I NEED HELP ON QUESTION B AND C ASAP.

ipn [44]

Answer:

See below

Step-by-step explanation:

Assumed the dimensions of the top and bottom parts are identical.

Since the cylindrical part has total height of 1.8 cm and the hemisphere volume is transferred to bottom part and the cone part is still full, the value of h is the difference of the total height of cylinder and full part of the top section of cylinder:

h = 1.8 cm - 0.3 cm = 1.5 cm

Find the volume of sand in the bottom part. It consists of a hemisphere and a cylinder of 1.5 cm height.

V(cylinder) = πr²h = 3.14*(2.6/2)²*1.5 ≈ 7.96 cm³
V(hemisphere) = 2/3πr³ = 2/3*3.14*(2.6/2)³ ≈ 4.6 cm³

<u>Total sand in the bottom part:</u>

7.96 + 4.6 = 12.56 cm³

<u>Time taken:</u>

12.56 / 0.05 = 251.2 seconds = 4 min 11.2 seconds

1. Segment AB has the coordinates given.

denpristay [2]

The first image has a coordinate of A'(1, 6) B'(-3, 7)

<h3>How to calculate the coordinates of an image after a translation?</h3>

Translation can be defined as movement in a straight line.

Given the rule: (x,y) → (x + 3, y - 1) and A(-2,7) B(-6,8)

That means: A(x = -2, y =7) B(x = -6, y = 8)

Thus the translation will be:

A'(-2 +3, 7-1) B'(-6+3, 8-1) = A'(1, 6) B'(-3, 7)

Therefore, the coordinate of the image is A'(1, 6) B'(-3, 7)

Find the distance between M(-2,3) and N(8,2)

AnnZ [28]

Answer:

$d=\sqrt{101}$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(8-(-2))^2+(2-3)^2}$

$d=\sqrt{(8+2)^2+(-1)^2}$

$d=\sqrt{(10)^2+1}$

$d=\sqrt{100+1}$

$d=\sqrt{101}$

BRAINLIEST ANSWER TO FIRST ANSWERER!!!!

mina [271]

Answer:

Option C. $tan(B)=2.29$

Step-by-step explanation:

we know that

In the right triangle ABC

The tangent of angle B is equal to the opposite side angle B divided by the adjacent side angle B

$tan(B)=\frac{AC}{AB}$

substitute the values

$tan(B)=\frac{16}{7}=2.29$

1.What letter can you draw on a coordinate plane to help you remember the order of the quadrants?

weeeeeb [17]

1. I would call quadrants i, ii, iii, iv as a, b, c, d

<span>2.Which type of variables are usually on the y-axis and represent output?
</span>they usually are the dependent variables, that is, they depend on the x value, such as velocity, price, income.

3.Which type of variables are usually on the x-axis and represent input?
those are the independent variables such as time, distance, price.

<span>4.Which type of slope is represented on a graph as a horizontal line? </span>
the slope of an horizontal line is zero.

<span>5.Find the slope of 2x + 4y = 12
</span>the general form of the line is:
4y = - 2x + 12
y = -(1/2)x + 3

hence the slope is -1/2
