lutik1710 [3]

Answer:

Step-by-step explanation:

Ratio=3:4

so,the pair of adjacent sides are 3x,4x

Pythagorean theorem,

$(3x)^{2}+(4x)^{2}=20^{2}\\9x^{2}+16x^{2}=400\\\\25x^{2}=400\\\\x^{2}=\frac{400}{25}\\\\ x^{2}=16\\\\x=\sqrt{16}\\\\x=4\\\\length=4x=4*4=16cm\\\\breadth=3x=3*4=12cm\\\\Perimeter=2*(l+b)\\\\=2*(16+12)=2*28\\\\=56cm$

Consider that an = 4n-1 represents a sequence. What is the tenth term? A) 361 B) 512 C) 1,024 D) 4,096 E) 262,144

mel-nik [20]

Hello from MrBillDoesMath!

Answer:

Choice E.

Discussion:

Assuming that n >=1, a(n) = 4n -1, then

a(10) = 4(10) - 1 = 39

but that doesn't match any of the answers...... hmm...

BUT

If you meant that a(n) = 4^(n-1), then

a(10) = 4^(10-1) = 4^9 = 262144

which is Choice E.

Thank you,

MrB

What is the slope of 4Y + 8X + 2 = 0?

Leni [432]

4y+8x+2=0
-4y. -4y

8x+2=-4y

Divide by -4 on both sides

-2x-2/4= y

Y= -2x-2/4

The slope is -2
