Mathematics
1 answer:
Rom4ik [11]3 years ago

Answer:

I would say that -6 is not included because in order for a function to be included it has to ≤ or ≥. It should be greater than and <u>equal to</u>. 4 is the correct answer because x ≤ 4.

In​ 2010, there were 12.4 million citizens of a certain country diagnosed with diabetes. This number of cases represents an incr
alukav5142 [94]

Answer:

3,131,313

Step-by-step explanation:

Let X represent the number of cases with diabetes in 1973.

An increase of 396% in diabetes cases in 1973 would be;

12.4 million = 396/100 × X

12.4 million = 396X/100

Cross multiply

12.4 million × 100 = 396X

X = [(12.4 million × 100) / 396]

X = 3,131,313

Therefore, the number of diabetes cases in 1973 is 3,131,313 cases

1 point<br> 5) Solve by using the quadratic formula 8x² = 15 - 14x
kykrilka [37]
<h3>I'll teach you how to solve 8x² = 15 - 14x</h3>

----------------------------------------------------

8x² = 15 - 14x

Add 14x to both sides:

8x^2 +14x =15-14x+14x

Simplify:

8x^2 +14x =15

Subtract 15 from both sides:

8x^2+14x-15 = 15-15

SImplify:

8x^2+14x-15 = 0

Solve with the quadratic formula:

x= \frac{-14+ \sqrt{14^2-4*8(1-15)} }{2*8}  = 3/4

x= \frac{-14+ \sqrt{14^2-4*8(1-15)} }{2*8}  = -5/2

The solutions to the quadratic formula are:

x= 3/4, x=-5/2

Your Answer Is x= 3/4, x=-5/2

plz mark me as brainliest :)

use synthetic division to determine which of the following are the real zeroes of the function f(x) = 5x^3 + 8x^2 + x - 2
tester [92]
Always try putting x=1 and x=-1 to see if we can find a zero.
If x=1 we get 5+8+1-2 which is not zero.
If we change the signs of the odd powers of x we get -5+8-1-2 which is zero so x=-1 is a zero and x+1 must therefore be a factor. Now we can use synthetic division to find the quadratic:

-1 | 5 8 1 -2
5 -5 -3 2
————
5 3 -2 | 0 = 5x²+3x-2 = (5x-2)(x+1).

Therefore the real zeroes are -1, 2/5, since -1 is a duplicate zero (because the cubic factorises into (5x-2)(x+1)²).
