If you do not have a graphing calculator the best thing to use is Desmos. Desmos is free -- anyone can use it and and the graphs can be used here on Brainly.  I've downloaded the graph for you.

There are a couple of things you should notice.

The most downward point is (-5,-3)

The largest root is x =   -2

The smallest root is x = - 8

Notice the roots are the opposite of what you are given. You will eventually learn how to do all of these things.

if im correct the answer is 48 ft2

Step-by-step explanation:

Answer:

[tex]16ft \: ^{2} [/tex]

Step-by-step explanation:

To find the area of the given triangle we'll use the formula:-

[tex]\boxed{\sf A = \cfrac{1}{2} \times b \times h}[/tex]

Where,

[tex]\sf A = \cfrac{1}{2} \times 8 \times 4[/tex]

First, let's multiply 1/2 * 8 = 8/2.

Divide 8 by 2= 4

Thus, the area of the triangle is 16ft^2.

Step-by-step explanation:   4+3+2+5

Answer:

  18

Step-by-step explanation:

The summation symbol is telling you there are 4 terms of the sum. The values of x in the terms range from 1 to 4.

__

The expanded form of the sum is ...

  (1 +2) +(2 +2) +(3 +2) +(4 +2)

  = 3 +4 +5 +6 = 18

The sum is 18.

_____

Additional comment

The sum can be rewritten as ...

  [tex]\displaystyle \sum_{x=1}^4{(x+2)}=\sum_{x=1}^4{x}+\sum_{x=1}^4{2}=\dfrac{4(4+1)}{2}+4\times2=10+8=\boxed{18}[/tex]

This way, you need to know the sum of integers from 1 to n is (n/2)(n+1). It may be easier just to write the terms out as we have done above.

Answer:

14.375 Or 115/8

Step-by-step explanation:

since 8 7/8 = 71/8 and 7 5/6 = 47/6 and 2 1/3 = 7/3

then 71/8 + ( 47/6 - 7/3) = 115/8

Answer:

11

Step-by-step explanation:

First, you replace x with 2

5×2+1

Then multiplication comes before addition so 5×2

5×2=10

Then just add the 1

Answer:

$2.15

Step-by-step explanation:

$5 - $2.85 = $2.15

this is the explanation

The cost of dry bag is $2.85 then the change does Alka get back will be $2.15.

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the mentioned information in the question,

Cost of dry bag = $2.85

Money given by Alka for the bill = $5.00

Then, the amount she will get back,

($5.00 - $2.85) = $2.15

The maximum value of the objective function p if p = 180x + 250y is 3020

The coordinates of the feasible region are given as;

(14, 2), (0, 9), (6, 8), and (10, 3)

The objective function is given as:

P = 180x + 250y

Substitute the coordinates of the feasible region in the above function

P = 180 * 14 + 250 * 2 =3020

P = 180 * 0 + 250 * 9 = 2250

P = 180 * 6 + 250 * 8 = 3080

P = 180 * 10 + 250 * 3 = 2550

The maximum value in the above computation is:

P = 180 * 14 + 250 * 2 =3020

Hence, the maximum value of the objective function p if p = 180x + 250y is 3020

Step-by-step explanation:

9 goes into 50 4 times and the subtract that from 50

Answer :

5 [tex]\frac{5}{9}[/tex]

Explanation:

50/9= 5.5555555555556 = 5

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (5) and multiply it by the original denominator (9). The result of that multiplication is then subtracted from the original numerator:

50 - (9 x 5) = 5

Step 3: Our mixed fraction

We've now simplified 50/9 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

Answer:

Step-by-step explanation:

6 / 3√5

= 2/√5

= 2√5/5

Answer:

 [tex]\frac{2\sqrt{5} }{5}[/tex]

Step-by-step explanation:

First, you can take a factor of (3) out of the numerator and denominator. This simplifies to equal 1, so you are left with 3/√5.

6 / 3√5   ----->   (3/3)  x  2/1√5  --->  (1)  x  2/√5  --->  2/√5

Because radicals should not be kept in the denominator, multiply both the numerator and denominator by the radical of 5. This removes the radical from the denominator while altering both the numerator and denominator equally. Remember, the square root of a number is technically the number raised to the 1/2 power. The 1/2 power times the 1/2 power equals the power of one, essentially "eliminating" the radical.

2/√5  --->  2/√5  x  √5/√5  --->  2√5 / 5

As there is not way to simplify further, your final answer should be [tex]\frac{2\sqrt{5} }{5}[/tex].

Find the volume of a sphere with a diameter of 16 cm using the formula Volume = [tex]\dfrac{4}{3}[/tex] × π × r³.

In this question we are provided with the diameter of a sphere. We are asked to calculate the volume of the sphere using the radius.

First we will find the radius of the sphere

We know,

[tex] ✭ \: \small\boxed{ \rm{ Radius = \dfrac{Diameter}{2}}}[/tex]

Substituting the values we get

[tex] \small\sf{ Radius = \dfrac{ \cancel{16} \: \: 8}{ \cancel{2}}}[/tex]

[tex] \star \: \small\rm{ Radius = 8 \: cm}[/tex]

Now we will calculate the volume of the sphere

We know,

[tex] ✭ \: \small \boxed{{\rm{ Volume_{(sphere)} = \dfrac{4}{3} × π × r³}}}[/tex]

Where,

Substituting the values we get

[tex] \small\rm{ Volume_{(sphere)} = \dfrac{4}{3} × 3.14 × 8³}[/tex]

[tex]\small\rm{ Volume_{(sphere)} = \dfrac{ \cancel{4}}{3} × 3.14 × 8 \times 8 \times \cancel{ 8 } \: \: 2}[/tex]

[tex] \small\rm {V olume_{(sphere)} = \dfrac{3.14 × 64}{3}}[/tex]

[tex] \small\rm{ Volume_{(sphere)} = \dfrac{200.96}{3} =66.98 \: {cm}^{3} }[/tex]

Hence the volume of the sphere is 66.98 cm³.

The value of f(-3) for the function f(a)  = -2a² - 5a + 4 is 1.

Function relates input and outputs. The outputs are called the ranges of dependent variables while the input are called domain or independent variables.

Therefore,

f(a)  = -2a² - 5a + 4

Hence,

f(-3) = -2(-3)² - 5(-3) + 4

Therefore,

f(-3) = -18 + 15 + 4

f(-3) = -3 + 4

f(-3) = 1
