Answer:

36

Step-by-step explanation:

In the above question, we were told that

Given a * b = ba−ba+ab

We are to find (2*3)×(3*2)

Step 1

We simplify each bracket first

a * b = ba−ba+ab

2*3, a = 2, b = 3

2*3 = 3×2 - 3×2 + 2×3

= 6 - 6 + 6

= 6

a * b = ba−ba+ab

3*2, a = 3, b = 2

3*2 = 2×3 - 2×3 + 3×2

= 6 - 6 + 6

= 6

Step 2

(2*3)×(3*2)

= 6 × 6

Let us note that * = × as well. So we would apply the above rule also for our final calculation

a * b = ba−ba+ab

a = 6, b = 6

6 ×6 - 6×6 + 6×6

= 36 - 36 + 36

= 36

The answer is 36

The answer is 36

Consider a circle with a diameter of 5 centimeters. Which equation shows how the relationship between the circumference and the
mrs_skeptik [129]

Answer:

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  \frac{C}{5} ⇒ answer C

Step-by-step explanation:

In any circle there is a constant ratio between the circumference of the circle and its diameter

This constant ratio is called π

∵ The formula of the circumference of a circle is C = π d,

    where d is the diameter of the circle

- Divide both sides by d

∴ \frac{C}{d} = π

- Switch the two sides

∴ π =  \frac{C}{d}

∵ The diameter of the circle is 5 centimeters

∴ π =  \frac{C}{5}

The equation which shows how the relationship between the circumference and the diameter of this circle is equivalent to π is π =  \frac{C}{5}

..vertex: (4, -1)<br> f(3) = -6
s344n2d4d5 [400]

Answer:

\huge\boxed{f(x)=-5(x-4)^2-1=-5x^2+40x-81}

Step-by-step explanation:

The vertex form of an equation of a parabola:

f(x)=a(x-h)^2+k

(h;\ k) - vertex

We have

vertex (4;\ -1)\to h=4;\ k=-1

f(3)=-6

Therefore we have:

f(x)=a(x-4)^2+(-1)=a(x-4)^2-1

Substitute x=3 and f(3)=-6

a(3-4)^2-1=-6\qquad|\text{add 1 to both sides}\\\\a(-1)^2=-6+1\\\\a(1)=-5\\\\a=-5

Finally:

f(x)=-5(x-4)^2-1=-5(x^2-2(x)(4)+4^2)-1\\\\=-5(x^2-8x+16)-1=-5x^2+(-5)(-8x)+(-5)(16)-1\\\\=-5x^2+40x-80-1=-5x^2+40x-81

Please help; I’m hopeless.
Yuliya22 [10]
Well, you have to find 2 of the same number that add together to make that middle number before the c. Then you have to multiply those 2 identical numbers together to find the value of c!——————————————————————So! For number 10, 7+7 is 14, so 7 and 7 are your two identical numbers.——————————————————————Then you have to multiply them to get c! 7•7=49, so 49 is c.——————————————————————I’ll do 11 for you as well, 12+12=24, and 12•12=144, so 144 is c.
