Answer:
9 feet
Step-by-step explanation:
The sine relation applies.
Sin = Opposite/Hypotenuse
sin(30°) = height/(18 ft)
height = (18 ft)sin(30°) = (18 ft)(1/2)
height = 9 ft
The ladder extends 9 feet up the side of the building.
What is the value of the function? f(x)=(−2)^3 (3)^0 (4)^−2
Answer:
-1/2
Step-by-step explanation:
hello :
f(x)=(−2)^3 (3)^0 (4)^−2
(−2)^3 = -8
(3)^0 =1
(4)^−2 1/ (4)^2 =1/16
so : f(x) = (-8)×(1)×(1/16) = -8/16 = -1/2

12x+15=12x (pls solve it step by step)
Answer:
no solutions
Step-by-step explanation:
12x+15=12x
Subtract 12x from each side
12x-12x+15=12x-12x
15 = 0
This is not a true statement so there are no solutions

Answer and Step-by-step explanation:
So, the format you should choose is the second one.
This is what goes in each box:
[4] (p - [6]) = [12]
The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.
Now, we solve for p.
Divide each side by 4.
p - 6 = 3
Now, add 6 to each side.
p = 9.
Each item cost 9 dollars.

Answer:
12x= 180
Step-by-step explanation:
The sum of a triangle always adds up to 180 so,
(4x-1)+ (2x-1) +6 = 180
12x=180
x=15
Answer:
The equation you could use is the 3rd solution. You need to add all of the nubers that have an x after it because you can't add a number that doesn't have x and a number that does have x. So once you add all of those, you add the 10, and keep the subtrction symbol instead of the addition symbol. And like I said before, all triangles are equal to 180.

Given: 2x^2+ 32x + 16 = 0
Step 1: x^2+ 16x +8=0
Step x^2+ 16x = -8
Write numbers in each box to correctly complete the square In Step 3.
Step 3: x^2+ 16x +
Answer:
Step 3: x² + 6x + 64 = -8 + 64
Step-by-step explanation:
At step 3 add 64 on both sides to complete the square.
so x² + 6x = -8
becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.
continuing from there, we get
x² + 6x + 64 = 56
we then use a² + 2ab + b² = (a + b)² on the left side to get
(x + 8)² = 56 (solve the equation for x)
by taking the root on both sides
√(x + 8)² = √56
x + 8 = +- 2√14 (separate the equations
x + 8 = 2√14
x + 8 = -2√14
Solving for x
x = 2√14 - 8 or x = -2√14 - 8

Lupe and her friends spent $20 on snack mix and water. They bought x bags of snack mix and y bottles of water. They bought a total of 11 items. How many bags of snack mix did they buy?
Answer:
6 bags of snack mix
Step-by-step explanation:
x bags of snack mix
y bottles of water
The equations in the question is given as;
20.00 = 2.50x + 1.00y (i)
11 = x + y (ii)
From eqn (ii);
11 - y = x
substitute the value of x in eqn (i);
20.00 = 2.50(11 - y) + 1.00y
20.00 = 27.5 - 2.50y + 1.00y
20.00 - 27.5 = - 1.50 y
- 7.5 = - 1.50 y
y = - 7.5 / (- 1.5) = 5
Since we are interested in the value of x. Substitute the value of y in eqn (ii);
11 = x + 5
x = 11 - 5 = 6

Which expression is equivalent to 2x ^ 2 - 2x + 77 ? (4x + 1.2) + (2x ^ 2 - 6x + 5) (x ^ 2 - 5x + 13) + (x ^ 2 + 3x - 6) (4x ^ 2 - 6x + 11) + (2x ^ 2 - 4x + 4) (5x ^ 2 - 8x + 120) + (- 3x ^ 2 + 10x - 13)
Answer:
None of the answers provided are equivalent
Step-by-step explanation:
To solve it would be best to simplify each of the expressions you have listed by combining like terms all the x^2 terms have been bolded, the x terms italicized, and the constant terms are underlined
(4x + 1.2) + (2x ^ 2 - 6x + 5) = 2x ^ 2 - 6x + 6.2
(x ^ 2 - 5x + 13) + (x ^ 2 + 3x - 6) = 2x^2 -2x +7
(4x ^ 2 - 6x + 11) + (2x ^ 2 - 4x + 4) = 6x^2 -10x +15
(5x ^ 2 - 8x + 120) + (- 3x ^ 2 + 10x - 13) = 2x^2 + 2x + 107

Answer: 4 squared + 2 squared is the least, 5 squared is in the middle, 6 squared - 6 is the greatest
Step-by-step explanation:
least in total=20
middle in total=25
greatest in total=30
Step-by-step explanation:
Here,
1st expression:
[tex] {6}^{2} - 6 = 36 - 6 = 30[/tex]
2nd expression:
[tex] {4}^{2} + {2}^{2} = 16 + 4 = 20[/tex]
3rd expression:
[tex] {5}^{2} = 25[/tex]
Hence, the order from least to greatest is,
20 < 25 < 30
Also,
[tex]( {4}^{2} + {2}^{2} ) < {5}^{2} < ( {6}^{2} - 6) \: \: (ans)[/tex]
