Answer:

It is growth and the percentage increase is 46%

Step-by-step explanation:

The general form of an exponential function is;

Y = I(1 + r)^n

where Y is the present value, I is the initial, r is the growth or decay ratio, n is the number of times

To know if an exponential function is growth or decay, we need to know the repeating factor

If repeating factor is greater than 1, we have growth, if otherwise we have decay (less than 1).

As we can see in this case, we have r greater than 2, so what we have is growth

To get the percentage increase since it is growth, we equate;

1.46 = 1 + r

r = 1.46-1

r = 0.46 which is same as 46%

What is the equation of a line with a slope of -2 and passes through the point 3,5¿

dalvyx [7]

Y - y₁ = m(x - x₁)
y - 5 = -2(x - 3)
y - 5 = -2(x) + 2(3)
y - 5 = -2x + 6
+ 5 + 5
y = -2x + 11

A log splitter uses a pump with hydraulic oil to push a piston, attached to which is a chisel. The pump can generate a pressure

faust18 [17]

we are given

The pump can generate a pressure of 2.3x107 pa

so,

$p=2.3*10^7$

a radius of 0.041 m

so,

$r=0.041m$

a stroke lasting 29 s, the piston moves 0.57 m

so,

$h=0.57m$

$t=29s$

Firstly, we will find area

$A=\pi r^2$

$A=\pi (0.041)^2$

$A=0.00528$

now, we can use power formula

$P=\frac{W}{t}$

F=pA

W=Fh

so, W=pAh

we can plug it

$P=\frac{p*A*h}{t}$

now, we can plug values

$P=\frac{2.3*10^7*0.00528*0.57}{29}$

now, we can simplify it

Power=2386.92414 watt.........Answer

Where is water found in... lithosphere, asthenosphere, the mental, or earths core?

erica [24]

Answer:

Water is stored in the following places: The lithosphere (the solid outer crust and upper mantle). In oceanic crust it is stored within the rock structure which it is composed of and in continental crust it is also found in rocks, minerals, and also in clay and as groundwater.

I say the lithosphere.

Step-by-step explanation:

or it can be

But new research suggests a different origin for the oceans: they simply seeped out of the center of the Earth. The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface.
