Answer:

347 is the initial spider population

Step-by-step explanation:

y = ab^x

is the formula for exponential growth and decay

a = the initial value

b is the growth or decay rate

b>1  it is the growth rate  (b-1) is the percent

0<b<1 it is the decay rate (1-b) is the percent

y = 347(1.2)^x

347 is the initial spider population

(1.2-1) = .2 = 20 % growth rate

PLEASE LOOK at the photo and help me on these 2 questions :(!!!!!

Answer:

1) f(g(2)) = 24

2) f(g(-1)) = -4

Step-by-step explanation:

1) GIven f(x) = x²+2x and g(x) = 2x

f(g(x)) = f(2x)

f(2x) = (2x)² + 2(2x)

f(2x) = 4x² + 4x

f(g(x)) = 4x² + 4x

f(g(2)) = 4(2)² + 4(2)

f(g(2)) = 16+8

f(g(2)) = 24

2) f(x) = x+1 and g(x) = 5x

f(g(x)) = f(5x)

f(5x)= 5x + 1

f(g(x)) = 5x + 1

f(g(-1)) = 5(-1) + 1

f(g(-1)) = -5+1

f(g(-1)) = -4

Add. <br> (−2+6x^3−3x^2)+(4x^3−5+x^2)
Gemiola [76]

Answer:

10x^3 - 2x^2 -7

Step-by-step explanation:

To subtract polynomials, you want to subtract the biggest exponent from the first polynomial to the second

so 6x^3 + 4x^3 and that would be 10x^3

then -3x^2 + x^2 and the negative is larger so it would be -2x^2

and finally -2 + -5 and that is -7

hope this helps! :)

A parallelogram has one angle that measures 135 degrees. What are the measures of other three angles in the parallelogram?
geniusboy [140]

Answer:

The measure of other three angles are 135° , 45° and 45°

Step-by-step explanation:

The opposite angles of a parallelogram are equal.

So if we consider a parallelogram ABCD ,

Angle A = Angle C

Angle B = Angle D

If we take angle A = 135° then angle C = 135°

SUM OF INTERIOR ANGLES OF A QUADRILATERAL IS 360°.

A+B+C+D=360°

135°+B+135°+D=360°

270°+B+D=360°

But B=D

So,2B=90°

B=45°

D=45°

So A = C = 135°

A = C = 135° B = D = 45°

A = C = 135° B = D = 45°

Please help me with this and find x!! Thank you, only if you know!
scoray [572]

Answer:

x = 9.8

Step-by-step explanation:

to find x, use pythagorean theorem

a^{2} = c^{2} - b^{2}

a^{2} = 14^{2}  - 10^{2}

a^{2} = 196 - 100

a^{2} = 96

\sqrt{a^2} = \sqrt{96}

a = 9.7979 ⇒ 9.8
