for a graph of a quadratic i have x intercepts that are x=12 and x =35 do i have enough information to find the y-coordinate of the vertext and why

Answers

Answer 1

Answer:

No... provided no other information or no graph is provided.

Step-by-step explanation:

You can find the x-coordinate of the vertex which can be calculated using the two given x-intercepts. Using the symmetry of the parabola, it would just mean the vertex should lay midway between the x's. So the x-coordinate of the vertex is (12+35)/2=47/2.

However, we do not have enough information about the relationship between x and y to find the y-coordinate of the vertex.

All we are given is y=a(x-12)(x-35) (where a is real number) since we know the relationship is quadratic, and the zeros are 12 & 35.

So we could have many possible y-coordinates for our vertex since we don't know the value of a in our equation and we can plug in our x-coordinate for our vertex to find them all.

y=a(47/2-12)(47/2-35)

I'm just going to put everything to right of a in calculator:

y=-529/4 ×a

So that's all the possible y-coordinates for the vertex.

7. After 8 months, Joellen has lost 75 pounds. This is a 30% decrease in her starting weight. Find
her starting weight.

Answers

Answer:

Started 100% = x pounds

30% = 75 pounds

x= 75*100÷30= 250 pounds

Starting Weight = 250 pounds

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

30% = 75 pounds

100% = 250 pounds

The starting weight was 250 pounds.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

30% decrease = 75 pounds

Starting weight = 100%

Now,

30% = 75

Multiply 100/30 on both sides.

100/30 x 30% = 100/30 x 75 pounds

100% = 10/3x 75 pounds

100% = 10 x 25 pounds

100% = 250 pounds

Thus,

The starting weight was 250 pounds.

We know area or A = 420

and we know length or L = 21

(420) = (21) * W

Divide both sides of the equation by 21 to isolate the variable.

That leaves us with:

The leaning tower of Pisa is approximately 179 ft in “height” and is approximately 16.5 ft out of plumb. Find the angle at which it deviates from the vertical.

Answers

The angle at which the leaning tower of Pisa deviates from the vertical is approximately 5.31 degrees.

To find the angle at which the leaning tower of Pisa deviates from the vertical, we can use the concept of tangent function.

First, we need to calculate the distance that the top of the tower is displaced from the vertical axis. This can be done using the Pythagorean theorem, which states that the displacement (d) is equal to the square root of the height of the tower (h) squared plus the amount the tower is out of plumb (p) squared:

d = √(h² + p²)

d = √(179² + 16.5²)

d = 180.14 ft

Next, we can use the tangent function to find the angle of deviation (θ):

tan(θ) = p/h

tan(θ) = 16.5/179

θ = tan⁻¹(16.5/179)

θ ≈ 5.31 degrees

Here, we want to round to a tenth (0.1), so we first add half that value:

The expression three times the quantity two decreased by x is nine is - 1

A quantity two decreased by x can be expressed thus :

(2 - x)

Multiplying the quantity by 3 :

3(2 - x)

The expression can be written Mathematically as thus : 3(2 - x) = 9

The expression can be expanded further as :

3(2 - x) = 9

6 - 3x = 9

-3x = 9 - 6

-3x = 3

x = (3 ÷ -3)

x = - 1

Step-by-step explanation:

this asks for the median, and not the mean value.

please notice that these 2 values are often if not mostly different from each other.

the median just defines the middle of the value interval, so that half of the different values are left, and half are right of that median value.

here we have 7 values. do we find one, so that 3 other values are smaller, and 3 other values are bigger than that ?

that is 15.

10, 12, 13 are smaller.

Answer:

Answer:

Restaurant A's chicken salad has  7.7 grams of fat.

Restaurant​ B's chicken salad has  61.6 grams of fat.

Restaurant​ C's chicken salad has  7.7 grams of fat.

Step-by-step explanation:

Restaurant A = C

Restaurant B = 8 × Restaurant A

Total Grams of Salad = 77

Let Reataurat A and C be x

and Reataurant B be 8x

so

A + B + C = 77

x + 8x + x = 77

2x + 8x = 77

10x = 77

x = 77 ÷ 10

x = 7.7

Restaurant A's chicken salad has  7.7 grams of fat.

Restaurant​ B's chicken salad has  61.6 grams of fat.

Restaurant​ C's chicken salad has  7.7 grams of fat.
