1Determine the vertex of the quadratic function f(x) = (x - 3)^2 +7.
Please give detailed steps!! thank you
Answer:
vertex = (- 3, 7 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = (x - 3)² + 7 ← is in vertex form
with vertex = (3, 7 )

The school ask you to determine the number scale of the drawing if the map length
actual 20 m boundary measurCs 16 cm on the diawing.
(Remember that both units must be the same
9514 1404 393
Answer:
1/125
Step-by-step explanation:
The map scale is usually shown as the ratio of the map distance to real-world distance. Here, that is ...
16 cm : 20 m = 16 cm : 2000 cm = 16 : 2000 = 1 : 125
The map scale is 1/125.

[tex]\huge\boxed{\sf f(4x + 5) = 16x\² + 40x + 25}[/tex]
Step-by-step explanation:
Given that:
f(x) = x²
Put x = 4x + 5
f(4x + 5) = (4x + 5)²
f(4x + 5) = (4x + 5)(4x + 5)
f(4x + 5) = 4x(4x + 5) + 5(4x + 5)
f(4x + 5) = 16x² + 20x + 20x + 25
f(4x + 5) = 16x² + 40x + 25

14. Determine the y-intercept of the quadratic function f(x) = x^2+ 8x - 13
please give detailed steps/walkthrough!! thank you
Answer:
When we talk about Intercept... We refer to the place where the line touches or Crosses a Mentioned axis.
In this question... We needed the y - Intercept
Know This: At the intercept of a mentioned axis...The other axis is zero at that point.
In other words... If we're asked for intercept at x-axis ... The y value at that point is zero and Vice Versa
So To find the y Intercept... the x value at this point is zero(0).
With this in Mind...
substitute x = 0 into the quadratic eqn
f(x) = 0² +8(0) - 13
f(x) = -13
This is Our Y Intercept .
To get the x intercept(if asked)
substitute y = 0 and solve
0 = x² + 8x - 13
This is a quadratic equation
Solving this would get you two value and those values would be your x intercept.
I hope it helps.
Have a great day.

Create an example of a rational value between -8 and -9 and show the work
Answer:
-8.75
Step-by-step explanation:
Rational: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.
A rational number is a number that can be expressed as a fraction with an integer numerator and a positive integer denominator. Two different fractions may correspond to the same rational number. 1/2 = 2/4. Every whole number is a rational number. These can be written as N/1 = N, so they are rational numbers.
Using formula:
[tex]\to \bold{rational\ value =\frac{a+b}{2}}[/tex]
Given:
a=-8
b=-9
Calculating the rational number:
[tex]\to \bold{rational\ number=\frac{-8+(-9)}{2}}[/tex]
[tex]\bold{=\frac{-8-9}{2}}\\\\ \bold{=\frac{-17}{2}}\\\\ \bold{=- 8.5}\\\\[/tex]

15-(4m - 5) = 32 please help me
Answer:
m = -3
Step-by-step explanation:
15 - (4m - 5) = 32 (Given)
15 - 4m + 5 = 32 (Distributed)
20 - 4m = 32 (Added like terms)
20 - 4m - 20 = 32 - 20 (Subtract 20 on both sides)
-4m = 12 (Simplify)
-4m/-4 = 12/-4 (Divide -4 on both sides)
m = -3 (Simplify)

Let:
S=1+2+3+4+5+6+7+8+9+n
We know the answer to the following infinite sum:
S2=1-1+1-1+1-1+1-1+1-1+1-1+1-....= - 1/2
We can therefore solve for this sum:
S3=1-2+3-4+5-6+7-8+9-....
We add them:
S3= 1-2+3-4+5-6+7-8...
S3= +1-2+3-4+5-6+7-8...
________________
2S3= 1-1+1-1+1-1+1-1+1-....
Therefore:
2S3=S2=
