Take the answer you get from that and add it to 270. That is your answer.
Answer:
Hence the area of each of the triangles are:
49 cm^2 and 16 cm^2.
Step-by-step explanation:
If the two triangles are similar; the perimeters of the two triangles are in the same ratio as the sides.
We are given that the ratio of the perimeters of two similar triangles is 4:7.
Let a and b denotes perimeter of two triangles.
i.e. here a:b=4:7.
Let A and B denote the area of two triangles.
also we know that for two similar triangles;
Hence,
Also the sum of their areas is 65 cm^2.
i.e.
on putting equation (2) in equation (1) we have:
49(65-B)=16B
49×65-49B=16B
49×65=49B+16B
49×65=65B
B=49 cm^2
Hence by equation (2) we have:
A=65-B
A=65-49=16 cm^2.
Hence the area of each of the triangles are:
49 cm^2 and 16 cm^2.
Answer:
the n(P) of P = {3, 5, 7, 11, 13, 17, 19} is "128".
Step-by-step explanation:
n(P) is the <u>Cardinality</u> of the set P. Its formula is 2^k.
where k = number of elements in the set.
Hope this helps :)
You look at the coefficient of x.
If the parent function is f(x) = 7^x, there is no horizontal stretch.
If the parent function is f(x) = e^x, then your function is
.. f(x) = 7^x = (e^ln(7))^x = e^(ln(7)*x)
and the horizontal compression factor is ln(7) ≈ 1.946. (The stretch factor is 1/1.946 = 0.514.)
Answer:
<h2>
y + 5 = ¹/₆(x - 1)</h2>
Step-by-step explanation:
The slope of a line passing through two given points:
(1, -5) ⇒ x₁ = 1 , y₁ = -5
(-5, -6) ⇒ x₂ = -5 , y₂ = -6
Point-slope form of equation of a line with givem slope m and passing through point (x₁, y₁):
(1, -5) ⇒ x₁ = 1 , y₁ = -5
Therefore:
