Lines of symmetry is when all points touch each other so, #1 Is 5 Lines #2 Is No Because it has no lines that touch. #3 Is 4 Because its a rectangle and rectangles have 4 points so that would be 4 cause 4 points equals 4 lines. #4 Is No because Triangles have no lines. These Answers are for the first questions 1-4

What is the length of JK¯¯¯¯¯, to the nearest tenth of a millimeter? 4.5 mm 5.6 mm 8.3 mm 19.9 mm A horizontally-aligned scalene

Leokris [45]

Answer:

5 = side a

3 = side c

angle B = 62 degrees

JK is side b

Use the Law of Cosines to find the length of side b.

b^2 = a^2 + c^2 − 2ac cos(B)

b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)

b^2 = (25 + 9) − 30 x 0.469

b^2 = 34 - 30 x 0.469

b^2 = 34 - 14.084

b^2 = 19.916

b = √19.916

b = 4.463

Rounded to the nearest tenth is 4.5 mm.

Hope this helps!

Given the function F(t) = 34000(.98)' describe whether this function is growing or decaying, and by what percent. What is the in

Eduardwww [97]

The function F(t) = 34000(.98)^t, since b = 0.98 < 1, hence the function is decaying and the initial value of the expression is 34,000.

<h3>Exponential equation</h3>

The inverse of exponential equation is logarithmic equation. The standard exponential equation is expressed as;

y = ab^x

where

a is the initial value

b determine the growth rate or decay.

If the value if b < 1, then it is a decay otherwise it is growth.

Natalie is playing the Integer Game and only shows you the four cards shown below. She tells you that the rest of her cards have

leva [86]

Missing part of question

(a) If all matching cards will increase her score by 18, what are the matching cards

(b) If all matching cards will decrease her score by 12, what are the matching cards

See attachment for cards

Answer:

(a) 9 card number 2 or 6 card number 3

(b) 6 card number -6

Step-by-step explanation:

Given

The number on the cards are: 2, 3, -6 and 4

Solving (a): An increment of 18

From the card numbers attached, there are 3 positive numbers and 1 negative number

If any of the card numbers is to increase her score, then the card number must be positive. So, we have: card numbers 2, 3 and 4 that fit in this category.

Next, for a card number to give an increment of 18; the card number must be a factor of 18.

So, we have:

$\frac{18}{2} = 9$
