Answer:
-36 or 36 ft below the entrance
Step-by-step explanation:
Her starting point is negative since it is below the entrance
-42
Descends 12 feet so subtract 12
-42 -12 = -54
Ascends 18 ft so go up 18 which means add 18
-54 +18 =-36

Answer:
[tex]\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0[/tex]
Step-by-step explanation:
In any right triangle, the following is true:
The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)
The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)
Thus,
[tex]\text{3. }\\\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1},[/tex]
[tex]\text{4. }\tan 68^{\circ}=\frac{GI}{2},\\GI=2\tan68^{\circ}=4.95017370683\approx \boxed{5.0}[/tex]

Answer:
B) 9x² + 6x + 1
Step-by-step explanation:
use the FOIL method:
(3x + 1)(3x + 1)
F: 3x(3x) = 9x²
O: 3x(1) = 3x
I: 3x(1) = 3x
L: 1(1) = 1
combine the 'like terms' in the middle to get 6x
answer: 9x² + 6x + 1
Answer:
the answer is B. 9x^2 + 6x+1
To which graph does the point (2, 4) belong? (1 point) y ≥ x + 3 y ≥ −x + 8 y ≥ 4x − 5 y ≥ −2x + 9
Answer:
y ≥ 4x − 5
Step-by-step explanation:
using the point (2,4)
when x = 2 then y =4
y ≥ 4x − 5
4 ≥ 4(2) - 5
4 ≥ 8 - 5
4 ≥ 3

Which equation represents a function of x that is not linear?
Answer:
y = 4x+3x^2
Step-by-step explanation:
For an equation to be linear, x must have a power of 1
y = 4x+3x^2 has a power of x that is not x ( x^2) so this is not linear ( it is quadratic)
f(x)=3x+4 and g(x) 4x^(2)-x
Find f(-5) and g(-2)

The top of an 18-foot ladder touches the side of a building 14 feet above the ground. Approximately how far from the base of the building should the bottom of the ladder
be placed?
Answer:
Assuming that ladders should be placed at an 75° angle, let's translate it into a slope of 3.732 of a line (looked the value up, was too lazy to calculate it)
the distance from the orign in the picture is your answer, and one side of a triangle formed by the wall, the ground and the ladder

Mira inserts a key into a keyhole to open the door. She turns the key through 156 one-degree angles.
What is the angle measure of the turn that the key made?
9514 1404 393
Answer:
156° or 13π/15 radians
Step-by-step explanation:
156 times 1° is 156°.
In radians, the angle measure is (156°)(π/180°) = 13π/15 radians.
Find the relation independent of y for the following equation
y^2-2y+1 = 0
-y^2+3y+m =0
Answer:
m=−2,y=1
Step-by-step explanation:
Describe how the graph of y= x2 can be transformed to the graph of the given equation. (2 points) y = (x-4)2-8
Answer:
The description is that the function was translated 4 units to the right and 8 units down.
Step-by-step explanation:
Translations:
Translating a function f(x) a units to the right is the same as finding f(x - a).
Translating a function f(x) a units to the left is the same as finding f(x + a).
Translating a function f(x) a units up is the same as finding f(x) + a.
Translating a function f(x) a units down is the same as finding f(x) - a.
y= x² to y = (x-4)²-8
First at the domain, x becomes x - 4, so f(x) becomes f(x - 4), that is, the function was translated 4 units to the right.
Then the function is subtracted by 8, that is, it was translated 8 units down.
The description is that the function was translated 4 units to the right and 8 units down.
Which best describes the data set below?
A. The data is skewed to the right.
B. The data is skewed to the left.
C. The has gap at 2 and a peak at 6.
D. The data is symmetrical.

A cuboid with a volume of 924 cm^3 has dimensions
4 cm, (x + 1) cm and (x + 11) cm.
Find the longest length of the Cuboid.
Answer:
21
Step-by-step explanation:
Volume of a cuboid is given by
V = l*w*h
924 = 4 (x+1) (x+11)
FOIL
924 = 4(x^2 +11x+x+11)
924 = 4(x^2+12x+11)
Divide each side by 4
231 = (x^2+12x+11)
Subtract 231 from each side
0 = x^2 +12x +11-231
0 = x^2 +12x - 220
Factor
0 = (x+22) (x-10)
Using the zero product property
x+22 =0 x-10 =0
x=-22 x=10
We cannot have a negative length
x=10
The side lengths are 4, 10+1, 10+11
4,11,21
The longest is 21

Please show work. What is the volume of the figure?
Answer:
Volume = 288 in.³
Step-by-step explanation:
Volume of the solid = volume of the cube + volume of the square pyramid
V = a³ + ⅓*a²*h
a = 6 in.
h = 12 - 6 = 6 in.
Plug in the values into the volume formula
Volume = 6³ + ⅓*6²*6
Volume = 216 + 72
Volume = 288 in.³
On the refrigerator, MATHCOUNTS is spelled out with 10 magnets, one letter per magnet. Two vowels and three consonants fall off and are put away in a bag. If the Ts are indistinguishable, how many distinct possible collections of letters could be put in the bag?
Answer:
630 distinct possible collections of letters could be put in the bag.
Step-by-step explanation:
Since on the refrigerator, MATHCOUNTS is spelled out with 10 magnets, one letter per magnet, and two vowels and three consonants fall off and are put away in a bag, if the Ts are indistinguishable, to determine how many distinct possible collections of letters could be put in the bag, the following calculation must be performed:
Vowels: 3
(AO, AU, OU)
Consonants: 7
3 x 7 x 6 x 5 = X
3 x 210 = X
630 = X
Therefore, 630 distinct possible collections of letters could be put in the bag.
Answer: 75 distinct possible collections
Step-by-step explanation:
2 vowels = 3C2 = 3
3 vowels = 25 ways
25 * 3 = 75 total ways
Find the circumference of the given circle given a diameter of 9 in
use 3.14
Answer:
28.26
Step-by-step explanation:
Circumference= 2 pi x r
Diameter= 9 (double the radius)
Radius= 4.5
Pi= 3.14
2 x 3.14= 6.28
6.28 x 3.14= 28.26
