Solve P=2 (1+w) for 1.

1 answer:

6 0

P = 2 ( 1 + w ) for 1

1 = 2 ( 1 + w )

Simplify

1 = 2w + 2

Subtract 2 from both sides

2w = -1

Divide by 2

2w = -1
/2 /2

w = -1/2

Write the standard form of the equation of the line through the given point with the given slope. Through (-2,5), slope =-4

AleksandrR [38]

Answer:

$\huge\boxed{4x+y=-3}$

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

(x₁, y₁) - point on a line

m - slope

We have

$m=-4,\ (-2,\ 5)\to x_1=-2,\ y_1=5$

Substitute:

$y-5=-4(x-(-2))\\\\y-5=-4(x+2)$

Convert to the standard form

$Ax+By=C$

$y-5=-4(x+2)$ use the distributive property

$y-5=(-4)(x)+(-4)(2)$

$y-5=-4x-8$ add 5 to both sides

$y-5+5=-4x-8+5$

$y=-4x-3$ add 4x to both sides

$4x+y=-4x+4x-3\\\\4x+y=-3$

Which function is increasing?? :)

exis [7]

Answer:

$\large\boxed{B.\ f(x)=4^x}$

Step-by-step explanation:

Exponential function $f(x)=(a)^x$ is

increasing if $a > 1\to a\in(1,\ \infty)$

decreasing if $0 < a < 1\to a\in(0,\ 1)$

$A.\ f(x)=\left(\dfrac{1}{4}\right)^x\to a=\dfrac{1}{4}\in(0,\ 1)\to\text{decreasing}\\\\B.\ f(x)=4^x\to a=4\in(1,\ \infty)\to\text{increasing}\\\\C.\ f(x)=(0.4)^x\to a=0.4\in(0,\ 1)\to\text{decreasing}\\\\D.\ f(x)=\left(\dfrac{1}{2}\right)^x\to a=\dfrac{1}{2}\in(0,\ 1)\to\text{decreasing}$

How do i solve tan 6° = f/2.3

kondor19780726 [428]

Multiply both sides by 2.3, ( tan 6° x 2.3 = f )
Regroup terms, 2.3 tan 6 = f.
F = 2.3 tan 6°
So the answer is tan 6 = tan 6 I think

Answer:

Close to around 225 times

Step-by-step explanation:
