Answer:

1. C

2. B

3. A

4. D

is the correct answer

Answer:

1. 1/3 --> all sides in an equilateral triangle are equal, so the constant of proportionality would be 1/3

2. 10/4*9 = 22.5

3. 8/2 = 4

4. c/g = m

Answer:

-2

Step-by-step explanation:

y=ax+b

Put the numbers into that equation.

-1=1/2*2+b

Simplify:

-1=1+b

-1-1=b

-2=b

Answer:

a) [tex]C(x)[/tex] is increasing in two regions: (i) [tex](+\infty, 8\,s)[/tex] and (ii) [tex](10\,s,+\infty)[/tex].

b) [tex]C(x)[/tex] decreases in [tex](8\,s, 10\,s)[/tex].

Step-by-step explanation:

Let [tex]C(x) = x^{3}-27\cdot x^{2}+240\cdot x +850[/tex], where [tex]x[/tex] is the quantity of insecticide, measured in hundreds of liters, and [tex]C(x)[/tex] is the total manufacturing cost as a function of the quantity of the insecticide, measured in US dollars. A possible approach to determine which regions of [tex]C(x)[/tex] are decreasing and increasing by means of the first derivative and graphing tools. The first derivative of the function is:

[tex]C'(x) = 3\cdot x^{2}-54\cdot x+240[/tex] (1)

Please notice that regions where C(x) is increasing has [tex]C'(x) > 0[/tex], whereas [tex]C'(x) < 0[/tex] when [tex]C(x) < 0[/tex].

We notice that [tex]C(x)[/tex] is increasing in two regions: (i) [tex](+\infty, 8\,s)[/tex] and (ii) [tex](10\,s,+\infty)[/tex]. Besides, [tex]C(x)[/tex] decreases in [tex](8\,s, 10\,s)[/tex].

Answer:

x=7

Step-by-step explanation:

Given that,

Slope of the line, m = -6/7

It contains the point (-5,-8)

To find,

The equation of line.

Solution,

Use the formula as follows :

y = mx+b

Put x = -5 and y = -8

[tex]-8=\dfrac{-6}{7}(-5)+b\\\\b=-8-\dfrac{6}{7}\times 5\\\\b=-12.28\\\\=-\dfrac{86}{7}[/tex]

So, the equation of line is :

[tex]y=\dfrac{-6}{7}x-\dfrac{86}{7}[/tex]

Answer:

43.2 MB

Step-by-step explanation:

The amount that has been downloaded is 17.5% of 247 MB. This is equal to 17.5% [tex]\times[/tex] 247 (in general, "of" always indicates that you should multiply). 17.5% is equal to [tex]17.5/100[/tex], or 0.175.

Therefore, the amount that has been downloaded is 0.175 * 247, which is 43.225 MB. Rounded to the nearest tenth, this is 43.2 MB.

Answer:

$15

Step-by-step explanation:

Good Morning!

If the small toy car costs $3.00, and the large toy car costs 5 times as much as the small one, we can multiply the value of the small car by five to find the value of the large car.

Since five times 3 = 15, the value of the large toy car is $15.00.

Step-by-step explanation:

Answer: 0.1112

Step-by-step explanation:

Let X be a random variable .

Given: A normal population has a mean m=33 and standard deviation s = 9.

The probability that a randomly chosen value will be greater than 44 will be :-

[tex]P(X>44)=P(\dfrac{X-m}{s}>\dfrac{44-33}{9})\\\\=P(Z>\dfrac{11}{9})\\\\=P(Z>1.22)\\\\ =1-P(Z<1.22)\\\\=1-0.8888\\\\=0.1112[/tex]

Hence, the probability that a randomly chosen value will be greater than 44 = 0.1112

A normal population has a mean m=33 and standard deviation s = 9. the probability that a randomly chosen value will be greater than 44 is - 28.774%

Given:

mean m=33

standard deviation s = 9

probability = ?

Solution:

(34-39)/9 = -0.5556

which mean

P(Z<-0.5556) ≈ 0.28774

or 28.774%

Thus, A normal population has a mean m=33 and standard deviation s = 9. the probability that a randomly chosen value will be greater than 44 is - 28.774%

Answer:

∠5 = 71°

∠8 = 109°

Step-by-step explanation:

∠1 = 71°

∠5 = 71°  (the same as ∠1 = 71°) its a corresponding angle

∠8 = 180 - ∠5

∠8 = 180 - 71

∠8 = 109°
