Jacob helped his grandma peel potatoes for the family's dinner. His grandma peeled 4 times as many potatoes as Jacob peeled. If

const2013 [10]

All together they peeled 20
J:jacob
G:grandma
4J=G. Since she peeled 4 times as he did
4J=16
J=4
So jacob peeled 4 potatoes
All in all:J+G
4+16=20

Would You Rather...

First we want to get them into similar terms so it makes more sense.

Let's go for mph since that is more common.

40 mph

50fps (feet per second)

To get this into mph we divide it by 1.467

34 mph - ish

So I would not mind either as they are quite similar in speed :)

(unless I am abosultely wrong haha)

Round to the nearest tenth.

laila [671]

Answer:

8.2 units

Step-by-step explanation:

Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC

Recall the Law of Cosines

$a^2=b^2+c^2-2bc\cdot cos(A)$

Identify angles and sides

$m\angle A=23^\circ\\a=BC=?\\b=AC=14\\c=AB=6$

Solve for side "a"

$a^2=b^2+c^2-2bc\cdot cos(A)\\\\a^2=14^2+6^2-2(14)(6)\cdot cos(23^\circ)\\\\a^2=196+36-168cos(23^\circ)\\\\a^2=222-168cos(23^\circ)\\\\a=\sqrt{222-168cos(23^\circ)}\\ \\a\approx8.2$

Therefore, the length of line segment BC is about 8.2 units

When vector is added to vector , the resultant is vector such that . This resultant vector has components Rx=Ax+BxRx=Ax+Bx and R

SVETLANKA909090 [29]

Answer:

a. When vector is added to vector , the resultant is vector such that its magnitude and direction is proportional to the resultant magnitude and direction of the component vectors.

b. ∅ = $tan^{-1}$ (Rx/Ry)

Step-by-step explanation:

Vectors are used to express physical quantities with magnitude and direction. Vectors can be added by the parallelogram method or the triangular method of addition. the magnitude and direction of the resultant vector is usually proportional to the magnitude and direction of the component vectors.

The direction of the angle is found as

tan∅ = Rx/Ry

∅ = $tan^{-1}$ (Rx/Ry)

(a) State whether each of the following is a function. (6, 2), (8,2), (6,3), (12,3) Yes / No

Sloan [31]

Answer:

Not a function.

Step-by-step explanation:

The definition of a function specifies that no value of x can be paired with two or more different values of y.

In the given relation: {(6, 2), (8, 2), (6, 3), (12, 3)},

The input value of x = 6 has two corresponding output values (y-coordinates): 2 and 3.

Therefore, the given relation is not a function.
