8 0

Answer:

D) ( 0,0); minimum

Step-by-step explanation:

The given graph represent the graph of the parent quadratic function $y=x^2$

This graph opens upwards, hence the vertex is the minimum point on the graph of this function.

The graph has its vertex at the origin, (0,0).

The correct option is D.

Roberto has 20 crayons. 12 crayons are red. The rest are blue or yellow. He has two more blue crayons than yellow. How many yell

Licemer1 [7]

20 - 12 = 8

He has 8 blue and yellow crayons altogether.

Yellow = x
Blue = 2 + x

2 + x + x = 8

2 + 2x = 8

Subtract 2 to both sides

2x = 6

Divide 2 to both sides

x = 3.

He has 3 yellow crayons.

seropon [69]

Answer:

4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.

Step-by-step explanation:

<u>Numbers:</u>

4.5,-6,12,-1.1

<u>Let's see which option is correct:</u>

-1.1 is a rational number, 4.5 and -6 are integers, and 12 is a whole number.

4.5 in not an integer, it is incorrect

-1.1 and -6 are rational numbers, 12 is an integer, and 4.5 is a whole number.

4.5 is not a whole number, this is incorrect

4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.

Correct

12 is a rational number, -1.1 and -6 are integers, and 4.5 is a whole number.

-1.1 is not and integer, 4.5 is not a whole number, this is incorrect

For what values of q are the two vectors A = i + j + kq each other and B-iq-23 + 2kg perpendicular to

Sloan [31]

Answer:

The value of q are 0.781,-1.281.

Step-by-step explanation:

Given : Two vectors $A=i+j+kq$ and $B=iq-2j+2kq$ are perpendicular to each other.

To find : The value of q ?

Solution :

When two vectors are perpendicular to each other then their dot product is zero.

i.e. $\vec{A}\cdot \vec{B}=0$

Two vectors $A=i+j+kq$ and $B=iq-2j+2kq$

$(i+j+kq)\cdot (iq-2j+2kq)=0$

$(1)(q)+(1)(-2)+(q)(2q)=0$

$q-2+2q^2=0$

$2q^2+q-2=0$

Using quadratic formula,

$q=\frac{-1\pm\sqrt{1^2-4(2)(-2)}}{2(2)}$

$q=\frac{-1\pm\sqrt{17}}{4}$

$q=\frac{-1+\sqrt{17}}{4},\frac{-1-\sqrt{17}}{4}$

$q=0.781,-1.281$

Therefore, The value of q are 0.781,-1.281.
