Mo is on a baseball team and hears that a ball thrown at a 45-degree angle from the ground will travel the furthest distance. How should Mo release the ball for the furthest travel distance?
Mo must release this ball approximately halfway between straight-ahead and straight-up because the angle subtended must be 45 degrees with the horizontal axis.
What is distance?Distance can be defined as the amount of ground covered (traveled) by a physical object, regardless of its direction, starting point or ending point.
How should Mo release the ball?In order to achieve the furthest travel distance, Mo must release this ball approximately halfway between straight-ahead and straight-up because the angle subtended must be 45 degrees with the horizontal axis, as shown in the image attached below.

Trapezoid FGHJ is inscribed in P as shown. If FG = 24, JH = 10, and the diameter of P is 26, find the area of the trapezoid. (Hint: draw in auxiliary lines). Round to the nearest tenth if necessary.
Answer:
221
Step-by-step explanation:
If the diameter is 26, the radius is 13 (which is the same as the perpendicular from P to JH)
So, the area is

For each equation, determine whether it represents a direct variation, an inverse variation, or neither.
Find the constant of variation when one exists and write it in simplest form.
The equation 15x + 5y = 0 is a direct variation and the constant of variation is -3 while the equation -5x + 8y = 3 is neither a direct variation nor an inverse variation
How to categorize the type of each equation?As a general rule, we have the following forms of equation:
Direct variation: y =kx
Inverse variation: y = k/x
Where k represents the constant of variation
The equations 15x + 5y = 0 can be rewritten as:
5y = -15x
Divide by 5
y = -3x
The above equation take the form y = kx
This means that k = -3
Hence, the equation 15x + 5y = 0 is a direct variation and the constant of variation is -3
However, the equation -5x + 8y = 3 do not take any of the given forms
Hence, the equation -5x + 8y = 3 is neither a direct variation nor an inverse variation

Which equation has the least steep graph?
O A. y= -1/4x+6
O B. y =-3/4x-9
O C. y = 2x + 1
O D. y=-7x-2
Answer:
y=
[tex] - \frac{1}{4} x + 6[/tex]
Step-by-step explanation:
Standard form of equation of line: y=mx+c
where m = slope
c = y-intercept
Since we know that slope for all equations , we can find the one with the least steep graph.
To find which one is the least steep graph, we find the lowest value in the slope, m. (Ignoring the +/- sign)
In this case, y=
[tex] - \frac{1}{4} x + 6[/tex]
will give the least steep graph as it has the lowest slope value.
each of the two equal angles of an isosceles triangle is half the third angle find the angles of the triangle
Answer:
Two Equal Angles = 45°
Third Angle = 90°
Step-by-step explanation:
Given information
Two equal angles of an isosceles triangle are half the third angle
Set variables
Let x be the angle of the equal angles of the isosceles triangle
Let 2x be the angle of the third angle
Set equations
x + x + 2x = 180 (Triangle angle sum theorem)
Combine like terms
2x + 2x = 180
4x = 180
Divide 4 on both sides
4x / 4 = 180 / 4
[tex]\Large\boxed{x=45^\circ}[/tex]
Substitute the x value into the expression to find the third angle
Third angle = 2x

Find y'' y = 3 cot x/8
If y = 3 cot x/8, the double differentiation of y gives,
y'' = (3/32) (cosec x/8)(cot x/8)
Given value of y is,
y = 3 cot x/8
Differentiation of the above equation will give us the following,
y' = d(3 cot x/8) / dx
y' = 3d(cot x/8) / dx ........... (1)
Now, we know that the differentiation of cot x is -cosec²x
Therefore, d(cot x/8) / dx = -(cosec²x/8)/8
Thus, equation (1) transforms as follows,
y' = -3(cosec²x/8)/8
Taking differentiation of the above equation, we get,
y'' = -3d((cosec²x/8)/ 8dx
y'' = -6d(cosec x/8) / 8dx [Using chain rule] .......... (2)
As we know, the differentiation of cosec x is -(cosec x)(cot x),
d(cosec x/8) / dx = -(cosec x/8)(cot x/8) / 8 [Using chain rule]
Therefore, equation (2) can be written as,
y'' = -(-6(cosec x/8)(cot x/8) / (8×8)
∴ y '' = 3(cosec x/8)(cot x/8) / 32

