2. This is Josh’s solution for the equation :
Is Josh’s solution correct? Explain.
Answer:
x = 7
Step-by-step explanation:
in Josh solution, the steps are correct till
(x-3)² = 16. After this
√(x-3)² = √16
x-3 = 4
x = 4+3 = 7
No, Josh is incorrect the roots of the quadratic equation are 19 & -13.
What is a quadratic equation ?An equation is quadratic in form if it can be written in the form of ax + bx + c = 0, where a, b, and c are constants and x is the variable.
Given that,
The quadratic equation,
x² - 6x - 7 = 0
we can calculate the roots of the equation by using the formula:
x = -b + √(b² - 4ac) / 2a
In the given equation,
a = 1
b = -6
c = -7
x = -(-6) + √((-6)² - 4x1x(-7)) / 2
= (6 + 8)/ 2
x = 7, -1
Hence, Josh's solution is not correct.

PLEASE HELP THIS IS DUE I HAVE BEEN TRYING AND DONT UNDERSTAND IT!!!!
Answer:
Step-by-step explanation:
Moving a coordinate left will subtract from the x coordinate (left 3 means subtract 3 from x coordinate)
Moving a coordinate right will add to the x coordinate (right 3 means add 3 to x coordinate)
Moving a coordinate down will subtract from the y coordinate (down 3 means subtract 3 from y coordinate)
Moving a coordinate up will add to the y coordinate (up 3 means add 3 to y coordinate)
Reflect means flip the sign of the corresponding coordinate
reflect over x axis flip the sign of x coordinate
reflect over y axis flip the sign of y coordinate

3) Dilate K = 3
Answer:
B'''(6, -15), C'''(-3, -12)
Step-by-step explanation:
For point B,
[tex]B(1,\,2) \to B'(1,\,-2) \to B''(2,\,-5) \to B'''(6,\,-15)[/tex]
For point C,
[tex]C(-2,\,1) \to C'(-2,\,-1) \to C''(-1,\,-4) \to C'''(-3,\,-12)[/tex]
Reflecting a point across the x-axis: leave the x-coordinate the same; replace the y-coordinate with its opposite.
<1, -3> These are translations: add 1 to x, subtract 3 from y.
Dilate k=3: multiply both x and y by 3.
Find a polynomial that has the given degree and zeros.
Degree 3 with -1, 3, and -5 as zeros
[tex]x^{3} + {?}x^{2} + {?}x + {?}[/tex]
You can write such a cubic polynomial in terms of its roots using the factor theorem:
(x - (-1)) (x - 3) (x - (-5)) = (x + 1) (x - 3) (x + 5)
Now just expand this:
(x + 1) (x - 3) (x + 5) = x ³ + (1 - 3 + 5) x ² + (-3 + 5 - 15) x - 15
… = x ³ + 3x ² - 13x - 15

Answer:
130.5ft²
Step-by-step explanation:
Hello There!
The figure shown is a composite figure ( so we can't find the area of it using one formula )
That being said we want to break the irregular figure into regular figures in which the area can simply be found using a formula
The figure would be broken in to the following shapes
A rectangle with a width of 4 ft and a length of 9 ft
A rectangle with a width of 8 ft and a length of 9 ft
A triangle with a height of 5 ft and a base of 9 ft
Now that we have broken the irregular figure into regular shapes we want to find the area of each individual shape
For the smaller rectangle:
The area of a rectangle can simply be calculated by multiplying the width and length
So A = 9 * 4
9 * 4 = 36
so the area of the smaller rectangle is 36ft²
For the larger rectangle
Once again the area can simply be found by multiplying the width and length
A = 8 * 9
8 * 9 = 72
so the area of the larger rectangle is 72ft²
For the triangle
To find the area of a triangle we want to use this formula
[tex]A = \frac{bh}{2}[/tex]
where b = base and h = height
We have already identified the base and height so all we have to do is plug in the values into the formula
[tex]A=\frac{5*9}{2} \\5*9=45\\\frac{45}{2} =22.5[/tex]
so the area of the triangle is 22.5ft²
Finally we add the areas of each regular figure
22.5 + 72 + 36 = 130.5
so we can conclude that the area of the composite figure is 130.5ft²

HELP ME PLS!!!
I need help :(
Answer:
Step-by-step explanation:
Remark
I nearly found the length of a chord PQ. Be careful you don't make the same mistake. It is an arc which is part of the circumference.
Equation
Length of arc PQ = angle/360 * 2* pi * r
Givens
Angle = 110
r = 4 in
Solution
Length of arc PQ = 110/360 * 2 * 3.14 * 4
Length of arc PQ = 0.305555 * 6.28 * 4
Length of arc PQ = 7.67555
Length of arc PQ = 7.68

the area of the semi-circle on top is
[tex]\frac{1}{2} \pi r^{2} \\\frac{1}{2} \pi 2^{2} \\\frac{1}{2} \pi 625\\\frac{1}{2} (1963.50)\\= 981.75[/tex]
Total area is 5000+981.75= 5981.75
round up to 5982
Value of X. Please give step by step so I understand
Answer:
The value of x is 15.
Step-by-step explanation:
Since the base is 40 inches long, and the two triangles are congruent - both are right triangles and have sides x and their bases equal - you know that each base of a triangle is 20 inches long. Using the Pythagorean Theorem, you can get that [tex]x^2+20^2=25^2[/tex]. Solve for x by isolating the variable on one side: [tex]x^{2} =25^{2} - 20^{2}[/tex] ⇒ [tex]x^{2} = 625 - 400[/tex] ⇒ [tex]x^{2} = 225[/tex] ⇒ [tex]x^{2} =225[/tex] ⇒ [tex]x=\sqrt{225}[/tex] ⇒ [tex]x=15[/tex] inches.
