The product of two consecutive numbers is 182

kupik [55]

2 consecutive numbers....x and x + 1

x(x + 1) = 182
x^2 + x = 182
x^2 + x - 182 = 0
(x - 13)(x + 14) = 0

x - 13 = 0
x = 13

x + 14 = 0
x = -14....not this one because it is negative

x + 1 = 13 + 1 = 14

ur 2 numbers are : 13 and 14

HELP! 16x^(2)-40x+6x-15=0 I already factored and this is the extended version, but I don't know where to go from here. Show your

If you're trying to solve for x, you need to use the quadratic formula.
$\frac{-b+/- \sqrt{b^2 - 4(a)(c)} }{2a}$
Plug in the numbers from the standard form of a quadratic equation
(which is $ax^2 + bx + c = 0$ )
$\frac{34+/- \sqrt{34^2 - 4(16)(15)} }{2(16)}$
From here, this solves down to
$\frac{34+/- \sqrt{196}}{32}$
Take the square root of 196, which is 14
$\frac{34+/- 14}{32}$
Now, you can solve for both the + and - variations on the equation.
The solutions to your equation are 1.5 and 5/8 (probably)

sergey [27]

Answer:

In my best opinion I think the answer is E because...........

Step-by-step explanation:

A) 4 x 3 = 12

B) 4 x 4 x 4 = 64

C) 3 x 3 x 3 x 3 = 81

D) 2 x 2 x 2 x 2 x 2 x 2 = 64

and.....

E) NONE OF THE ABOVE! because you asked witch one equals 43 i solved them 4 times but i figured it out. None of the above!!

I hope i got the answer right, have a great day!!

Answer:

50

Step-by-step explanation:

cost function : 35 + 0.2m = 45

35 = fixed cost

0.2 = variable cost

Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments

Variable costs are costs that vary with production

m = miles driven

combine like terms

0.2m = 45 - 35

0.2m = 10

m = 50

Consider the error in using the approximation e−x≈1−x on the interval [−1,1]. (a) reasoning informally, on what interval is this

crimeas [40]

$e^{-x} \approx 1 - x$

is a classic approximation, true for small x.

The next term in the polynomial expansion will be $+kx^2$ where k is a positive number. So our estimate 1-x is definitely an underestimate on both sides of x=0.

Since for negative xs the exponential rises exponentially and the line only linearly, the exponential exceeds the line for all negative x. For positive x, the line quickly goes negative while the exponential is always positive.

So, there's no interval for which our approximation is an overestimate.
