Answer:

The correct answer is A) 2

Step-by-step explanation:

In order to find this, input 1 into the equation for each value of x that you see.

f(x) = x^2 + 3x - 2

f(1) = 1^2 + 3(1) - 2

f(1) = 1 + 3 - 2

f(1) = 2

What is the degree of this polynomial? 5/4y^3+5y^2+y+1

ruslelena [56]

The degree of a polynomial is the highest power anything is raised to. so x+3 is the same as x(^1) + 3
so first degree. 
x^2 +3 is a second degree

Answer:

$d = \sqrt{65}$

Step-by-step explanation:

We need to find the distance between the points (5, 2) and (1, 9). In order to do this, we will use something called the distance formula. The distance formula is written as follows:

$d = \sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2}}$

Now we need to plug in our points which we have given in the form (x, y):

$d = \sqrt{(5-1)^{2}+(2-9)^{2}}$

Next, perform the operation of subtraction inside the parentheses to simplify:

$d = \sqrt{(4)^{2}+(-7)^{2}}$

The exponent is the next step in the order of operations, so square 4 and -7:

$d = \sqrt{16+49}$

Finally, add 16 to 49:

$d = \sqrt{65}$

The square root of 65 cannot be simplified further, but an approximation can be made.

$\sqrt{65}$ ≈ 8.062257748

A scoop of ice cream has 1.5 inch radius. How talk should the cream cone of the same radius be in order to contain all of the ic

MAVERICK [17]

Answer:

The cream cone should be 6 inches.

Step-by-step explanation:

Given:

A scoop of ice cream has 1.5 inch radius.

Now, to find the height of the cream cone.

So, we need to get the volume of scoop by putting formula:

Radius (r) = 1.5 inch.

Using the value π = 3.14.

$Volume=\frac{4}{3} \pi r^3$

$Volume=\frac{4}{3}\times 3.14\times 1.5^3\\\\Volume=\frac{4}{3}\times 3.14\times 3.375\\\\Volume=14.13\ inches^3.$

Thus, the volume of the ice cream scoop is 14.13 cubic inches.

So, to put all of the ice cream inside the cone.

We take the cream cone volume as the scoop volume.

Let the height of cone be $h.$

As, given radius is same.

Now, to get the height of the cream cone we put formula of volume:

$Volume=\pi r^2\frac{h}{3}$

$14.13=3.14 \times (1.5)^2\times \frac{h}{3}\\\\14.13=3.14\times 2.25\times \frac{h}{3}$

Multiplying both sides by 3 we get:

$42.39=3.14\times 2.25\times h\\\\42.39=7.065\times h$

Dividing both sides by 7.065 we get:

$6=h$

$h=6\ inches.$

Hence, the height of the cone = 6 inches.

Therefore, the cream cone should be 6 inches.
