Step-by-step explanation:

3x^2 + 24x + 48 + 43 - 48

3(x^2 + 8x + 16) - 5

3(x + 4)^2 - 5

vertex at (-4,-5)

Answer:

vertex = (- 4, - 5 )

Step-by-step explanation:

The equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = 3x² + 24x + 43 ← factor out 3 from the first 2 terms

  = 3(x² + 8x) + 43

To complete the square

add/subtract ( half the coefficient of the x- term)² to x² + 8x

y = 3(x² + 2(4)x + 16 - 16) + 43

y = 3(x + 4)² - 48 + 43

y = 3(x + 4)² - 5 ← in vertex form

with vertex = (- 4, - 5 )

Answer: 7/4

Step-by-step explanation: To find the slope of a line, pick any two integer points, in this scenario the only two are (3,4) and (-1,-3). The slope is the rise over run, so think about it. To get from (-1,-3) to )3,4) you need to rise 7 units (difference in y coordinates) and from there you need to run 4 units, so it is 7/4. Keep in mind that rising up is positive for y and running to the right is positive for x.

Answer:

[tex]\frac{7}{4}x[/tex]

Step-by-step explanation:

How do you find slope on a graph? The slope is "rise/run" where "rise" is how much y spaces are moved to the next point and "run" is the how much spaces are moved to the next x point.

Step One: In this case, the point moves up 7 spaces to the next point, so that's the "rise" and then it moves 4 spaces to the right to the next point, so that's the "run"

Step Two: When we put it together, it is 7/4x. The x is just an indication that this is slope, and you don't have to worry about it until you learn how to plug it in.

Answer:

364×180=65,520 baskets

Step-by-step explanation:

since its a leap year(4days as shown in the document)

2nd question:

365×180=65,700 baskets

since its not a leap year

if u dont know leap years end with an even number which is 364 and non leap years end with odd number which is 365.

Answer:

15ft

Step-by-step explanation:

Answer:

first circle is radius= 12.5 inches and diameter= 25 inches

second circle is radius=2 feet and diameter=4 feet

Step-by-step explanation:

radius is the point halfway down the circle. diameter is full length straight across the whole circle.

further analysis;

in the first circle it gives you the diameter which is 25 inches. in order to get the radius you cut 25 in half which is 12.5 inches.

in the second circle it gives you the radius which is 2 feet. in order to get the diameter you need to double 2 feet which is a total of 4 feet.

Answer:

8. center: (-7,5)

radius: 9

Step-by-step explanation:

8. to find the center, you need to get the equation in the form of (x-h)^2+(y-k)^2=r^2

you can do this by completing the square:

x^2+y^2+14x-10y-7=0

x^2+14x+49+y^2-10y+25=7+49+25

(x+7)^2+(y-5)^2=81

so, the center is (-7,5) and the radius is 9

Answer:

Step-by-step explanation:

Answer:

12

Step-by-step explanation:

y = kx where 'k' is the constant of proportionality

24 = 2 x 12

36 = 3 x 12

48 = 4 x 12

60 = 5 x 12

Answer: C. K= 2.5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

[tex]\Huge\boxed{k=2.5}[/tex]

Step-by-step explanation:

Given -2.1k + 13 + 6.5k = 24 we need to isolate the variable using inverse operations

step 1 combine any like terms

sometimes there are not like terms but in this case there are. When there are like terms (must be on the same side of the = ) you add them together

-2.1k + 6.5k = 4.4k

now we have

4.4k + 13 = 24

Now we want to get rid of the 13

To do so we subtract 13 from each side

13 - 13 cancels out

24 - 13 = 11

now we have 4.4k=11

now we want to get rid of the 4.4

To do so we divide each side by 4.4

4.4k/4=k

11/4.4=2.5

we're left with k - 2.5

Answer:

4 pounds 12 ounces

Step-by-step explanation:

there are 16 ounces in 1 pound so 76/16 = 4.75 and .75 is equal to 12 ounces.

76 ounces is equal to 4 pounds and 12 ounces.

To convert 76 ounces to pounds and ounces, we need to consider that 1 pound is equal to 16 ounces.

Here's how to proceed:

Divide the total number of ounces by 16 to find the number of pounds:

76 ounces ÷ 16 ounces/pound = 4.75 pounds

Since 4 pounds = 4 x 16 pounce/ pound

= 64 ounces ,we subtract this amount from the total of 76 ounces to determine the remaining ounces:

= 76 ounces - 64 ounces

= 12 ounces

Therefore, 76 ounces is equal to 4 pounds and 12 ounces.

Answer:

64? I'm not sure but because if 1= girls (8 girls) and boys is 8 times more you do 8x8 I think sorry if I'm wrong

Answer:

There are 64 boys

Step-by-step explanation:

If there are 8 girls it would be 8*1

so you would have to multiply 8 by the ratio of boys which is 8*8

which equals 64 boys to 8 girls (8:1)

Answer:

x = 6

Step-by-step explanation:

We solve that above question using the trigonometric function of Tangent

Tan theta = Opposite/Adjacent

Theta = 45°

Opposite = 6

Adjacent = x

tan 45° = 6/x

tan 45 in rational form = 1

1 = 6/x

Cross Multiply

x = 6

π(2(49) + 2(112)) → π(98 + 224) → π(322)

Answer:

x=18

Step-by-step explanation:

Answer:

x= 18

Step-by-step explanation:

To solve this equation you have to work backwards

Start by dealing with the numbers that we know:

450 + (28.75 × x) = 967.5

-450                          -450

28.75x = 967.5

(when a number and a letter in mathematics are next to each other they are multiplying)

Now divide to find the value of x:

967.5 ÷ 28.75 = 18

18 is the value of x

Answer: Greater than or equal to 2.

Step-by-step explanation:

Given

Function is  [tex]f(x)=2x^2+5\sqrt{x-2}[/tex]

The entity inside a square root is always positive i.e. greater than equal to zero

[tex]\therefore \ x-2\geq 0\\\Rightarrow x\geq2[/tex]

So, the domain of the function is all real numbers greater than or equal to 2.
