Find g(x), where g(x) is the translation 9 units up of f(x)=x2. write your answer in the form m(x+a)2+b, where m, a, and b are integers.

The student's conversion calculation of speed units from kilometers per minute to miles per hour yields a speed of 2.4 miles/hour, so the answer is choice A.

The question is a conversion exercise in speed units from kilometers per minute to miles per hour. We have the following information: 3.2 km in 50 min, and we know that 1 mile is equivalent to 1.6 km and 60 min is equivalent to 1 hour. Thus, the conversion is as follows:

3.2 km ÷ 50 min. = 0.064 km/min.

Converting km/min to mi/hr involves multiplying by 60 (minutes in an hour) and dividing by 1.6 (km in a mile), and we get:

(0.064 km/min x 60 min/hr) ÷ 1.6 km/mi. = 2.4 mi/hr.

Hence, the correct answer is (A) 2.4 miles/hour.

We have been given that the chords AB and CD are equal.

Now, we know that two equal chords subtends equal angle at the center of the circle.

The chord CD subtends and angle CPD at the center and the chord AB subtends an angle APB at the center.

Hence, from above mentioned theorem, we can say that

[tex]\angle CPD = \angle APB[/tex]

Now, we have been given that

[tex]\angle CPD =50 ^{\circ} [/tex]

[tex]\angle APB =x ^{\circ} [/tex]

Hence, we have

[tex]x=50^{\circ}[/tex]

Answer with Step-by-step explanation:

As we can see the venn diagram:

number of bird+fish=6

number of bird+not fish=8

number of fish+not bird=19

and number of not fish and not bird=22

Hence, we get the following table

                        Fish           Not Fish            Total

Bird                6                    8                       14

Not Bird         19                  22                       41

Total               25                 30                       55

                Fish    Not Fish   Total

Bird            6            18           14

Not Bird    19           22          41

Total          25           30         55

The height of cylinder is,

⇒ h = 2.4 inches

We have to given that,

In a cylinder,

Volume = 271.4 inches³

And, Radius = 6 inch

Since, We know that,

Volume of cylinder is,

⇒ V = πr²h

Where, V is volume , r is radius and h is height.

Substitute all the values, we get;

⇒ 271.4 = 3.14 × 6² × h

⇒ 271.4 = 3.14 × 36 × h

⇒ 271.4 = 113.04 × h

⇒ h = 2.4 inches

Thus, The height of cylinder is,

⇒ h = 2.4 inches

Answer:

The new length of the enlarged figure will 18 cm.

Step-by-step explanation:

A scale factor is a number which scales, or multiplies the original figure by some quantity.

In the equation [tex]y = Cx[/tex], C is a scale factor for x. It is called the constant of proportionality or scale factor of y to x.

As the given length is 3 cm, so with a scale factor of 6, the length of the enlarged figure will be [tex]3\times 6=18[/tex] cm

Therefore, the new length of the enlarged figure will 18 cm.

[tex] \displaystyle
|\Omega|=\binom{30}{2}=\dfrac{30!}{2!28!}=\dfrac{29\cdot30}{2}=435\\
|A|=\binom{12}{2}=\dfrac{12!}{2!10!}=\dfrac{11\cdot12}{2}=66\\\\
P(A)=\dfrac{66}{435}=\dfrac{22}{145}\approx15\% [/tex]

Answer:

Option B is correct.

add 4 times the second equation to 3 times the first equation

Step-by-step explanation:

Given the system of equation:

[tex]2x - 4y = 6[/tex]                         ......[1]

[tex]-3x + 3y =12[/tex]                       .....[2]

Multiply equation [1] by 3 we get;

[tex]3(2x-4y) = 3 \cdot 6[/tex]

Using distributive property; [tex]a\cdot (b+c) = a\cdot b+ a\cdot c[/tex]

6x - 12y = 18                                   .......[3]

Multiply equation [2] by 4 we get;

[tex]4(-3x+3y) = 4 \cdot 12[/tex]

Using distributive property we get;

-12x + 12y = 48                                   ......[4]

Add equation [3] and [4] to eliminate y and solve for x;

(6x -12y) + ( -12x +12y ) = 18 + 48

6x - 12y -12x + 12y = 66

Combine like terms;

6x - 12x = 66

or

-6x = 66

Simplify:

x = -11

Therefore, the operation which could be used to eliminate the y-variable and find the value of x is;

add 4 times the second equation to 3 times the first equation.

Answer:

Option B

Step-by-step explanation:

Given is a system of two equations as

[tex]2x − 4y = 6 \\−3x + 3y = 12[/tex]

To solve them using elimination:

Elimination method is the method of making coefficients of one variable numerically equal

IN the given system we have -4 as coefficient for y in I equation and 3 for y in II equation.

To make them numerically equal with opposite signs we can multiply I equation by 3 and II by 4

WE get

[tex]6x-12y =18\\-12x+12y=48[/tex]

Now if we add these two we are able to eliminate y from the system

Adding gives

[tex]-6x=66\\x=-11[/tex]

So option B is right

Answer:

2b - 3 = 5

Step-by-step explanation:

If her brother read b number of books last summer, twice the number of books her brother read

= 2b

three less than twice as many books as her brother read

= 2b - 3

If haley read five books and it is same as three less than twice as many books as her brother last summer, then

2b - 3 = 5
