Answer:

D

Step-by-step explanation:

From x- intercepts  it was possible to find the formula of the parabola: x²-1.69=0.

The quadratic function can be represented by a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

From the sum and product of the roots in a quadratic function it is possible to write your respective equation. Since:

This question gives the root since it informs the x- intercepts (1.3,0) and (-1.3,0). Then, the roots are: x1=1.3 and x2= -1.3.

Hence, you should write the equation in factors from the known roots. See: (x-1.3) * (x+1.3)=0. Multiplying the factor, you will have:

x²+1.3x-1.3x-1.69=0

x²-1.69=0

You can check the previous result from :

the sum of the roots (S) will be 1.3-1.3=0.

the product of the roots (P) will be 1.3*(-1.3)=-1.69.

So, the formula of  the parabola is x²-1.69=0. The attached figure shows the x-intercepts and y-intercept  informed.

The time taken by Oliver to complete the work is less than or equal to twice the work done by Karissa.

Option B shows the correct equation of inequality to write the time taken to complete the work.

Inequality can be defined as a relation that makes a non-equal comparison between two numbers or other mathematical expressions.

Given that Oliver completed his project in no more than twice the amount of time it took Karissa to complete her project. Also, the time taken to complete the project is,

Oliver = 4 and one-fourth hours

Karissa = K hours

As per the given condition, the work done by Oliver should not be more than twice the work done by Karissa. It can be equal or less. So we can write this in equation form as,

Oliver [tex]\leq[/tex] 2 Karissa

[tex]4\dfrac {1}{4} \leq 2K[/tex]

Hence Option B shows the correct equation of inequality to write the time taken to complete the work.

Step-by-step explanation:

Answer:

Emily = 49

Asif = 7

Step-by-step explanation:

Let's take the number of marbles given to asif  = x

Then, the marbles got by Emily will be 7 times that of asif 7x

Then,

7x + 1x = 56

8x = 56

x = 56/8

x = 7

So, number of marble asif got = x = 7

And number of marbles Emily got = 7x = 7 * 7 = 49

Answer:

60, 78

Step-by-step explanation:

To find a pattern, try experimenting.

Going from 8 to 18 is + 10

Going from 18 to 30 is + 12

Going from 30 to 44 is + 14

We see that we add 2 more extra than the term before (+10, +12, +14)

So, we just add 2 for the next 2 terms which will be +16 and + 18

which are 44 + 16 = 60

and 60 + 18 = 78

Answer:

im not sure but the pattern im seeing is adding by even numbers i could be wrong but I think the next two numbers are 60, and 78

Step-by-step explanation:

8 + 10 is 18

18+ 12 is 30

30 +14 is 44

so i did

44+16 and got 60

and 60 + 18 is 78.

the area of the shaded region : (9x3)+(12x3) = 27+36=63

The area of the shaded region is equal to the subtraction of the total area to the area of the two small squares and one big square. Then the area of the shaded region is 63 square units.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

All of the quadrilaterals in the shape below are squares.

Then the area of the shaded region will be

The area of the shaded region is equal to the subtraction of the total area to the area of the two small squares and one big square.

Area = 15 × 15 - 3 × 3 - 3 × 3 - 12 × 12

Area = 225 - 9 - 9 - 144

Area = 225 - 162

Area = 63

Answer:

it does not exist

Step-by-step explanation:

if it is a geometric sequence, there must be a common ratio or multiplication factor between neighboring terms :

102 × r = 112.2

r = 112.2/102 = 1.1

is 112.2 × 1.1 = 123.42 ?

yes.

so, it is a geometric sequence with the common ratio of 1.1.

the problem is now : the ratio is > 1.

that means the sequence tends are growing, and growing, and the sum is therefore rather "exploding" than converging.

for the sum to converge to a specific number the individual terms need to get smaller and smaller in absolute numbers.

with r > 1 this is impossible, so there is no sum for this sequence (with n going to infinity, so does the sum, and as "infinity" is not a value per se, the sum does not exist).

Answer

The probability of this occurring is 1/7

Step-by-step explanation:

Okay, here is a probability question.

From the question, we can identify the following;

Total number of socks = 2 + 4 + 2 = 8 socks

Since we are not given the order in which the socks was worn, we can assume any order.

Let’s say the right leg socks was worn first.

From the question, the socks on the right leg is a brown one.

So now let’s calculate the probability of selecting a brown socks out of the mix

That would be ;

number of brown socks/ total number of socks = 4/8 = 1/2

Now, for the left foot, we are having white sock here.

Kindly recall that since we already have a sock on the right foot, we have 7 socks left to pick from.

Now we need the probability of picking a white sock from the total 7. That would be ; 2/7

So the probability of both action occurring is simply the product of both probabilities and that is ;

1/2 * 2/7 = 1/7
