What is the product (x-3)(2x^2-5x + 1)

1 answer:

4 0

F '(x) = 2(3x2 + 5) + 6x(2x - 1) ... + 3), s(x) = x - 4. Use the product rule table. below to get: r'(x) = 20x + 11. s'(x) = 1 ... f'(x) = (x - 4)(20x + 11) - (5x - 2)(2x + 3)/(x - 4)2.First, we will distribute 2x to (x + 5), then we will distribute 3. ... 5x. That is,. multiplying binomials. 6x − x= 5x. Example 2. Multiply (3x − 1)(x + 2). Answer. 3x2 + 5x

Bro this is so simple but I don't know. At the party, jorden shared out all the loonies in his present. Altogether there was 47

katovenus [111]

Answer:

5 lollies are left over

Step-by-step explanation:

Total lollies Jordan has = 47

Number of boys at the party = 6

If the lollies are shared equally,

Number of lollies each boy gets = Total lollies ÷ number of boys

= 47 ÷ 6

= 7 lollies remainder 5

That is,

6 boys × 7 lollies each = 42 lollies

How many lollies were leftover.

Remaining lolly = Total lollies - shared lollies

= 47 - 42

= 5 lollies are left over

Please help! what is an equation of a parabola with x-intercepts at (2,0) and (-7,0) and which passes through the point (1,32)?

grandymaker [24]

Answer:

$f(x)=-4(x-2)(x+7)$

Or, in standard form:

$f(x)=-4x^2-20x+56$

Step-by-step explanation:

We can use the factored form of a quadratic equation:

$f(x)=a(x-p)(x-q)$

Where a is the leading coefficient and p and q are the zeros of the quadratic.

We know that the x-intercepts are at (2, 0) and (-7, 0).

So, let's substitute 2 for p and -7 for q. This yields:

$f(x)=a(x-2)(x+7)$

Now, we need to determine a.

We know that it passes through the point (1, 32). In other words, if we substitute 1 for x, we should get 32 for f(x). Therefore:

$32=a(1-2)(1+7)$

We can now solve for a. First, compute:

$32=a(-1)(8)$

Multiply:

$32=-8a$

Divide both sides by -8:

$a=-4$

So, the value of a is -4.

Therefore, our entire equation is:

$f(x)=-4(x-2)(x+7)$

Notes:

We can expand this into standard form:

$f(x)=-4(x-2)(x+7) \\ f(x)=-4(x^2+5x-14) \\ f(x)=-4x^2-20x+56$

Area 1st rectangle = 10 * 7 = 70 cm^2
length of 2nd rectangle is 2*7 = 14 cm

Area 2nd = 10 * 14 = 140 cm^2

140/70 = 2

The 2nd triangle was twice as big as the 1st. Answer A

The value of y varies directly with x. If x = 4, then y = 32. What is the value of x when y = 128?

pashok25 [27]

Answer:

32/4= 8 (there is a factor of 8 between x and y at all times)

128/8 = 16 (divide y by 8 to find out what x is.

x= 16 when y= 128
