3.5 and 3 write a quadratic equation with each pair of values as roots

Mathematics
1 answer:
VLD [36.1K]4 years ago

Hello from MrBillDoesMath!

Answer:  x^2 - 6.5x + 10.5 = 0

Discussion:

If the roots are 3 and 3.5, then the quadratic equation is

(x -3 ) ( x - 3.5) = 0

or

x * (x - 3.5) - 3 (x - 3.5) = 0

or

X^2 - 3.5X - 3X + 3(3.5) = 0

or

x^2 - 6.5x + 10.5 = 0



Thank you,

MrB

24 is 16% of what number
Eva8 [605]
Is/of = %/100 plug the numbers in 24/x = 16/100 then cross multiply then you get 2400 = 16x so you get x by itself so you would have to divide by 16. 2400/16 = 16x/16 the 16 on the x side cancel out so you get x = 150 (I used proportions)

Which equation represents an exponential function that passes through the point (2, 80)?
Lena [83]

The function f(x) = 5(x)⁴, and f(x) = 5(4)ˣ represents the function that passes through the point (2, 80) option second and fourth are correct.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent \rm y = a^x

where a is a constant and a>1

We have; an exponential function that passes through the point (2, 80).

f(x) = 4(x)⁵

Plug (2, 80) in the abovew function:

f(2) = 4(2)⁵ = 128 (false)

f(x) = 5(x)⁴

Plug (2, 80) in the abovew function:

f(2) = 5(2)⁴ = 80 (true)

f(x) = 4(5)ˣ

f(2) = 4(5)² = 100 (false)

f(x) = 5(4)ˣ

f(2) = 5(4)² = 80 (true)

Thus, the function f(x) = 5(x)⁴, and f(x) = 5(4)ˣ represents the function that passes through the point (2, 80) option second and fourth are correct.

Plz Help!!! I need this Asap. Plz give an explanation and no guessing only answer if you know.
borishaifa [10]

Answer:

<h2>50°</h2>

Step-by-step explanation:

AB = AC

So, it is a isosceles triangle.

<B = <C = 65°

Sum of angles of triangle = 180°

< A + < B + <C = 180°

plug the values:

X + 65° + 65° = 180°

Calculate the sum

X + 130° = 180°

Move constant to R.H.S and change its sign

x = 180° - 130°

Calculate the difference

X = 50°

Hope this helps...

Good luck on your assignment...
