What is the value of sin Q?
find the gradient of the line segement between the points (0,-6) and (2,-16)
answer = 5
Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m. The larger the value is, the steeper the line. Given m, it is possible to determine the direction of the line that m describes based on its sign and value:
A line is increasing, and goes upwards from left to right when m > 0
A line is decreasing, and goes downwards from left to right when m < 0
A line has a constant slope, and is horizontal when m = 0
A vertical line has an undefined slope, since it would result in a fraction with 0 as the denominator. Refer to the equation provided below.
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m =
y2 - y1
x2 - x1
A new field has a perimeter of 220 m and a width of 62 m. A bag of canola seed will cover 185 m2 of ground. How many bags of canola seed are needed to seed the new field?
52
16
53
17
Answer:
17
Step-by-step explanation:
Assuming the field is a rectangle, the perimeter is found through the equation:
[tex]P = 2l + 2w[/tex]
Since we know the perimeter and width, we can substitute and solve for the length.
[tex](220) = 2l + 2(62)\\220 = 2l + 124\\96 = 2l\\l = 48\\[/tex]
Using the length and width, we can find the area.
[tex]A = lw\\A = (48)(62)\\A = 2976[/tex]
The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.
[tex]n = 2976 / 185\\n = 16.09[/tex]
Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.

Answer:
148.877 cubic meters.
Step-by-step explanation:
To find the volume of a cube, multiply the side length by itself 3 times (x^3).
Like this,
5.3 ⋅ 5.3 ⋅ 5.3 = 148.877
148.877 is the product.
Therefore, 148.877 is the volume of this cube.
A cylindrical well has a radius of 10 feet and a height of 15 feet. What volume of water will it take to fill the well?
Answer:
volume = 4710 ft³
Step-by-step explanation:
base area = πr² = (3.14)(10²) = 314 ft²
volume = base area x height = 314 x 15 = 4710 ft³
Factor the following trinomials. Place each factor in its own blank. You do NOT need to put
parenthesis, just put one binomial (WITHOUT SPACES) into each blank.
X^2+ 13x + 36
Answer:
(x+9)(x+4)
Step-by-step explanation:
We wish to factor x²+13x+36 into the form of (x+p)(x+q) where p+q=13 and pq=36.
Factors of 36: 1, 2, 3, 4, 6, 9, 12. 18, 36
Notice that 9+4=13 as 9*4=36, which satisfies the values of p and q
This means x²+13x+36 can be factored into (x+9)(x+4)

State whether segments of the given lengths can be side of a right angle triangle.
a=7, b=24, and C=25.
Show working to support your answer. *
2 Points
Given:
In a triangle,
[tex]a=7,b=24,c=25[/tex]
To find:
Whether the given segments are the sides of a right triangle or not.
Solution:
In a right triangle the square of largest side is equal to the sum of squares of two smaller side.
[tex]c^2=a^2+b^2[/tex] (Pythagoras theorem)
Three sides are [tex]a=7,b=24,c=25[/tex]. Here, 25 is the largest side.
[tex]25^2=625[/tex]
Now, the sum of squares of two smaller sides is:
[tex](7)^2+(24)^2=49+576[/tex]
[tex](7)^2+(24)^2=625[/tex]
[tex](7)^2+(24)^2=25^2[/tex]
Since the sum of squares of two smaller side is equal to the square of largest side, therefore the given segments are the sides of a right triangle.
Use the following numbers, 4, 30, and 21 to create an equation equal to 1. You may only use each number once. You can use any operation you want to.
Answer:
sqrt(30-21)-sqrt(4)=1
Step-by-step explanation:
I found that sqrt(30-21)-sqrt(4)=1 since sqrt(30-21)=sqrt(9)=3 and sqrt(4)=2 so 3-2=1

What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
we know that,
A secant is a line which intersects a circle at exactly two different points and leaves a chord on joining those two points.
again, we know,
A chord is a line which which terminates on the two different points on the circle.
and, we have,
Radius is the line joining the center to any of the point on the circle.
we know,
Tangent is a line which crosses from the outer periphery of the circle touching at any of its one point.
we get,
Thus the secant in the given diagram is clearly none other than XY.
Hence, The solution is : D. XY, is of the segments below is a secant.
