Answer:
(a) -10d^4 +17d^2s -6s^2
Step-by-step explanation:
Use the distributive property to eliminate parentheses, then collect terms.
[tex](-2d^2+s)(5d^2-6s)=-2d^2(5d^2-6s)+s(5d^2-6s)\\\\=(-2d^2)(5d^2) +(-2d^2)(-6s)+s(5d^2)+s(-6s)\\\\=-10d^4+12d^2s+5d^2s-6s^2\\\\=\boxed{-10d^4+17d^2s-6s^2}[/tex]

A bag contains three types of candy (gumdrops, jelly beans, and jawbreakers). If
chosen at random, the probability of getting a gumdrop is 1/6 and the probability
of getting a jellybean is 1/3 What is the probability of getting a jawbreaker?
Answer:
P) = 1/2 jawbreaker
simplified P) 3/6 = 1/2 jawbreaker
Which both mean the same, so show simplified if asked and either answer if not asked would be marked high.
as 2/6 + 1/3 = 3/6
1 - 3/6 = 3/6
= 1/2 are the workings.
Step-by-step explanation:
Jelly bean = 1/3 = 2/6
Gumdrop = 1/6
2/6 + 1/6 = 3/6 = the difference of 1
1-3/6 = 3/6
Therefore; P) = 3/6 jawbreaker

Answer:
1.) C. 32
2.) Stem-and-leaf plot
Step-by-step explanation:
This is a stem-and-leaf plot. The stem represents tens and the leaves represent units. To make it easier to look at, it is equivalent to this:
20, 28, 29, 29, 31, 32, 36, 41, 42Now, to find the mean, add up all the numbers and divide the sum by the number of values.
(20 + 28 + 29 + 29 + 31 + 32 + 36 + 41 + 42)/9 = 288/9 = 32

Irene has a checking account. On Monday she writes a $160 check for groceries. Then she deposits $125
into her account. Finally, she writes another check for $40. What was the total change in the amount of
money in Irene's account on Monday?
A. $85
B. - $85
C. $75
D. -$75
E. $325
F. - $325
Answer:
D. - $75Step-by-step explanation:
We mark checks as negative and a deposit as positive:
- 160 + 125- 40Add up to get the total change of:
-160 + 125 - 40 = - 75Correct choice is D
Answer:
Answer :-
Here, Irene is having a checking account. First she write a check of $160. Then means it has an decrease money. (-160) Now, She deposit $125. This means Now, the balance is -160 + 125 = $-35. She again write a check of $40. (-40). Total change =>
-40 - 35

Answer:
6ft by 15ft
Explanation:
L1 = 10 ft
W1 = 4 ft
L2 = L1*(3/2)
W2 = W1*(3/2)
L2 = 10 ft times (3/2) = 15 ft
W2 = 4 ft times (3/2) = 6 ft

the height of each door on the plan is given 1,5cm but the height of each door is 1,92m is an actual size.show that the scale of the house is 1:128
Answer:
It is.
Step-by-step explanation:
1.5cm is in the plan.
1.92m is in real life.
We need to convert m to cm so 1.92m=192cm
The ratio is 1:128.
1.5cm in plan as is 192 cm in real life.We write that as the ratio of: 1.5 : 192.
We need to prove that it is the actual scale so we equal this ratio(1.5:192) and the other ratio(1:128):
1.5 : 192 = 1 : 128
Then we multiply the numbers that are in and out of the equation like this:
1.5 * 128 = 192 * 1
192 = 192 It is proven beacuse the numbers are equal. The scale of the house is 1:128
On the planet Tott, there are 9 frenks to every 8 vreels. If farmer Yoy
has 80 frenks on her rew farm, how many vreels are on the farm?
Round to the nearest tenth if rounding is needed?
Answer:
71.1 vreels on the farm
Step-by-step explanation:
Create a proportion where x is how many vreels are on the farm:
[tex]\frac{9}{8}[/tex] = [tex]\frac{80}{x}[/tex]
Cross multiply and solve for x:
9x = 640
x = 71.1
So, to the nearest tenth, there are 71.1 vreels on the farm.

2. Show that a. the points 3 + i,6,4 + 4i are vertices of right triangle
Answer:
Step-by-step explanation:
[tex]Z_1=3+i\\Z_2=6\\Z_3=4+4i\\\\||Z_2\ Z_1||^2=||-3+i||^2=9+1=10\\\\||Z_1\ Z_3||^2=||1+3i||^2=10\\\\||Z_2\ Z_3||^2=||-2+4i||^2=20\\\\And\ 10+10=20[/tex]
Using the converse of the Pythagorean's theorem, the triangle is right.
Using Pythagorean theorem, the points 3 + i, 6, and 4 + 4i indeed form the vertices of a right triangle.
The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).
Let's calculate the distances between the points and then check if the Pythagorean theorem holds for them.
Distance between points A (3 + i) and B (6):
Distance AB = |6 - (3 + i)|
= |6 - 3 - i|
= |3 - i|
= [tex]\sqrt{(3^2 + (-1)^2)[/tex]
= √10
Distance between points A (3 + i) and C (4 + 4i):
Distance AC = |4 + 4i - (3 + i)|
= |1 + 3i|
= [tex]\sqrt{(1^2 + 3^2)[/tex]
= √10
Distance between points B (6) and C (4 + 4i):
Distance BC = |4 + 4i - 6|
= |-2 + 4i|
= [tex]\sqrt{((-2)^2 + 4^2)[/tex]
= √20
Now let's check if the Pythagorean theorem holds for these distances:
Longest side: [tex]BC^2 = (\sqrt20)^2 = 20[/tex]
Sum of squares of shorter sides:
[tex]AB^2 + AC^2 = (\sqrt10)^2 + (\sqrt10)^2[/tex] = 10 + 10 = 20
Since the sum of the squares of the shorter sides is equal to the square of the longest side.
So, the points 3 + i, 6, and 4 + 4i are vertices of a right triangle.

Given the recursive sequence defined by:
tn=5tn-1 + 3tn-2
with ti=2 and t2 = 4
Which of the following would be the first 5 terms of the sequence?
Answer:
2, 4, 26, 142, 788
Step-by-step explanation:
Using the recursive rule and t₁ = 2, t₂ = 4 , then
t₃ = 5t₂ + 3t₁ = 5(4) + 3(2) = 20 + 6 = 26
t₄ = 5t₃ + 3t₂ = 5(26) + 3(4) = 130 + 12 = 142
t₅ = 5t₄ + 3t₃ = 5(142) + 3(26) = 710 + 78 = 788
First 5 terms are 2, 4, 26, 142, 788
