Step-by-step explanation:
7 find the missing length
Answer:
8km
Step-by-step explanation:
it is 8km because it is not that much bigger than 6km
Answer:
C) 8 km
Step-by-step explanation:
x is another leg next to 6.
10 is the hypotenuse.
a^2 + b^2 = c^2
a & b are legs and c is the hypotenuse.
x^2 + 6^2 = 10^2
x^2 + 36 = 100
x^2 = 100 - 36
x^2 = 64
√x^2 = √64
x = 8
P.S It may look just slightly different, but your teacher or the program did not make it up to scale.

For the typing purpose I replaced θ with n in the calculation
[tex]\lim_{n \to \frac{\pi }{4}} \frac{cos n-sin n}{\frac{\pi }{4} } ...limits L'Hopital's Rule\\= \lim_{n \to \frac{\pi }{4}} \frac{-sin n-cos n}{1 } ... plug. in . \frac{\pi }{4} \\= - sin \frac{\pi }{4} - cos \frac{\pi }{4}\\= - \frac{\sqrt{2} }{2} - \frac{\sqrt{2} }{2}\\= \frac{- 2\sqrt{2}}{2} \\= - \sqrt{2}[/tex]
Find the 9th term of the geometric sequence 9, -27, 81, ...
Answer:
59049
Step-by-step explanation:
nine times negative 3 8 times
Answer:
a₉ = 59049
Step-by-step explanation:
The nth term of a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 9 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-27}{9}[/tex] = - 3 , then
a₉ = 9 × [tex](-3)^{8}[/tex] = 9 × 6561 = 59049

Solve and graph the absolute value inequality: 12x +41 > 8.
Answer:
Answer is C
The inequality is x
<−6 or x>2
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
| 2x + 4 | > 8
Case I Case II
2x + 4 > 8 -(2x +4) > 8
-4 -4 -2x - 4 > 8
2x > 4 +4 +4
x > 4/2 -2x > 12
x > 2 -x > 12/2
-x > 6
x < - 6 Multiply by -1 will change the inequality sign.
x > 2 and x< - 6
x > 2 open circle at 2 and shade to the right.
x < -6 open circle at -6 and shade to the left

by factoring out the GCF what is 12r-4?
Answer:
4(3r-1)
Step-by-step explanation:
GCF is the highest number that divides exactly into two or more numbers. In this case, it would be 4 because it's the largest number that both 12 and 4 divide into.

Answer:
1. Enlarge, Shrink
2. Smaller
3. Bigger
Step-by-step explanation:
Dilation is something expanding or shrinking, like how your eyes dilate.
Simply think of the scale factor as what you are multiplying the entire figure by. If you are multiplying it by let's say 2, it would double in size, thus getting larger. If you were to multiply it by 1/2, then it would decrease, or shrink, to half its original size.
Answer:
1: enlarge, shrink
2: smaller
3: bigger

v, the number of visits Mamadou can make to earn his first free movie ticket.
Answer:
Inequality: 7.5v+55≥100
Answer: v≥6
Step-by-step explanation:
Have a good day :)
The inequality for the given situation is 7.5v+55≤100.
Given that, Mamadou receives 55 rewards points just for signing up. He earns 7.5 points for each visit to the movie theater. He needs at least 100 points for a free movie ticket.
What is an inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The number of visits Mamadou can make to earn his first free movie ticket is v.
The inequality for the given situation is 7.5v+55≤100
Subtract 55 on both the sides of inequality.
That is, 7.5v+55-55≤100-55
⇒ 7.5v≤45
⇒ v=45/7.5
⇒ v=6
Therefore, the inequality for the given situation is 7.5v+55≤100.

How do I find the variables here? ;-;
Answer:
y = 116
w = 116
x = 4
Step-by-step explanation:
a // b and t is transversal.
y + 64 = 180 {co-interior angles are supplementary}
y = 180- 64
y = 116
w = y {Alternate interior angles are equal}
w = 116
4x² = 64 {Alternate interior angles are equal}
x² = 64/4
x² = 16
x² = 4²
x = √(4*4)
x = 4
