Help anyone can help me do this question 2,I will mark brainlest.The question is prove that vertices (9,5),(5,-1),(-1,3)of a triangle is an isosceles triangle.​

Answer:

6 seconds

Step-by-step explanation:

h(x)=-(x-2)^2+16

We want h(x) to be 0 ( that is when the ball hits the ground)

0 = -(x-2)^2+16

Subtract 16 from each side

-16  = -(x-2)^2+16-16

-16 = -(x-2)^2

Divide by -1

16 = (x-2)^2

Take the square root of each side

sqrt(16) = sqrt((x-2)^2)

±4 = x-2

Add 2 to each side

2±4 = x-2+2

2±4 =x

2+4 = x   2-4 = x

6 =x  -2 =x

Time cannot be negative so x=6

Answer:

X = 6

Step-by-step explanation:

[tex]here \: c \: is \: the \: \: mid \: point \\ so \: bc = cd \\ 6x - 16 = 4x + 10 \\ x \: terms \: togather \\ 6x - 4x = 10 + 16 \\ 2x = 26 \\ x = \frac{26}{2} \\ x = 13 \\ thank \: you[/tex]

Answer:

x=13

Step-by-step explanation:

BC = CD

6x-16 = 4x+10

Subtract 4x from each side

6x-16-4x = 4x+10-4x

2x-16 = 10

Add 16 to each side

2x-16+16 = 10+26

2x = 26

Divide by 2

2x/2 =26/2

x = 13

Answer:

10 shirts

Step-by-step explanation:

We can use a ratio to solve

50 dollars           125 dollars

-------------------- = -------------------

4 shirts                   x shirts

Using cross products

50 *x = 4 * 125

50x = 500

Divide each side by 50

50x/50 = 500/50

x = 10

Answer:

D. 10

Brainliest, please!

Step-by-step explanation:

50/4 = 125/x

25/2 = 125/x

25 = 250/x

x = 250/25

x = 10

Answer:

AB = 4

Step-by-step explanation:

Since the line is horizontal then its length is the difference of the x- coordinates, that is

AB = | 8 - 4 | = 4 , or

AB = | 4 - 8 | = | - 4 | = 4

Answer:

11,4 > 11 > 9,8 > 1

Step-by-step explanation:

To list the numbers from smallest to largest we need to determine the value of them in same/similar format

11 and 1 is in same format

The approximate value of [tex]\pi ^{2}[/tex] 9.8

the root of [tex]\sqrt{121}[/tex] = 11

the root of  [tex]\sqrt{130}[/tex] is = 11.4 approximately

Now we have them as real numbers we can evaluate

11,4 > 11 > 9,8 > 1 we don't need to write 11 twice but if needed we can write is as:

11,4 > 11 = 11 > 9,8 > 1

Step-by-step explanation:

6 decimal places

0.005011 has six decimal places.

'The place value of a decimal number is recognized according to the position of the dot or decimal point. The first digit to the right of the decimal point indicates the number of tenths and the second digit to the right indicates the number of hundreths.'

According to the given problem,

For the number 0.005011, after the decimal there are numbers up to the sixth place which is that there are six numbers.

For counting decimal places, we need to count the number of digits present to the right of decimal point.

Hence, we can conclude that 0.005011 has 6 decimal places.

Answer:

5

Step-by-step explanation:

The pythagorean theorem

A^2+B^2=C^2

A^2 =12^2

b^2 is what you need to find

C^2= 13^2

so it's

144+B^2=169

-144         -144

B^2=25

square root of 25 is 5 which is the answer

This is a simple problem of ranges, we will find that the ranges for the main floor and the balcony are:

[-6ft, 8ft] or {x ∈ R | -6ft ≤ x ≤ 8ft}

[26ft, 37ft] or {x ∈ R | 26ft ≤ x ≤ 37ft}

respectively.

We know that:

The main floor of the auditorium ranges from 6ft below the stage  to 8 feet above the stage.

The floor of the balcony ranges from 26 to 37 feet above the stage

The ranges relative to the stage will be, in interval notation, the interval that contains the two extremes of the range.

For the main floor, it goes from -6ft to 8ft (the first one is negative because is 6ft below the stage) then this interval will be: [-6ft, 8ft]

While in set-builder notation we want to specify that the variable must be a real number, so we start with: {x ∈ R

And we need to specify that x can go from -6ft to 8ft, then we add the restriction:

{x ∈ R | -6ft ≤ x ≤ 8ft}

Notice that we use a close interval here.

While for the balcony, the minimum is 26ft and the maximum is 37ft, then the interval will be [26ft, 37ft]

For the set-builder notation we will have:

{x ∈ R | 26ft ≤ x ≤ 37ft}

Answer:

It is 6/30

Step-by-step explanation:

This is because when you simplify 6/30 to the lowest form, you get 1/5

Answer:

There are a lot of fraction that can be equal to the values given above. It can be as follows:

 1/5 = 2/10, 3/15, 4/20, 5/25, 6/30, 7/35,8/40

4/7 = 8/14, 12/21, 16/28

6/30 = 12/60, 18/90, 24/120

5/15 = 1/3, 10/30, 20/60

Answer:

1) 43/40

2) 35/6

3) 43/40

4) -5/3

5) 1/6

Step-by-step explanation:

1)  -1 4/5 = -(1*5 +4)/ 5= -9/5

or          1= 5/5  so -1 4/5= -( 5/5+ 4/5)=-9/5

-2 7/8= -(2*8+7)/8=-23/8

=> -9/5 - ( -23/8)= -9/5 + 23/8 = (( -9*8)+(23*5))/40= (-72+ 115)/40

                                                                                =  43/40

2) 4 3/4= (4*4+3)/4= 19/4

-1 1/12= -(1*12+1)/12= -13/12

=> 19/4 - (-13/12)= 19/4 + 13/12 = ((19*3)+13)/12= (57+13)/12= 35/6

3) same like 1)

4) 3 1/3 = (3*3+1)/3= 10/3

=> 10/3 -5= (10- 3*5)/3= (10-15)/3= -5/3

5) -1/3 + 1/2= ((-1*2)+(1*3))/6 = (-2+3)/6= 1/6
