OAB is a triangle
OA = 4a and OB = 5b
M is the midpoint of OB
AN:NB = 2:3
Find OP:PN
Answers
Answer:
5:2
Step-by-step explanation:
ON = OA + AN
AN = 2/5AB
AB = 5b-4a
AN = 2b - 8/5a
ON = 4a - 8/5a +2b
ON = 12/5a+2b
OP = k(12/5a+2b)
OP = OA + AP
AP = x(AM)
AM = 5/2b-4a
OP=4a-4ax+5/2bx
OP=4a-4ax+5/2bx and OP=12/5ak+2bk
Coefficients of A
4-4x=12/5k
k=(20-20x)/12
Coefficients of B
5/2x=2k
k=5/4x
(20-20x)/12 =5/4x
20=35x
x=4/7
k=5/4 * 4/7 = 5/7
OP=k(ON)
OP = 5/7
PN = 2/7
OP:PN = 5:2

Which exponential function has a growth factor of 5?
f(x) = 2(5x)
On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0. It goes through (negative 1, 2) and crosses the y-axis at (0, 0.5).
f(x) = 0.5(2x)
A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is labeled f (x) with entries one-eighth, one-fourth, one-half, 1, 2.

An exponential function can represent growth or decay, and the function that has a growth factor of 5 is f(x) =2(5^x)
How to determine the exponential function?An exponential function is represented as:
f(x) = ab^x
Where b represents the growth factor
From the list of options, we have:
f(x) = 2(5^x) and f(x) = 0.5(2^x)
This means that:
b = 5 for f(x) = 2(5^x)
And b = 0.2 for f(x) = 0.5(2^x)
Hence, the function that has a growth factor of 5 is f(x) =2(5^x)

Answer:
EI = 30
GH = 30
RS = 10
Step-by-step explanation:
Given: PQRST ~ HGFEI
From inspection of the diagram, the corresponding sides are:
RS ~ FE
ST ~ EI
TP ~ IH
QP ~ GH
QR ~ GF
The only pair of sides that both have side lengths are QR and FG. Therefore, we can use these to work out the scale factor of dilation.
QR = 8 and GF = 20
⇒ GF/QR = 20/8 = 2.5
Therefore, HGFEI is an enlargement of PQRST by a scale factor of 2.5
If ST = 12,
⇒ EI = 12 x 2.5 = 30
If QP = 12,
⇒ GH = 12 x 2.5 = 30
If EF = 25,
⇒ RS = 25 / 2.5 = 10
If IH = 15,
⇒ TP = 15 / 2.5 = 6
Answer:
See below ~
Step-by-step explanation:
As they are similar, find the scale factor.
QR ~ GF8 : 202 : 5Finding EI
ST ~ EIST : EI = 2 : 5EI = 5 x 12 / 2 EI = 30Finding GH
QP : GH = 2 : 5GH = 5 x 12 / 2GH = 30Finding RS

Applying the exterior angle theorem, the value of x in the given triangle is: x = 6.
How to Apply the Exterior Angle Theorem?The exterior angle theorem states the relationship between the two remote angles in a triangle and the angle measure of the external angle formed by an extended side outside the triangle.
According to the exterior angle theorem:
The measure of the exterior angle = sum of the measures of the two remote angles in a triangle.
Given the following:
Measure of angle YWX = (2x + 12)°
Measure of angle WXY = (2x + 5)°
Measure of angle XYZ = (7x - 1)°
Therefore:
m∠XYZ = m∠YWX + m∠WXY [exterior angle theorem]
Substitute
(7x - 1)° = (2x + 12)° + (2x + 5)°
Solve for x
7x - 1 = 2x + 12 + 2x + 5
Combine like terms
7x - 1 = 4x + 17
7x - 1 + 1 = 4x + 17 + 1 [addition property of equality]
7x = 4x + 18
7x - 4x = 4x + 18 - 4x [subtraction property of equality]
3x = 18
3x/3 = 18/3 [division property of equality]
x = 6

Martin Office Supplies paid a $6 dividend last year. The dividend is expected to grow at a constant rate of 7 percent over the
next four years. The required rate of return is 20 percent (this will also serve as the discount rate in this problem). Use Appendix
B for an approximate answer but calculate your final answer using the formula and financial calculator methods.
a. Compute the anticipated value of the dividends for the next four years.

Answers
The anticipated value of the dividend in:
Year 1 is $45.86
Year 2 is $49.07.
Year 3 is $52.50.
Year 4 is $56.18.
What is the anticipated value of the dividend?The formula that can be used to determine the value of the dividend is:
Value = dividend paid last year x (1 + growth rate^number of years) / (required return - growth rate)
D1 = ($6 x 1.07) / (20% - 7%) = $45.86
D2 = ($6 x 1.07²) / (20% - 7%) = $49.07
D3 = ($6 x 1.07³) / (20% - 7%) = $52.50
D4 = ($6 x 1.07^4) / (20% - 7%) = $56.18
