The key features of the quadratic function are
vertex is (2, 1)Axis of symmetry: x = 2The domain of the function is the set of all real valuesDetermining the key features of the quadratic functionFrom the question, we have the following parameters that can be used in our computation:
y = -x² + 4x - 3
A quadratic function is represented as
y = ax² + bx + c
By comapring the equations, we have
a = -1, b = 4 and c = -3
For the key features
Axis of symmetry: x = -b/2a
So, we have
x = -4/(2 * -1)
x = 2
The domain of the function is the set of all real values
For the vertex, we have
(h, k) = (symmetry, f(symmetry))
So, we have
y = -2² + 4(2) - 3
y = 1
So, the vertex is (2, 1)

A trapezoid has a base of 5cm, a height of 4cm. What is the area?
Answer:
area = 16 cm²
Step-by-step explanation:
area of rectangle = 3x4 = 12
area of triangle = 2x4x0.5 = 4
12 + 4 = 16 cm²
another way is :
1/2(b1+b2)(h) = area
1/2(3+5)(4) = 16 cm²

Find the Volume of the figure. Write the answer in terms of pi.
Answer:
Step-by-step explanation:
[tex]\text{The volume of a cone is}\\ \\ V=\frac{h\pi r^2}{3},\ h=7mi,\ r=2mi\\ \\ V=\frac{7\pi 2^2}{3}\\ \\ V=\frac{28\pi }{3}mi^3[/tex]
Answer:
answer 29.32
Step-by-step explanation:
3.14x2^2 is 12.56 then 12.56x7/3=29.32 because the formula for cone is V=πr2h 3

y varies jointly as x and z. y = 75 when x = 5 and z = 5. Find y when x = 4 and z=6. y =
Answer:
y = 72
Step-by-step explanation:
Joint proportion is given by the expression;
y = kxz
Given the following values;
y = 75, x = 5 and z = 5
To find the constant, k;
75 = k*5*5
75 = 25k
k = 75/25
k = 3
Next, we find the value of y when x = 4 and z= 6
y = kxz
y = 3*4*6
y = 72

One Positive number is five times another number the difference between the two numbers is 172 to find the numbers
Answer:
x= 43, y=215
Step-by-step explanation:
Let one number be x,
Let the other number be y.
x= 5y
x - y= 172
Putting value of x in equation 2.
5y - y = 172
4y = 172
y= 172/4
y= 43
Putting value of y in eq. 1
x= 5(43)
x=215.
