Step-by-step explanation:

<em>3x^2 - 5x +3 with x= - 4</em>

<em>3x^2 - 5x +3 with x= - 4substitute the x with -4</em>

3×(-4)^2 - 5× (-4) +3=

=3×(-4)×(-4) +20 +3=

=3×16 +20+3=

=48+23=71

Answer: A
Explanation:
Basically, it points out the value of x, meaning you have to define x as that number so you plug -4 for x.
How I plugged it in: 3(-4)^2-5(-4)+3

For what value of the number k is the following function differentiable at x=2
d1i1m1o1n [39]

Answer:

For f(x) to be differentiable at 2, k = 5.

Step-by-step explanation:

For f(x) to be differentiable at x = 2, f(x) has to be continuous at 2.

For f(x) to be continuous at 2, the limit of f(2 – h) = f(2) = f(2 + h) as h tends to 0.

Now,

f(2 – h) = 2(2 – h) + 1 = 4 – 2h + 1 = 5 – 2h.

As h tends to 0, lim (5 – 2h) = 5

Also

f(2 + h) = 3(2 + h) – 1 = 6 + 3h – 1 = 5 + 3h

As h tends to 0, lim (5 + 3h) = 5.

So, for f(2) to be continuous k = 5

Instructions : Find EX if JX = 17 plz help I don’t understand
Akimi4 [234]

Answer:

51

Step-by-step explanation:

\frac{1}{3}(x) = 17     (One third of the total equals seventeen)

x = 17(3)

x = 51

Centroids create two segments.

The larger makes up \frac{2}{3} of the total.  

The smaller makes up \frac{1}{3} of the total.

If an event has a 55% chance of happening in one trial, how do I determine the chances of it happening more than once in 4 trial
aev [14]

The chances of it happening more than once in 4 trials is 13%

<h3>How to determine the number</h3>

From the information given, we have can deduce that;

Probability of 1 trial = 55%

= 55/ 100

Find the ratio

= 0. 55

We are to find the probability of it happening more than once in 4 different trials

If the probability of it happening in one trial is 555 which equals 0. 55

Then the probability of it happening in 1 in 4 trials is given as;

P(1/4 trials) = 1/ 4 × 55%

P(1/4 trials) = 1/ 4 × 0. 55

Put in decimal form

P(1/4 trials) = 0. 25 × 0. 55

P(1/4 trials) = 0. 138

But we have to know the percentage

= 0. 138 × 100

Multiply the values, we have

= 13. 8 %

Thus, the chances of it happening more than once in 4 trials is 13%

Evaluate f(x) = X(With an exponent of 2) -3x +2, given f(x + 1).
Lana71 [14]

Answer:

f(x + 1) = x² - x

Step-by-step explanation:

f(x) = x² - 3x + 2 when f(x + 1)

f(x + 1) = (x + 1)² - 3(x + 1) + 2

f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2

f(x + 1) = x² - x + 0

f(x + 1) = x² - x

Best of Luck!
