These triangles ARE similar! Which reason proves it?

Mathematics
1 answer:
andrew-mc [135]3 years ago

Answer:

SAS

Step-by-step explanation:

From the image attached below, in triangle ABC, AB = 15, AC = 20 while in triangle ADE, AD = 12 and AE = 16

Two triangles are said to be similar if they have the same shape, that is either their corresponding angles are the same or their corresponding sides are proportional.

For both triangle ABC and triangle ADE, they have the same angle which is ∠A. Also:

\frac{AD}{AB}=\frac{12}{15}=\frac{4}{5}

\frac{AE}{AC}=\frac{16}{20}=\frac{4}{5}

Since two sides of triangle ABC are in the same proportion as two sides of triangle ADE and they have the same angle, therefore they are similar based on the SAS  (side-angle-side) similarity

(b) If A(t) is the amount of the investment at time t for the case of continuous compounding, write a differential equation sati
Fantom [35]

Answer:

A'(t) = rA(t)

Step-by-step explanation:

Given

A(t) \to Amount

Required

The differential equation

The equation for the amount is:

A(t) = A_0 * e^{rt}

Where:

A_0 \to initial amount

r \to rate

t \to time

DifferentiateA(t) = A_0 * e^{rt}

A'(t) = A_0 * r * e^{rt}

So, we have:

A'(t) = rA_0 * e^{rt}

From the question, we have: A(t) = A_0 * e^{rt}

So, the equation becomes

A'(t) = rA(t)

Please I really need this fast<br><br> Find the values of a and b in the kite below.
Marina CMI [18]

Answer:

a=5, b=15

Step-by-step explanation:

we know that

The figure MNLO is a Kite

so

LO=NO  and MN=LM

we have

LO=7a-14, NO=b+6

7a-14=b+6 -----> equation A

MN=b, LM=3a

b=3a -----> equation B

Solve the system of equations by substitution

Substitute equation B in equation A and solve for a

7a-14=(3a)+6

7a-3a=6+14

4a=20

a=5

Find the value of b

b=3a ----> b=3(5)=15

therefore

a=5, b=15

What are the exact solutions of x2 = 5x + 2? (1 point)
bazaltina [42]

Answer:

A. x equals 5 plus or minus the square root of thirty-three all over 2

Step-by-step explanation:

Let's move all the terms to one side:

x^2=5x+2

x^2-5x-2=0

Now, we want to use the quadratic formula, which states that for a quadratic equation of the form ax^2+bx+c=0, the roots can be found with the equation: x=\frac{-b+\sqrt{b^2-4ac} }{2a} or x=\frac{-b-\sqrt{b^2-4ac} }{2a}.

Here, a = 1, b = -5, and c = -2, so plug these in:

x=\frac{-(-5)+\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5+\sqrt{25+8} }{2}=\frac{5+\sqrt{33} }{2}

OR

x=\frac{-(-5)-\sqrt{(-5)^2-4(1)(-2)} }{2(1)}=x=\frac{5-\sqrt{25+8} }{2}=\frac{5-\sqrt{33} }{2}

Thus, the answer is A.

Hope this helps!

Which of the following is a perfect square trinomial?
marissa [1.9K]

Answer:

a. x² + 10x + 25

Step-by-step explanation:

because

(x + 5)² = (x + 5)(x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25

so, it is a perfect square of (x + 5).
