Answer:
1. 10
2. 10
3. 12
4. [tex]3\sqrt{14}[/tex] or 11.22497216
Step-by-step explanation:
1. [tex]a^{2}+b^{2} =c^{2}\\\\a^{2} = 8^{2} = 64\\b^{2} = 6^{2} = 36\\c^{2} = a^{2} + b^{2} = 64 + 36 = 100\\c = \sqrt{100} = 10[/tex]
2. [tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 24^{2} = 576\\c^{2} = 26^{2} = 676\\b^{2} = c^{2} - a^{2} = 676 - 576 = 100\\b = \sqrt{100} = 10[/tex]
3.[tex]c^{2}-a^{2} =b^{2}\\\\a^{2} = 5^{2} = 25\\c^{2} = 13^{2} = 169\\b^{2} = c^{2} - a^{2} = 169 - 25 = 144\\b = \sqrt{144} = 12[/tex]
4. [tex]c^{2}-b^{2}=a^{2}\\\\b^{2} = 11^{2} = 121\\c^{2} = \sqrt{137}^{2} = 137\\a^{2} = c^{2} - b^{2} = 137 - 11 = 126\\a = \sqrt{126} = 3\sqrt{14} = 11.22497216[/tex]

Jose receives a $10 gift card for downloading music and wants to determine how many songs he can purchase. Each downloaded song costs $1.19. Write and solve an inequality to determine how many songs Jose can purchase. What does the solved inequality represent?
Answer:
One correct inequality is
1.19x≤10,
and the correct solution is
x≤8.
Explanation:
Let x be the number of songs Jose downloads. Each song has a cost of $1.19; this would give the total amount spent as 1.19*x, or 1.19x.
He has at most $10 to spend. This means he can spend less than $10 or exactly $10; this gives us the inequality symbol ≤, which makes our complete inequality
1.19x ≤ 10.
To solve this, divide both sides by 1.19:
1.19x/1.19 ≤ 10/1.19
x ≤ 8.4.
Jose won't download a partial song, so we round this down to 8:
x≤8
Answer:
D
Step-by-step explanation:
Review the proof of cos(A - B) = cosAcosB + sinAsinB.
Which of the following complete step 4 of the proof?
1 and 1
2 and 1
(cosAcosB)2(sinAsinB)2 and (cos2(A – B))((sin2(A – B))
(cos2A + sin2A)(cos2B + sin2B) and (cos2(A – B))(sin2(A – B))
Answer:
Option (2)
Step-by-step explanation:
Step 1.
[tex]\sqrt{(\text{cosA-cosB})^2+(\text{sinA-sinB})^2}=\sqrt{(cos(A-B)-1)^2+(sin(A-B)-0)^2}[/tex]
Step 2.
(cosA - cosB)² + (sinA - sinB)² = [cos(A - B) - 1]² + [sin(A - B) - 0]²
Step 3.
cos²A + cos²B - 2cosAcosB + sin²A + sin²B - 2sinAsinB = cos²(A - B) + 1 - 2cos(A - B) + sin²(A - B)
Step 4.
2 - 2cosAcosB - 2sinAsinB = 1 - 2cos(A - B) + 1
Step 5.
cosAcosB + sinAsinB = cos(A - B)
Therefore, Option (2) will be the answer.

What is the question?
Patrick wants to use a gift certificate to buy some songs and videos
from an online media store.
• Songs (s) cost $1 each.
• Videos (v) cost $2.50 each.
• Patrick has a gift certificate for $25 for the store.
Which inequality represents the number of songs and videos Patrick
can buy using only his gift certificate?
Answer:
i think songs it might be correct but im not sure
The inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
Let's suppose the number of songs is 's' and number of videos is 'v'
Total cost for songs = $s
Total cost for videos = $2.50v
Patrick has a gift certificate for $25
Then the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is:
s + 2.50v ≤ 25
Thus, the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

A 2-yard piece of string costs 1.50$. What is the price per foot?
PLEASE HELP
WILL MARK BRAINLIEST
Answer:
0.013333333333333
Step-by-step explanation:
short answer would be 0.013 i think lol
Hi! I believe your answer is $0.25 (twenty-five cents). There are 3 feet in a yard, so in 2 yards, there are 6 feet. If we want to know the cost per foot, we need to divide 1.50 by 6. The quotient is 0.25, or $0.25 per foot. I hope this helps you! Good luck and have a great day/night. ❤️✨

Which of the following slopes would make the "steepest" line?
A.
1/2
B.
3/2
C.
3
D.
4/5
Answer:
D 4/5
Step-by-step explanation:
Answer:
c
Step-by-step explanation:
try giving all of the fractions the same denominator. then, whichever has the biggest numerator is the steepest slope!
the number that 5, 2, and 1 all have in common is 10, so for this question, we'll put all of the fractions over 10.
a. 1/2 = 5/10
b. 3/2 = 15/10
c. 3 = 3/1 = 30/10
d. 4/5 = 8/10
30 is the biggest numerator out of these 4.

Step-by-step explanation:
Tina is considering two cell phone plans and wishes to decide, based on her expected phone usage,
which plan to purchase. Plan A has a monthly fee of $4995. Plan B costs $39.95 per month. Plan A
charges 5¢ per minute after 300 minutes of talk time. Plan B charges 10€ per minute for any talk time
beyond 500 minutes. Which pair of equations could Tina use to decide on the least costly plan for her
usage? Assume Tina always uses more than 500 minutes per month
(a) c = 39.95 + 0,10m - 300)
(b) c = 39.95 + 0.1(m - 500)
c = 49.95 + 0.050m - 500)
C = 49.95 + 0.05(m - 300)
(c) =3995+0.11 - 50
(d) =3995 +0.11 - 500
C = 49.95 + 0.05m - 15
c = 49.95 + 0.05m - 300

Answer:
[tex]\boxed {x = -2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3x + 6 = -3(2x + 4)[/tex]
-Use Distributive Property:
[tex]3x + 6 = -3(2x + 4)[/tex]
[tex]3x + 6 = -6x - 12[/tex]
-Take [tex]6x[/tex] and add it to [tex]3x[/tex]:
[tex]3x + 6 + 6x = -6x + 6x - 12[/tex]
[tex]9x + 6 = -12[/tex]
-Subtract both sides by [tex]6[/tex]:
[tex]9x + 6 - 6 = -12 - 6[/tex]
[tex]9x = -18[/tex]
-Divide both sides by [tex]9[/tex]:
[tex]\frac{9x}{9} = \frac{-18}{9}[/tex]
[tex]\boxed {x = -2}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-2[/tex].

What is the domain of the decreasing function?
Answer:
A function f is called decreasing on an interval if f (a) > f (b) whenever a < b and a, b are in the interval.
Step-by-step explanation:
The domain of the function shown here is the interval [1, 6].On the interval [1, 3], the graph of this function gets higher from left to right; thus we say that this function is increasing on the interval [1, 3].
On the interval [3, 6], the graph of this function gets lower from left to right; thus we say that this function is decreasing on the interval [3, 6].
