Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
[tex]\frac{-7}{2(1)} =\frac{-7}{2}[/tex]
Vertex:
[tex]y= (\frac{-7}{2})^{2} +7(\frac{-7}{2}) -8\\y= (\frac{49}{4}) +(\frac{-49}{2}) -8\\y= \frac{49}{4} +\frac{-98}{4} -8\\y=\frac{-49}{4}-8\\y = \frac{-81}{4}[/tex]
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
[tex]y= 0^{2} +7(0) -8\\\\y= -8\\[/tex]

The perimeter of a rectangular window is 264 cm.
If the width of the window is 56 cm, what is its length?
Answers
Answer:
length = 76 cm
Step-by-step explanation:
The perimeter = (2 × width) + (2 × length)
264 = (2×56) + (2 × length)
264 = 112 + (2 × length)
264 - 112 = 2 × length
152 = 2 × length
152/2 = length
76 = length
length = 76 cm

Calculate the work done to stretch an elastic string by 40cm if a force of 10N produces an extension of 4cm in it?
Answers
The work done to stretch an elastic string by 40cm is 20 Joules
Hooke law states that the force (F) applied to a spring is directly proportional to the extension (e).
F ∝ e
F = ke
k is the constant
Given that a force of 10N produces an extension of 4cm, hence:
F = ke
10 = k(4)
k = 2.5 N/cm
For an extension of 40cm, the work done is:
Work done = (1/2)ke²
Work done = (1/2)(2.5 N/cm)(40 cm)² = 2000Ncm = 20 Nm
Work done = 20 Joules
The work done to stretch an elastic string by 40cm is 20 Joules

If x=47 , find the measures of angles 1,2 and 3
Answers
Angle x and 2 are congruent so angle 2 is also 47 degrees.
Angle x and angle 1 are supplementary so angle x and angle 1 adds up to 180 degrees.
180-47=133. Angle 1 is equal to 133.
Angle 1 and angle 3 are congruent as well so angle 3 is also 133 degrees.
Enter the values of x, y, and z. The diagram is not to scale.
Answers
Answer:
x = 86
y = 67
z = 94
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
38 + 56 + x = 180
94 + x = 180 subtract 94 from both sides
x = 86
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle so the value of z:
56 + 38 = 94
again the sum of interior angles in a triangle is equal to 180:
19 + z + y = 180 we found z as 94
19 + 94 + y = 180
113 + y = 180 subtract 113 from both sides
y = 67

separate the solutions
c = ± 12
Solution
c = -12
c = 12
w x and y are three integers w is 2 less than x y is 2 more than x prove that wy+ 4 =x^2
Answers
w + 2 = x
x + 2 = y
Cross multiply
y(w+2) = x(x+2)
wy + 2y = x^2 + 2x
make x the subject of the equation
x = y - 2
substitute this in place of (x) in 2x
wy + 2y = x^2 + 2(y-2)
wy + 2y = x^2 + 2y - 4
wy + 2y - 2y + 4 = x^2
wy + 4 = x^2
