Which statement describes the graph of X = 4?
A) It is paralel to the x-axis.
B) It has a slope of 4.
C) It is parallel to the y-axis.
D) It passes through the point (0,4).
Answer:
the answer is D
Step-by-step explanation:
Because the point of x=4 is passed through the point (0,4).
Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4 find cos(s+t) and cos(s-t)
With Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4, cos(s+t) and cos(s-t) is mathematically given as
cos(s+t)= 0.493
cos(s-t)= 0.97321
What are the values of cos(s+t) and cos(s-t)?Question Parameter(s):
Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4
Generally, the equation for the s and t as functions of the 4 qudrants is mathematically given as
cos(s+t) = cos(s)*cos(t) - sin(s)*sin(t)
Therefore
cos(s+t)= -4/5 * [tex](-\sqrt{21}[/tex]/5) - (-3/5)*(-2/5)
cos(s+t)= 4*[tex]\sqrt{21}/[/tex]25 - 6/25
cos(s+t)= 0.493
In conclusion,
cos(s-t) = cos(s)*cos(t) + sin(s)*sin(t)
cos(s-t)= -4/5 * (-[tex]\sqrt{21}/[/tex]5) + (-3/5)*(-2/5)
cos(s-t)= 4[tex]*\sqrt{21}[/tex]/25 + 6/25
cos(s-t)= 0.97321

Nichole is out shopping and finds a $51.00 bike that was
marked down by 92%.
How much was the item originally?
it was originally "x" or that is 100%. We also know that she found it for 51 bucks, and that those 51 bucks are 100% - 92% = 8% of the original price, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 51&8 \end{array}\implies \cfrac{x}{51}=\cfrac{100}{8}\implies \cfrac{x}{51}=\cfrac{25}{2} \\\\\\ 2x=1275\implies x=\cfrac{1275}{2}\implies x=637.5[/tex]

Homework Section 9.. On a photograph of a triangular piece of land, the lengths of the three sides are 6 cm, 8 cm, and 9 cm, respectively The shortest side of the actual piece of land is 180 m long Find the lengths of the other two sides
Answer:
Step-by-step explanation:
180m = 180 * 100 = 18000 cm
Scale factor = 6 : 18000
= 1 : 3000
Length of other two sides:
8*3000 = 24000 cm = 240 m
9 * 3000 = 27000 cm = 270 m
Find the lengths of the missing sides if side a is opposite angle A, side b is opposite angle B, and side c is the hypotenuse.
c = 18, ∡ A = 45

television has a normal price of 675
in a sale, the price is reduced by 32%
work out the price of the television in the sale
Answer:
$459
Step-by-step explanation:
Given the following question:
32% of 675
To find the answer to this question we need to use the formula to calculate 32% of 675. Then we subtract that answer from our original price which will then give us our answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{32\times 675}{100}[/tex]
[tex]32\times675=21600[/tex]
[tex]21600\div100=216[/tex]
[tex]=216[/tex]
Subtract from the original price:
[tex]675[/tex]
[tex]675-216=459[/tex]
[tex]=459[/tex]
The television after a 32% discount will cost "$459."
Hope this helps.

What is the distance between the points (–4, –8) and (10, –8)?
Answer:
14 units
Step-by-step explanation:
The two given points have the same y-coordinate, so lie on the horizontal line y = -8. The distance between the points will be the difference of their x-coordinates.
distance = 10 -(-4) = 10 +4 = 14
The distance between the points is 14 units.

Find angle C, can someone help me with this please?
Answer:
m∠C = 98°
Step 1: Derive an Equation
To solve this problem, we will use what is called the Exterior Angle Theorem. This states that in a triangle, the measure of an exterior angle is equal to the sum of the measures of its 2 corresponding remote interior angles.
Exterior angle - an angle formed by the extension of 1 side of the triangleRemote interior angles - the 2 angles that don't share a vertex with the exterior angleIn this case, the exterior angle is ∠T (the obtuse one) and the remote interior angles are ∠C and ∠Y. Therefore, m∠T = m∠C + m∠Y.
Substituting the given measures into the equation, we get:
[tex]3x+2+x=130[/tex]
Step 2: Solve the Equation
[tex]3x+2+x=130[/tex]
[tex]4x+2=130[/tex] (Combine like terms)
[tex]4x=128[/tex] (Subtract 2 from both sides to isolate [tex]x[/tex])
[tex]x=32[/tex] (Divide both sides by 4 to get rid of [tex]x[/tex]'s coefficient)
Step 3: Answer the Question
We now know what [tex]x[/tex] is. Therefore, m∠C = [tex]3*32+2=\bf 98 \textdegree[/tex].

Bobby's cat runs x mph. Bobby's dog runs twice as fast as his cat. suppose Bobbys cat and dog were 6 miles apart after 30 min. Write an equation to describe this situation
The equation to describe this situation is that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6
Bobby's cat's speedSince Bobby's cat runs at x mph, its speed is x mph.
Bobby's dog's speedAlso, Bobby's dog runs twice as fast as his cat. So, his dog's speed is v = 2x.
TimeSince they both move a distance in t = 30 min = 30 min × 1 h/60 min = 0.5 h.
Bobby's cat's distanceBobby' cat's distance in 30 mins is d = x × 0.5 h
= 0.5x miles
Bobby's dog's distanceAlso, Bobby's dog covers a distance in 30 min, D = v × 0.5 h
= 2x × 0.5 h
= x miles
The required equationSince Bobbys cat and dog were 6 miles apart after 30 min, we have that
D - d = 6
x - 0.5x = 6
0.5x = 6
So, the equation to describe this situation that Bobby's cat and dog were 6 miles apart after 30 minutes is 0.5x = 6

Find the lengths of AC. Round your answer to the nearest whole number. C a 22.69 B 13 cm A
The triangle ABC is a right triangle
The length of AC is 12.00 cm
How to determine the length of ACFrom the figure, we have the following parameters:
Length AB = 13 cm
Angle A = 22.6 degrees
Represent the length AC with b.
So, we have the following cosine ratio
[tex]\cos(A) = \frac{b}{AB}[/tex]
Substitute known values
[tex]\cos(22.6) = \frac{b}{13}[/tex]
Make b the subject
[tex]b = 13 * \cos(22.6)[/tex]
Evaluate the product
[tex]b = 12.00[/tex]
Hence, the length of AC is 12.00 cm

Note that:
Volume of spherical asteroid = 4πr³/3Finding the volume:
Volume of spherical asteroid = V = 4πr³/3=> V = 4 x π x (8.5 x 10²)³/3=> V = 4 x π x (8.5 x 10²)(8.5 x 10²)(8.5 x 10²)/3=> V = 4 x 3.14 x 8.5 x 10² x 8.5 x 10² x 8.5 x 10²/3=> V = 7713.41 x 10⁶/3=> V ≈ 2571.14 x 10⁶Converting into scientific notation:
