Find the difference. (9x^2-2x+7)-(+4x-1)

allochka39001 [22]

Answer: 9x^2 - 6x + 8

Step-by-step explanation:

(9x^2 - 2x + 7) - (4x - 1) Subtract like terms

The term 9x^2 doesn't have any other term so it will stay alone.

-2x - 4x = - 6x

7 - (-1) = 8

Put them together to get 9x^2 - 6x + 8

Given that lim x→1 (5x − 3) = 2, illustrate definition 2 by finding values of δ that correspond to ε = 0.1, ε = 0.05, and ε = 0.

kow [346]

$\displaystyle\lim_{x\to1}(5x-3)=2$

is to say that for any $\varepsilon>0$ , we can find $\delta>0$ such that $0$ implies $|(5x-3)-2|$ .

To that end, we have

$|(5x-3)-2|=|5x-5|=5|x-1|$

which means that if $\varepsilon=0.1$ is given, then we can choose $\delta=\dfrac{0.1}5=0.02$ ; if $\varepsilon=0.05$ , then $\delta=\dfrac{0.05}5=0.01$ ; if $\varepsilon=0.01$ , then $\delta=\dfrac{0.01}5=0.002$ .

Find the explicit formula for -3,-33,-63,-93

bagirrra123 [75]

Answer:

a n = -3+(n-1)-30

Step-by-step explanation:

-3 - 30 = -33

-33 - 30 = -63

-63 - 30 = -93

The common difference here is -30. d = -30

The explicit formula is a n = a1 + (n-1)d

Making coconut cookies. The recipe calls for 420 g of coconut and 120 g of sugar. Only has 252 g of coconut. How much sugar must

geniusboy [140]

Answer: 72 grams.

Step-by-step explanation:

Let be "s" the amount of sugar in grams that must be used for 252 grams of coconut to keep the same ratio of coconut to sugar.

Knowing that in the recipe for the coconut cookies, should be 420 grams of coconut and 120 grams of sugar, and you only have 252 grams of coconut, you can set up this proportion to find "s":

$\frac{420grams}{120grams}=\frac{252grams}{s}$

Now, you need to solve for "s":

$\frac{420grams}{120grams}=\frac{252grams}{s}\\\\s(\frac{420grams}{120grams})=252grams\\\\s=(252grams)(\frac{120grams}{420grams})\\\\s=72grams$
