The number is 12

12 + 4 = 16

4 is a third of 12 and 12 + 4 = 16.

Suppose that the function f is defined. , for all real numbers, as follows.

aivan3 [116]

Answer: The values of......

$f(-5)=\frac{9}{4}\\ \\ f(-2)= -1\\ \\ f(4)=0$

Step-by-step explanation:

Given function is: $\left \{ {{f(x)= \frac{1}{4}x^2 -4, if x\neq -2} \atop {=-1, if x=-2}} \right.$

For $f(-5),$ the value of $x$ is -5, which is not equal to -2.

So, $f(-5)= \frac{1}{4}(-5)^2 -4 = \frac{1}{4}(25)-4 =\frac{25}{4}-4=\frac{25-16}{4}=\frac{9}{4}$

For $f(-2),$ the value of $x$ is -2.

So, $f(-2)= -1$

For $f(4),$ the value of $x$ is 4, which is not equal to -2.

So, $f(4)=\frac{1}{4}(4)^2 -4 =\frac{1}{4}(16)-4 =4-4=0$

X^2 + y^2 - 6x + 8y = 144

Shtirlitz [24]

The diameter of the equation of a circle in the xy-plane as shown is 26 units.

The standard form for finding the equation of a circle is expressed as:

$x^2 + y^2 +2gx + 2fy +C= 0$

For us to get the diameter of the circle, we need to get the radius of the circle first calculated as shown:

$r=\sqrt{g^2+f^2-C}$

Given the equation of the circle expressed as $x^2 + y^2 - 6x + 8y = 144$

Compare with the general formula:

2gx = -6x

g = -6/2

g = -3

Similarly;

2fy = 8y

2f = 8

f = 4

C = -144

Substitute into the formula for calculating the radius;

$r=\sqrt{(-3}^2+4^2-(-144)\\r=\sqrt{9+16+144}\\r=\sqrt{169}\\r=13units$

Get the diameter of the circle

d = 2r

d = 2(13)

d = 26 units

Hence the diameter of the equation of a circle in the xy-plane as shown is 26 units.

What's the answer to this question

Dima020 [189]

If you are trying to ask for the volume of the two rectangular prisms, you can multiply 9m × 10m × 16m and get 1440m^3(meters cubed) for prism A, and multiply 6m × 5m × 3m to get 90m^3

then you add the two together and get

1530m^3 (meters cubed)
