Answer:
6. 60
7. 24.25
8. 28.00111604 or 28
Step-by-step explanation:
30 +90 =120 180-120=60
Sin A = a/c, so a = cSin A. Also Cos A = b/c, so b = cCos A so Sin30=14/c=28
Cos30=b/28 b=24.25
now 14^2+24.25^2=c^2 which gives 28.00111604 or 28

Answers

Answer:
C. y = 2x - 3
Step-by-step explanation:
The y-intercept (b) can be found from ...
y = mx + b
y - mx = b . . . . . subtract mx
Here, you are given (x, y) = (-1, -5) and slope m = 2.
b = -5 -2(-1) = -5+2 = -3
The correct equation is ...
y = 2x -3 . . . . . matches choice C
_____
On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.

Answer:
i believe it is 73 degrees
Step-by-step explanation:
Answer:
73°
Step-by-step explanation:
All interior angles of a triangle add up to 180°
We are given the angle measure of 17°. Since the triangle is a right triangle, it's safe to assume that the second angle is 90°.
90 + 17 = 107
180 - 107 = 73
The third angle should be 73°. Hope this helps!

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answers
Answer:17
Step-by-step explanation:
trust me its right, no cap
As per compound interest, it would take 17 years for the value of the account to reach $2,550
What is the compound interest?If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 - [tex]e^{rn}[/tex]]
Given, the invested amount (P) = $790.
Rate of interest (r) = 6.9% = 0.069.
Let, the amount is invested for 'n' years.
The value of the amount after 'n' years = $2550.
Now, as per compound interest:
A = P. [tex]e^{rn}[/tex]
⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]
⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)
⇒ [tex]e^{(0.069n)}[/tex] = 3.23
⇒ 0.069n = 1.172
⇒ n = 17

The amount paid for different weights of oranges at a farmer’s market are shown below.
Answers
Answer:
8
Step-by-step explanation:
Well just looking at the problem you can take the first line of data (2 pounds of oranges for $3) and divide that to get how much one orange would be.
So:
$3.00 / 2 = $1.50
So now we have :
1 pound of oranges = $1.50
With this info we can take the $12 on the fourth line and divide it by the price of one pound of oranges ($1.50).
Like so:
$12.00 / $1.50
=
8
We can check this by inputting the 8 on the ?
If we do so we get 8 (8 pounds of oranges) x $1.50 (Price per 1 pound of oranges) = $12.00, which matches up with the $12 price the problem has given us.
Hope this helps!
