Write the fraction or mix number and the decimal. 4/10

2 answers:

8 0

So your fraction is 4/10, because it's not over a whole, so it can't be a mixed number.
The decimal is 0.4,because 4/10 has a 4 as the numerator, and the denminator is 10, so 4/10 and 0.4

Glad I could help, and good luck :)

Which function could be represented by the graph on the coordinate plane?

kodGreya [7K]

Answer:

$f(x)=a(x-h)^{2} -k$

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

$f(x)=a(x-h)^{2} +k$

where (h,k) is the vertex of the parabola

The axis of symmetry is equal to

$x=h$

In this problem the parabola open upward

the coefficient a is positive

The coordinates of the vertex will be $(h,-k)$ (the y-coordinate is negative)

the equation will be of the form

$f(x)=a(x-h)^{2} -k$

Which expression represents the product of negative three-fourths x and –8x? negative 35 over 4 x 6x negative 35 over 4 x square

valentinak56 [21]

The expression that represents the product of negative three-fourths x and –8x is 6x^2

<h3>How to determine the equivalent expression?</h3>

The statement is given as:

the product of negative three-fourths x and –8x

Rewrite properly as:

-3x/4 * -8x

Divide 4 and 8 by 4

-3x * -2x

Multiply -3 and -2

6x * x

Multiply x and x

6x^2

Hence, the expression that represents the product of negative three-fourths x and –8x is 6x^2

An engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min. How fast is the volume

zzz [600]

Answer:

Step-by-step explanation:

Given that an engine cylinder 13.7 cm deep is being bored such that the radius increases by 0.13 mm divided by min.

We convert everything in mm for uniformity

We have formula for volume as

$V=\pi r^2 h$

Given that $\frac{dr}{dt} =0.13$

h is constant

$V= 3.14 (r^2) (13.7)\\\frac{dV}{dt} =6.28 (137) r dr/dt\\= 6.28(137)\frac{ (97)}{2} 0.13$

= 6954.67 mm/sec^3
