Answer:
number of pennies = 54
Step-by-step explanation:
(4,60) ; (6, 65)
Find the slope
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]=\frac{65-60}{6-4}\\\\=\frac{5}{2}[/tex]
m = 5/2 and (4,60)
Equation of the line: y - y1 = m (x -x1)
[tex]y - 60 = \frac{5}{2}(x -4)\\\\y - 60 = \frac{5}{2}x-\frac{5}{2}*4\\\\y- 60 = \frac{5}{2}x-10\\\\y =\frac{5}{2}x-10+60\\\\y=\frac{5}{2}x + 50[/tex]
x-----> determine the number of pennies and y determines the mass of pennies.
Here mass (y -value) is given as 185. We have find the corresponding x-value. So plugin y = 185 in the above equation,
[tex]185 = \frac{5}{2}x+50\\\\185-50=\frac{5}{2}x\\\\135=\frac{5}{2}x\\\\135*\frac{2}{5}=x\\\\27*2=x[/tex]
x = 54

Rewrite each trig function terms of sine and/or cosine. Then use the unit circle to find that,
[tex]\cot(90^{\circ})\cos(45^{\circ}) + \sec(45^{\circ})\\\\\frac{\cos(90^{\circ})}{\sin(90^{\circ})}\cos(45^{\circ}) + \frac{1}{\cos(45^{\circ})}\\\\\frac{0}{1}*\frac{\sqrt{2}}{2} + \frac{1}{(\sqrt{2})/2}\\\\\frac{2}{\sqrt{2}}\\\\[/tex]
Now rationalize the denominator
[tex]\frac{2}{\sqrt{2}}\\\\\frac{2\sqrt{2}}{\sqrt{2}*\sqrt{2}}\\\\\frac{2\sqrt{2}}{\sqrt{2*2}}\\\\\frac{2\sqrt{2}}{\sqrt{4}}\\\\\frac{2\sqrt{2}}{2}\\\\\sqrt{2}[/tex]
Which is the exact value of [tex]\sec(45^{\circ})[/tex]
The portion [tex]\cot(90^{\circ})*\cot(45^{\circ})[/tex] evaluates to 0 and goes away.

Can someone help me out thx
Answers
This is because the two chords are the same length, so they are the same distance away from the center.
We can prove this by drawing the following red segments as shown below. These segments are radii of the circle. After forming the two right triangles, note how we can use the hypotenuse leg (HL) theorem to prove the triangles congruent. So this leads to x = 9 because the corresponding pieces of the triangles must be the same.

Now we have to find the model representing this situation. Difference in number of deer, in the forest.
We can see there is a common ratio between each successive term r = = 0.618
r = = 0.618

A sunflower plant is growing at a constant rate. It was 4cm tall after 1 month and 32 cm tall after
9 months.
a) Express the growth of the plant as a rate of change.
b) Write an equation to show this relationship
Answers
Answer:
a) 3.5 cm / month
b y = 3.5(x-1) + 4, x >= 1
Step-by-step explanation:
the plant grew 32-4 = 28 cm in 9-1 = 8 months.
so, the growth rate is 28 cm / 8 months = 7 cm / 2 months, or (to norm it to a typical 1 unit denominator) 3.5 cm per month.
x = months of growth
y = height of plant
so, considering the "start" of 4 cm after one month, the equation is
y = 3.5(x-1) + 4, x >= 1
since we don't know anything about anything that happened before the first month was over, we cannot validate this equation for anything x<1.

Explain how the Quotient of Powers Property was used to simplify this expression. 5 to the fourth power, over 25 = 52
Answers
The quotient law states that x^m divided by x^n = x^m-n, so I think ;
We first change 25 to 5^ 2
Therefore,
5^4/5^2 = 52
5^4-2 =52
5^2 = 52
Then we change the sum to logarithmic form, which is b^x=y is the same as log (base) b (y)= x
So,
Log (base) 5 (52)= 2
Use the calculator to find the value of the log on your left and the answer is:

Mary is older than John by 5 years .If John is now X years how old is John.
Answers
Based on the relationship between Mary's age and that of John, the representation of Mary's age is (X + 5).
How old is Mary?Your question seems incomplete or not worded well so I'll give a more general response.
Mary is said to be older than John by 5 years. This means that however old John gets, Mary will always be older by 5 years.
If John is X years therefore, Mary's age will simply be:
= John's age + Age difference
= X + 5
For instance, if John is 20 years then Mary would be:
= 20 + 5
= 25 years
