Answer:

7x^(2)-3x+8

Step-by-step explanation:

(5x^(2) - 3x - 2) - (-2x^(2) - +10)

(5x^(2))- (-2x^(2))=7x^(2)

(- 2)-(+10)=+8

7x^(2)-3x+8

The equation c= 0.25n can be used to find the cost (c) of buying n number of apples.
aksik [14]

Answer:

(a) The constant of proportionality is 0.25

(b) 1 apple = $0.25

(c) $3 = 12 apples

Step-by-step explanation:

Given

c= 0.25n

Solving (a): The constant of proportionality;

For an equation:

c=kn

Where

k = constant of proportionality

By comparing: c=kn to c= 0.25n

k = 0.25

Hence, the constant of proportionality is 0.25

Solving (b): What information does k = 0.25 gives.

It represents the unit rate.

<em>So, it means that 1 apple costs $0.25</em>

<em></em>

Solving (c): Number of apples for $3.

This means that c = 3

Substitute 3 for c in c= 0.25n

3 = 0.25n

Make n the subject

n = \frac{3}{0.25}

n = 12

I need help with trigonometry
MrMuchimi

Answer:

In alphabetic order:

x can be found with pythagorean theorem, since triangle ADC is right in D.

x= \sqrt {7^2-2.2^2} \approx 6.6

y and z are 7 times respectively the sine and cosine of angle ACB.

y= 7sin\ 52\° \approx 5.5\\z=7 cos\ 52\° \approx 4.3

Finally, \theta  can be calculated by determining the arc sine (or inverse sine) of the ratio CD over AC

\theta = sin^{-1} (\frac{2.2}7) \approx 18.3\°
