Write the quadratic equation whose roots are -3 and 2 , and whose leading coefficient is 5

Mathematics
1 answer:
KiRa [710]3 years ago
5 0

Step-by-step explanation:

Since, roots are - 3 & 2

Therefore, (x + 3) & (x - 2) would be factors.

Leading coefficient is 5

Hence, required quadratic equation is:

5(x + 3)(x - 2) = 0 \\   \therefore \:  5( {x}^{2}  - 2x + 3x - 6)  = 0\\  \therefore \:  5( {x}^{2}  + x - 6)  = 0\\ \therefore \: 5 {x}^{2}  + 5x - 30  = 0\:  \\ is \: the \: required \:   quadratic \: equation.

If ƒ(x ) = 3x + 1 and ƒ -1 = , then ƒ -1(7) =
Elden [556K]
F(x) = 3x + 1

let f(x) = y

y = 3x + 1

y - 1 = 3x

3x = y - 1

x = (y - 1)/3

From y = f(x),  x = f⁻¹(y) 

<span>x = (y - 1)/3
</span>
 f⁻¹(y)  = (y - 1)/3

f⁻¹(7)  = <span>(7 - 1)/3 = 6/3 = 2

</span>f⁻¹(7)<span> = 2</span>

The heights in inches, of some small trees for sale at a garden store are 62, 62, 59, 61, 59, 70, 59, and 62. What is the median
Nana76 [90]

Answer:

Step-by-step explanation:

the mean height, remember is the average

62+62+59+61+59+70+59+62=494/8=61.75

median is the middle value, so we will write the numbers in order

59,59,59,61,62,62,62,70

we have an even number so we add the middle numbers and divide by 2,

the median=61+62=123/2=61.50  

mode is the number that occurs most often : 62 and 59
