 V)

Simplifying the expression, we find:

C ≈ 2.78 x 10⁻⁹ F

The Farad is the SI unit of capacitance, representing the ability of a capacitor to store charge per unit voltage.
