Area = 1/2 x base x height

Area = 1/2 x 9 x 4

Area = 9 x 2

Area = 18 cm^2

The formula is half base times the height. That would mean 9 x 4= 36, then you half 36, which gives you 18. Please tell me if you don't understand, I might have a bad explanation

Let f(x)=x2−18x+157 .

mrs_skeptik [129]

Hello :
f(x)=x²−18x+157
= x²-2(9)(x) +9²-9²+157
= (x-9)² -9²+157
f(x) = (x-9)²+76....(the vertex form of f(x) )
Minimum value of f(x): y = 76

Find the area of each figure. Please help <3 it would be appreciated! (30 points)

Annette [7]

Answer:

$1,824 \: {in}^{2}$

Step-by-step explanation:

Area of the figure = Area of rectangle with dimensions 48 in and 32 in + Area of triangle with base 48 in and height 12 in.

$= 48 \times 32 + \frac{1}{2} \times 48 \times 12 \\ \\ = 1,536 + 24 \times 12 \\ \\ = 1,536 + 288 \\ \\ = 1,824 \: {in}^{2}$

Use the pythagorean theorem to write an equation for the distance Jane's trainer bikes.

ankoles [38]

Complete question is;

Jane is training for a triathlon. After swimming a few laps, she leaves the health club and bikes 16 miles south. She then runs 12 miles west. Her trainer bikes from the health club to meet jane at the end of her run. Use the pythagorean theorem to write an equation for the distance janes trainer bikes

Answer:

x = √(12² + 16²)

Step-by-step explanation:

We are told that;

She bikes from health club to South = 16 miles

From South to West = 12 miles

Her trainer bikes from the health club to meet her at the end which is west.

I have attached a diagram showing this movement in form of a triangle.

From the diagram I attached, I have depicted the distance the trainer bikes as x.

Using pythagoras theorem;

x² = 12² + 16²

x = √(12² + 16²)
