Solve the equation in the interval from 510^\circ510 ∘ 510, degrees to 1050^\circ1050 ∘ 1050, degrees. Your answer should be in degrees. \sin(x)=0sin(x)=0
Answer:
540°, 720° and 900°Step-by-step explanation:
Given equation sin(x) = 0 lying between the interval 510°≤x≤1050°. To find the value of x within this range, we first find the value of from the equation as shown;
sin(x) = 0
taking the arcsin of both sides;
[tex]sin^{-1}(sinx) = sin^{-1} 0\\x = 0^{0}[/tex]
Since x is positive in the first and second quadrant, in the second quadrant, the value of x will be 180°-0° = 180°
Subsequent value of x equivalent to 0° will be addition of 180° to each previous value gotten. The values of x within the range given are as shown
x1 =0°
x2 = 180°-0° = 180(2nd quadrant)
x3 = 180°+180° = 360°
x4 = 360°+180° = 540°
x5 = 540°+180°=720°
x6 = 720°+180° = 900°
x7 = 900°+180° = 1080°
We can see from the values above that the values of x that falls within the given range are 540°, 720° and 900°. This gives the required answers in degrees.

The rectangle below has an area of x^2-7x+10x square meters and a width of x-5x meters. What expression represents the length of the rectangle?
Answer:
The area of a rectangle is:
\sf A=lw
Plug in what we know:
\sf x^2-7x+10=l(x-5)
Factor the left side:
\sf (x-2)(x-5)=l(x-5)
Divide (x - 5) to both sides:
\sf l=\boxed{\sf x-2}
So the length is x - 2 meters.

James delivered 3/8 of the newspaper his route in the first hour and 4/5 of the rest in the second hour. What fraction of the newspaper did James deliver in the second hour?
Answer:
1/2
Step-by-step explanation:
Remaining fraction will be (1-3/8)=5/8
Given that in the second hour he delivered 4/5 of 5/8, then the fraction delivered in the second hour will be:
4/5 of 5/8

This net consists of a square and 4 identical triangles. What is the surface area of the solid this net can form?
144 square inches
184 square inches
224 square inches
264 square inches
Answer: C, 224 inches squared
Step-by-step explanation:
When formed into a solid, the triangles are folded upwards to make a pyramid. You can find the surface area by finding the areas of the individual shapes.
There are four triangles with a height of 10 inches and a base of 8 inches.
There is one square with a side length of 8 inches.
Triangle area formula : A = (b * h) / 2
Square area formula: A = s^2
(10 * 8) / 2 = 40
8 ^ 2 = 64
There are four triangles with area of 40 and one square with area of 64.
40 + 40 + 40 + 40 + 64 = 224 inches squared. The correct answer choice is C.
The surface area of the pyramid is 224 in².
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given net will form a square pyramid, so we will find the surface area of the square pyramid.
Therefore,
The area of the pyramid = side² + 2 × side × height
= 8² + 2 × 8 × 10
= 64 + 160
= 224
Hence the surface area of the pyramid is 224 in².

Mariya's mistake in solving the inequality and plotting the number line is in step 3
How to determine the mistake in the step?The inequality is given as:
[tex]\frac{a}{-13} \le -16[/tex]
Multiply both sides of the inequality by -13
[tex]a \ge 208[/tex]
The above means that the solution to the inequality are numbers greater than or equal to 208.

Using Theorem of Intersecting Secant and Tangent
Applying this theorem in the diagram, we have:

[tex]10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6[/tex]

4 X x= 2 X y
Recall earlier we got: x=11.6
2y=4 X 11.6
2y=46.4
Divide both sides by 2
y=46.4/2=23.2
