Answer:

try to write the equation from the information below

Step-by-step explanation:

you don't mention how much the car costs and I assume the questions is how many weeks does he have to save to buy the car.

since starts out with $137 dollars you know he's going to add $25 each week.

total saved at the end of one week is 137 + 25

total saved at the end of two weeks is 137 + 50

total saved at the end of three weeks is 137 + 75

can you write the equation for the totaled saved at the end of "W" weeks?

trapecia [35]

<h3><u>3</u><u>6</u> is the answer.</h3>

Step-by-step explanation:

Put value of b as given and using BODMAS rule,

$6(2b - 4)$

$= > 6((2 \times 5)-4)$

$= > 6(10 - 4)$

$= > 6 \times 6$

$= > 36$

Henve, value of of the given expression is $36$

At what point of the curve y = cosh(x does the tangent have slope 2?

Dahasolnce [82]

The hyperbolic cos (cosh) is given by
cosh (x) = (e^x + e^-x) / 2
The slope of a tangent line to a function at a point is given by the derivative of that function at that point.
d/dx [cosh(x)] = d/dx[(e^x + e^-x) / 2] = (e^x - e^-x) / 2 = sinh(x)
Given that the slope is 2, thus
sinh(x) = 2
x = sinh^-1 (2) = 1.444

Therefore, the curve of y = cosh(x) has a slope of 2 at point x = 1.44

Which expression represents the volume, in cubic units, of the shaded part of the sphere? four-thirdsπ(103) four-thirdsπ(43) fou

oee [108]

The volume of the shaded part in cubic units is 4/3π(20)³ - 4/3π(4)³

<h3>Volume of composite object</h3>

The sphere is a a solid 3-dimensional object. THe formula for calculating its volume is expressed as:

V = 4/3πr³

where:

r is the radius of the sphere

<u>For the outer sphere:</u>

V = 4/3π(20)³

<u>For the inner sphere:</u>

V = 4/3π(4)³

The volume of the shaded part in cubic units is 4/3π(20)³ - 4/3π(4)³
