Select one:
a.
the two triangles are similar by SAS
b.
the two triangles are not similar
c.
the two triangles are congruent
d.
the two triangles are similar by AA
Since we know that <C is congruent to <E, we can say that: A. the two triangles are similar by SAS.
The properties of similar triangles.In Geometry, two triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.
Ratio = BC/AC = 6/3 = 2.
Ratio = FE/DE = 4/2 = 2.
Thus, the ratio of their corresponding sides are equal in magnitude i.e BC/AC ≡ FE/DE.
Since we know that <C is congruent to <E, we can say that the two triangles are similar by side, angle, side (SAS) criterion.

Find dy/dx by implicit differentiation.
(sin pix + cos piy)^8 = 17
dy/dx =
please help quickly
dy/dx by implicit differentiation is cos(πx)/sin(πy)
How to find dy/dx by implicit differentiation?Since we have the equation
(sin(πx) + cos(πy)⁸ = 17, to find dy/dx, we differentiate implicitly.
So, [(sin(πx) + cos(πy)⁸ = 17]
d[(sin(πx) + cos(πy)⁸]/dx = d17/dx
d[(sin(πx) + cos(πy)⁸]/dx = 0
Let sin(πx) + cos(πy) = u
So, du⁸/dx = 0
du⁸/du × du/dx = 0
Since,
du⁸/du = 8u⁷ and du/dx = d[sin(πx) + cos(πy)]/dx= dsin(πx)/dx + dcos(πy)/dx
= dsin(πx)/dx + (dcos(πy)/dy × dy/dx)
= πcos(πx) - πsin(πy) × dy/dx
So, du⁸/dx = 0
du⁸/du × du/dx = 0
8u⁷ × [ πcos(πx) - πsin(πy) × dy/dx] = 0
8[(sin(πx) + cos(πy)]⁷ × (πcos(πx) - πsin(πy) × dy/dx) = 0
Since 8[(sin(πx) + cos(πy)]⁷ ≠ 0
(πcos(πx) - πsin(πy) × dy/dx) = 0
πcos(πx) = πsin(πy) × dy/dx
dy/dx = πcos(πx)/πsin(πy)
dy/dx = cos(πx)/sin(πy)
So, dy/dx by implicit differentiation is cos(πx)/sin(πy)

∴ [tex]\frac{1}{cos \theta} =\frac{13}{5}[/tex]
[tex]cos \theta = \frac{5}{13}[/tex]
Thus,

Step-by-step explanation:
Area of sectordiameter = 7 cm
r = 7 ÷2 = 3.5 cm
Ф = 45°
[tex]\sf \boxed{\text{\bf Area of sector = $\dfrac{\theta}{360}*\pi r^2$}}[/tex]
[tex]\sf =\dfrac{45}{360}*3.14*3.5*3.5\\\\ = 4.81 \ cm^2[/tex]
Area of the given sectors = 2 *4.81
= 9.62 cm²
Hello!
Let's solve this in step
Let's find the circular region to the left of the center:
[tex]Area = \frac{45}{360}*Area_.formuka_.of_.Circle =\\ Area = \frac{45}{360}*\pi (radius)^2\\ Area = \frac{45}{360} *\pi (3.5)^2\\Area=4.81[/tex]
Now let's find the circular region to the right of the center
⇒ the angle 45° by the vertical angle theorem is equal to the angle
opposite it in the other circular region
⇒ has the same area as the left region
Total Area = 4.81 + 4.81 = 9.62 cm²
Answer: 9.62 square centimeters

Jennifer went to a farm and bought tomatoes
for $2 per pound and garlic for $3 per pound.
If Jennifer spent $72 on tomatoes and garlic,
how many pounds can she buy if she buys
only garlic?
Answer:
24 pounds of garlic
Step-by-step explanation:
if she spends 3$ per pound, you divide 72 by 3. the answer to that is 24, so if she spends 72 dollars on only garlic, she can buy 24 pounds.
Jennifer can buy 24 pounds of garlic
we see here, that if she spends 3$ per pound, you divide 72 by 3.
The answer would be 24, so if she spends 72 dollars on only garlic,
she can buy 24 pounds.

2. Try It #2 The population of a small town increased from 1,442 to 1,868 between 2009 and 2012 . Find the change of population per year if we assume the change was constant from 2009 to 2012 .
Answer:
If it is assumed that the change was constant from 2009 and 2012 , then change of population is 142 .
Step-by-step explanation:
In the question, it is given that the population of a small town increased from 1442 to 1868 between 2009 and 2012 .
It is asked to find the change of population if it is assumed that the change was constant from 2009 and 2012 .
Step 1 of 2
Population in 2012 is given to be 1868 and
Population in 2009 is given to be 1442 .
Duration of year is given by 2012-2009 which is 3 years.
Change in population is given by 1868-1442 which is 426 .
Step 2 of 2
Change in population per year is given by dividing the change in population and the duration of years it took to happen the change.
Hence, change in population per year is
[tex]$\frac{426}{3}=142$[/tex]
Hence, the population was changed by 142 per year from 2009 to 2012 .

Assume that pn and qn are unknown. b. Assume that based on prior studies, about 10% of Californians are left-handed. c. How do the results from parts (a) and (b) change if the entire United States is used instead of California
a. The required sample size when pn and qn are unknown then n = 1844
b. The required sample size when about 10% of Californians are left-handed is n = 664
c. There would have been no effect on parts a and b if entire US has been chosen
According to statement
a. No estimate of proportion is given so we will assume:
{p} = {q} = 0.5
For 99% confidence, z = 2.576
E = 0.03
Hence, Required sample size
n = (0.5)*(0.5)*(2.576/0.03)^2
n = 1844
b. {p} = 0.10
{q} = 1 - {p}
{q} = 1 - 0.10
{q} = 0.90
For 99% confidence, z = 2.576
E = 0.03
Hence, Required sample size n = (0.1)*(0.9)*(2.576/0.03)^2 = 664
c. There would have been no effect on parts a and b if entire US has been chosen because minimum sample size required is not dependent on population size.

x² = 95
x = √95
(x = 9.75)
Answer:
x = [tex]\sqrt{95}[/tex]
Step-by-step explanation:
In this problem, we need to use the Pythagorean theorem.
Pythagorean theorem is a theorem where you can find a side length in a right triangle.
The hypotenuse (The longest side) squared equals the other two side lengths added together after being squared.
In numbers, this will be: (12)^2 = (7)^2 + (x)^2.
144 = 49 + x^2.
95 = x^2
x = [tex]\sqrt{95}[/tex]
We cannot simplify [tex]\sqrt{95}[/tex], so that is the final answer.
