Answer:
30 feet tall
Step-by-step explanation:
Set up a proportion where x is the height of the tree
[tex]\frac{5}{3\frac{1}{3} }[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x:
100 = 3[tex]\frac{1}{3}[/tex]x
30 = x
So, the tree is 30 feet tall

Which is the correct equation for a line that has a slope of 2 and passes through the point (-1, -5). Use the graph below or graph paper if needed.
PLEASE HELP ASAP
A.y = 2x - 5
B.y = 2x + 5
C.y = 2x - 3
D.y = 2x + 3
9514 1404 393
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.

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?
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

Find the area of the composite figure?
Answer:
128
Step-by-step explanation:
Let's start by figuring out the last side of the triangle
we can use the pathagoryous theroem and get
11.9²+x²=16.9²
Solve this and get x=12
Let's now compute the area of the triangle
b*h*.5
12*11.9*.5=71.4
So 71.4 is the area of the triangle
we now need to find the area of the semi circle.
to do this we are going to find the area and then divide it by 2
We know that the length is equal to 12 which means that the radius is 6
so we have
π6²/2
which is 56.55
We add the 71.4+56.55= 127.94 which rounds to 128
Answer:
212.758
Step-by-step explanation:
Find the semi-circle first, the diameter is 16.9 ft.
To find area:
Formula:
pi x radius x radius x 1/2
16.9 ÷ 2 = 8.45 (radius)
22/7 x 8.45 x 8.45 = 224.407 (Circle)
224.407 ÷ 2 = 112.203 (Semi circle)
Find the triangle:
1/2 x base x height or length x base x height
But for now, we will use the first one.
1/2 x 16.9 x 11.9 = 100.555
Now add them up.
100.555 + 112.203 = 212.758

The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of BB?
Answer:
(7, -4)
Step-by-step explanation:
The formula for calculating midpoint is expressed as;
M(X, Y) = (x2+x1)/2, (y1+y2)/2
X = x1+x2/2
Y = y1+y2/2
Given
X = 5, Y = 1, x1 = 3, y1 = 6
Get x2
X = x1+x2/2
5 = 3+x2/2
10 = 3+x2
x2 = 10-3
x2 = 7
Get y2;
Y = y1+y2/2
1 = 6+y2/2
2 = 6+y2
y2 = 2-6
y2 = -4
Hence the coordinate of B is at (7, -4)

please help me will give you brainliest!!
Answer:
yes, no, no, yes
Step-by-step explanation:
Plug in each point into both equations to see which ones fit.
For the first point, (4,1) it works for both equations.
1=-2( 4 ) + 9, 1= -8 + 9, 1=1
4( 4 )+2( 1 )=18, 16 + 2 = 18, 18 = 18
Do it for the rest of the points and plug them in and you get,
no for (5,-3) because -1 does not equal to -3
no for (6,0) because -3 does not equal to 0
(-5,19) is yes because 19=19 and 18=18

What is the probability of getting exactly 1 red?
Answer:
im not sure but this is just a guess (please keep it in mind)
Step-by-step explanation:
4+5= 9 marbles all together
9-1= 8
1 in 8? or 1 in 9
this is becuase we dont know if the one that was taken out randomly first wasnt a red or not but then i could be wrong and the fact if it was red or blue in the first place might not even matter. it really depends.
