Answer:
[tex]\sqrt{0.5}[/tex]
Step-by-step explanation:
cosx=adj/hyp
adj= [tex]\sqrt{2}[/tex]/2
hyp= r
cos(45)= ([tex]\sqrt{2}[/tex]/2)/r
[tex]\sqrt{2}[/tex]/2 = ([tex]\sqrt{2}[/tex]/2)/r
multiply both sides by r
([tex]\sqrt{2}[/tex]/2)r = [tex]\sqrt{2}[/tex]/2
divide both sides by [tex]\sqrt{2}[/tex]/2
r = 1
pythagorean theorem: [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
a = [tex]\sqrt{2}[/tex]/2
b = y
c = r = 1
[tex](\sqrt{2}/2)^{2}[/tex] + [tex]y^{2}[/tex] = [tex]1^{2}[/tex]
[tex](\sqrt{2}/2)^{2}[/tex] = 2/4 = 0.5
0.5 + [tex]y^{2}[/tex] = 1
subtract 0.5 from 1
[tex]y^{2}[/tex] = 0.5
[tex]\sqrt{y^{2}}[/tex] = [tex]\sqrt{0.5}[/tex]
y = [tex]\sqrt{0.5}[/tex]

What is the surface area of the rectangular prism?
36 cm²
108 cm²
72 cm ²
54 cm²
Answers
Answer:
SA = 108cm² (the 2nd option)
Step-by-step explanation:
h = 4
l = 3
w = 6
SA = 2(lw + lh + wh)
SA = 2((3)(6) + (3)(4) + (6)(4))
SA = 2(18 + 12 + 24)
SA = 2(54)
SA = 108cm²
The surface area of the rectangular prism is 108cm².
Calculation of the surface area of the rectangular prism:Since
height = 4
length = 3
width = 6
So, here the surface area is
SA = 2(lw + lh + wh)
= 2((3)(6) + (3)(4) + (6)(4))
= 2(18 + 12 + 24)
= 2(54)
= 108cm²
hence, The surface area of the rectangular prism is 108cm².

12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3
Answers
Answer:
D) 4/3
Step-by-step explanation:
12. Triangle XYZ is a right triangle. Angle Y is the right angle. If tan Z = 3/4 , then Predict the tan X. A) 4/5 B) 3/4 C) 3/5 D) 4/3
IF tan Z = 3/4
Since m<Y = 90 degrees
Let the opposite side be XY
YZ be the adjacent side
and XZ is the hypotenuse
Given
tan theta = opp/adj
opp = 3 = XY
adj = 4 = YZ
Get the hypotenuse
hyp^2 = 3^2 + 4^2
hyp^2 = 9 + 16
hyp^2 = 25
hyp = √25
hyp = 5
for tanX;
Side opposite to angle X is YZ
Adjacent side = XY = 3
opposite = YZ = 4
Tan X = YZ/XY
Tan X = 4/3
Hence the prediction of Tan X is 4/3

Find f(-) if f(n) = 5n + 6.
Answers
Answer:
f(-1) = 1
Step-by-step explanation:
Are you missing a number after the negative in f(-)?
If so, let me solve for f(-1) so substitute in the n with a -1 so f(-1) = 5(-1) + 6
so f(-1) = -5 + 6 so f(-1) = 1

Step-by-step explanation:
Separate the equation:
c^14/c^6 + c^3/c^6
c^14-6 + c^3/c^6 = c^8 + c^3/c^6
c^8 + c^3-6
c^8 + c^-3
Turn the -3 positive
The final equation = c^8+c^3

A support cable connects the top of a bridge tower to the road below.
The cable is 245.9 feet long and connects to the road at a point 200.7 feet away from the center of the bridge tower.
To the nearest tenth of a foot, how tall is the tower?
Answers
Answer:
the road is 142 ft away from the center of the bridge tower.
Step-by-step explanation:
Since, the bridge tower is standing vertical to the the road, therefore, the angle made by it is a right angle.
Therefore, the triangle made by cable(hypotenuse) and bridge tower (Perpendicular) on road (base) must be a right angled triangle.
Therefore, by Pythagoras theorem, we have
H² = P²+ B²
P²=H²-B²
P²=(245.9)²-(200.7)²
P=√20186.32=142.07

Use 3.14 as an approximation for IT
A 5,024 m
B 2,152 m²
C 1,256 m2
D 628 m²
Answers
Answer: D) 628 m^2
==========================================================
Explanation:
Let's find the area of the full circle first. The radius is 20 meters, since that's half of the diameter 40. So we have r = 20.
We'll use pi = 3.14 as an approximation
A = area of full circle
A = pi*r^2
A = 3.14*20^2
A = 1256
This is the area of a full circle, but we want half of that because we want the area of a semicircle instead. Since your teacher put 1256 for choice C in there, it seems like that is a trick answer.
We'll divide 1256 over 2 to get 1256/2 = 628 square meters as the final answer, which is choice D.
We can abbreviate "square meters" into "m^2".

Is the triangle with sides 9, 12, 14 acute, right or obtuse
Answers
Answer: Acute
Step-by-step explanation: An acute triangle has three angles that each measure less than 90 degrees. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.
Acute triangle, because if you draw out the triangle with the given lengths, each angle will be less than 90, which means it's an acute triangle.

0) Write your answer using integers, proper fractions, and improper fractions in simplest
form.
y = x +
Answers
Answer:
y = 8x + 2
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By this formula, slope of a line passing through (1, 10) and (0, 2) will be,
m = [tex]\frac{10-2}{1-0}[/tex]
m = 8
Equation of the line will be,
y = 8x + b
Since, this line passes through (0, 2),
2 = 8(0) + b
b = 2
Therefore, equation of the line will be,
y = 8x + 2
Answer:
y=3x+2
