It's the second option, because the signs are facing each other & it's underlined. That's why the circles are shaded in, the inequality means the numbers between -4 & 3 are what is needed. Hope that helps

For f(x)=2x+1 and g(x)=x^2-7, find (f.g)(x)

hram777 [196]

Option C (in the figure) is correct.

Step-by-step explanation:

We need to find (f.g)(x)

Given that $f(x)=2x+1\\g(x)= x^2-7$

Now finding (f.g)(x)

$(f.g)(x)= f(x).g(x)$

$(f.g)(x)= (2x+1)(x^2-7)\\(f.g)(x)=2x(x^2-7)+1(x^2-7)\\(f.g)(x)=2x^3-14x+x^2-7\\(f.g)(x)=2x^3+x^2-14x-7$

So, $(f.g)(x)=2x^3+x^2-14x-7$

Option C (in the figure) is correct.

Probability that people like pizza is p(a) = 0.70. probability that people like burger is p(b) = 0.40. probability that people l

suter [353]

By addition theorem of probability,

P(AUB) = P(A) + P(B) -P(A∩B)
or
P(A or B) = P(A) +P(B) - P(A and B)
P(A or B) = 0.7 + 0.4 - 0.3 = 0.8

Therefore, the probability that randomly selected person likes pizza or burger is 0.8

We can find the length of DE using the Pythagorean Theorem:

prohojiy [21]

What's the difference between A) and C)??
There should be an E) because the correct answer would be in either of these forms:
${DE}^{2} = {(4 - 1)}^{2} + {(1 - 3)}^{2} \: \: or \\ DE = \sqrt{( {3}^{2} + {2}^{2} )} \: \: or \\ {DE}^{2} = {(4 - 1)}^{2} + {(3 - 1)}^{2}$

Statements for parents use the word tight one parent to parent showing symptoms threesome cookies and pizza

Keith_Richards [23]

Cookies = 24

drinks = 8

Apply ratios

Cookies / drinks = 24/8 = 3

drinks /cookies = 8/24 = 1/3

There are 3 times as many cookies as drinks

There are 1/3 times as many drinks as cookies

drinks = 8

pizzas = 2

Drinks/pizzas = 8/2 = 4

Pizzas / drinks = 2/8 = 1/4

There are 4 times as many drinks as pizzas.

There are 1/4 times as many pizzas as drinks.

Cookies = 24

pizzas = 2

Cookies /pizzas = 24/2 = 12

Pizzas / cookies = 2/24 = 1/12

There are 12 times as many cookies as pizzas.

There are 1/12 times as many pizzas as cookies.