Answer: x = 50
Concept:
Here, we need to know the idea of alternative interior angles and the angle sum theorem.
Alternative interior angles are angles that are formed inside the two parallel lines, and the values are equal.
The angle sum theorem implies that the sum of interior angles of a triangle is 180°
If you are still confused, please refer to the attachment below or let me know.
Step-by-step explanation:
Given information:
AC ║ DE
∠ABC = 85°
∠A = 135°
Find the value of ∠BAC
∠A + ∠BAC = 180° (Supplementary angle)
(135°) + ∠BAC = 180°
∠BAC = 45°
Find the value of ∠BCA
∠ABC + ∠BAC + ∠BCA = 180° (Angle sum theorem)
(85°) + (45°) + ∠BCA = 180°
∠BCA = 50°
Find the value of x (∠EBC)
∠EBC ≅ ∠BCA (Alternative interior angles)
Since, ∠BCA = 50°
Therefore, ∠EBC = 50°

In the figure, AB = 10, and CE = 11. Find the length of AD. Round your answer to the nearest tenth.
Applying the Chords of a Circle Theorem, the length of AD is: 1.6 units.
What is the Chords of a Circle Theorem?The theorem states that if the radius of a circle is perpendicular to a chord, it divides the chord into two equal halves.
Therefore, we have:
CD = DE = 11/2 = 5.5.

find the price, discount, markup, or cost to store.
Markup=80%
Selling price= $21.60
Cost to store?
Using proportions and the markup concept, it is found that the cost to store is of $12.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The markup price of 80% means that the selling price is of 180% = 1.8 of the cost to store of x. The selling price is of $21.60, hence:
1.8x = 21.60
x = 21.60/1.8
x = $12.

Step-by-step explanation:
6 and 7 was already answered so I'll do 5 and 8.
5. The point the curve crosses the x axis is the x intercept, to find the x intercept of a rational function, we set y=0, and solve for x.
[tex]0 = \frac{x - 4}{x} [/tex]
Set the numerator equal to 0.
[tex]x - 4 = 0[/tex]
[tex]x = 4[/tex]
So the x intercept is (4,0).
Next, to find gradient, we take the derivative of the function.
[tex] \frac{x - 4}{x} [/tex]
We could use product rule, but for simplicity, serperate the function
[tex] \frac{x}{x} - \frac{4}{x} [/tex]
[tex]1 - \frac{4}{x} [/tex]
Next using exponents rules,
[tex]1 - 4 {x}^{ - 1} [/tex]
Now we take the derivative,
Derivative of a constant is zero.
Derivative of a power function,
[tex]n \times x {}^{n - 1} [/tex]
We move the exponent to the front, then we subtract the exponent by 1.
So, we get
[tex]4 {x}^{ - 2} [/tex]
Now, we plug in. 4,
[tex]4(4) {}^{ - 2} [/tex]
[tex]4 \times \frac{1}{16} = \frac{1}{4} [/tex]
The slope or gradient at the x intercept is 1/4
8. The derivative of ax^2+bx, with respect to x is
[tex]2ax + b[/tex]
When x=2, we have a gradient of 8.
[tex]2a(2) + b = 8[/tex]
[tex]4a + b = 8[/tex]
When x=-1, we have a gradient of -10.
[tex]2a( - 1) + b = - 10[/tex]
[tex] - 2a + b = - 10[/tex]
We have two system of equations,
[tex]4a + b = 8[/tex]
[tex] - 2a + b = - 10[/tex]
Let subtract the system to eliminate b.
[tex]6a = 18[/tex]
[tex]a = 3[/tex]
Plug 3 for a, back in to solve for b.
[tex]4(3) + b = 8[/tex]
[tex]12 + b = 8[/tex]
[tex]b = - 4[/tex]
So a is 3
b is -4
