What are my zeros (x^2 - 8x + 1)?
Answers
Answer:
x= 7.87298334621 x=.12701665379
Step-by-step explanation:
This is in standard form so we have to factor this into
x^2-8x + 16 + 1 = 16
(x-4)^2 = 15
(x-4) = [tex]\sqrt{15\\}[/tex]
x-4= ± 3.87298334621
x-4 = 3.87298334621 x-4= -3.87298334621

Answer:
30 I think
Step-by-step explanation:
Area of a triangle is (base×height) ÷2
So that means that to solve this you'd need to do 20 (the base) ×3 (the height). This gives you 60; then you divide it by 2. This gives you 30.

Answer:
x^2+y^2 = 49
Step-by-step explanation:
This is a circle.
The generic equation of a circle is
(x-h)^2+ (y-k)^2 = r^2
where (h,k) is the center and r is the radius
The center of the circle is at the origin which is (0,0)
The radius is 7
(x-0)^2+(y-0)^2 = 7^2
x^2+y^2 = 49
Answer:
[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]
Step-by-step explanation:
we are given a circle
we want to figure out the equation of the circle
remember that,
[tex] \rm \displaystyle E _{c} : (x - {h)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]
(h,k) are the centre of the circle
we can clearly see that the centre of the circle is (0,0) and the redious is 7 units
thus substitute:
[tex] \displaystyle (x - {0)}^{2} + (y - 0{)}^{2} = {7}^{2} [/tex]
further simplification is needed:
[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]

Exterior Angle =
3x + 25°
20°
X + 550
Answers
Answer:
x=65°
Step-by-step explanation:
Since all exterior angles add up to 360°.
⇒(3x+25°) + (20°) + (x+55°) =360°
⇒4x+100°=360° {Add up like terms}
⇒4x=260° {Subtract 100 from both sides}
∴ x=65° {Isolate x (divide both sides by 4)}

Step-by-step explanation:
In order to find the perimeter, you add up all the side lengths which would be expressions in this case
(10c + 10) + (c + 5) + (4d - 9)
add like terms: (10c + c) + (10 + 5 - 9) +4d
= 11c + 6 + 4d
which is the same as 6 + 4d + 11c, I just added them in a different order.

Please help with Volume
Answers
Given:
Length of the cuboid tank = 4 m
Breadth = 2.5 m
Height = 2.4 m
One third of the tank is filled with water.
1 cubic meter = 1000 liters.
To find:
The quantity of the water in the tank.
Solution:
Volume of a cuboid is:
[tex]V=l\times b\times h[/tex]
Where, l is length, b is breadth and h is the height.
The volume of the tank is :
[tex]V=4\times 2.5\times 2.4[/tex]
[tex]V=24[/tex]
Volume of tank is 24 cubic meter.
One third of the tank is filled with water. So, the volume of the water is
[tex]\dfrac{24}{3}=8[/tex]
The volume of water is 8 cubic meters.
We have,
1 cubic meter = 1000 liters.
8 cubic meter = 8000 liters.
Therefore, the quantity of the water in the tank is 8000 liters.

The area of a square playground (in square feet) can be represented by x2 - 30x + 225. How many feet is the perimeter of the playground if x = 25?
Answers
Answer:
40
Step-by-step explanation:
Substitute 25 for x
[tex] {25}^{2} - 30(25) + 225 = 100[/tex]
100 is the area of the square so that means
10 is the side length of each side of the square.
Multiply 4 by 10 to get the perimeter.
[tex]4 \times 10 = 40[/tex]

Answers
Answer:
∠1 = 103°
Step-by-step explanation:
supplementary angle to 136° = 180° - 136° = 44°
∠1 = 180° - 33° - 44° = 103°
Step-by-step explanation:
Let the unnamed angle in the triangle be x.
x + 136 = 180 (Sum of angles on the same straight line)
x = 180 - 136
= 44
Angle 1 + x + 33 = 180 (Sum of angles in a triangle)
Angle 1 + 44 + 33 = 180
Angle 1 + 77 = 180
Angle 1 = 180 - 77
= 103

Answers
Answer:
see explanation
Step-by-step explanation:
The zeros of the graph are x = - 4 and x = 2 , then the factors are
(x + 4)(x - 2) and
y = a(x + 4)(x - 2) ← a is a multiplier
To find a use any other point on the graph and substitute into the equation
Using (0, - 8 ) , then
- 8 = a(4)(- 2) = - 8a ( divide both sides by - 8 )
1 = a
y = (x + 4)(x - 2) = x² + 2x - 8
with b = 2 and c = - 8

Does -6^2 = (-6)^2? Explain your answer.
PLEASE HELP!!!!!!!
Answers
Answer:
No it doesn't
You see when something is in parenthesis () that means it isolated as a whole. When it says (-6)^2 that means Negative six squared. When it says -6^2 that means only the 6 will be squared since they are not parenthesized. So by isolating the two figures both of those numbers together will be squared whereas when they arent isolated only one of them will be squared.
(-6)^2 = -6 x -6 = 36
-6^2= - x 6 x 6= -36
Answer:
-6^2 is same as (-6)^2
Therefore, - 6^2 is - 6×-6 WHICH IS EQUALS TO 36
(-6)^2 = - 6×-6=36
36=36 is the answer.
8. What is the surface area of the pyramid
shown below?
Answers
Answer:
Surface area of square pyramid = 380 m²
Step-by-step explanation:
Given:
Side of square base =10 m
Height of Square pyramid = 14 m
Find:
Surface area of square pyramid
Computation:
Surface area of square pyramid = Surface area of Base + 4[Surface area of triangle]
Surface area of square pyramid = [side x side] + 4[(1/2)(b)(h)]
Surface area of square pyramid = [10 x 10] + 4[(1/2)(10)(14)]
Surface area of square pyramid = 100 + 4[70]
Surface area of square pyramid = 100 + 280
Surface area of square pyramid = 380 m²
