Answer:
Step-by-step explanation:
this equation is written in y = mx + b form
m = slope
b = the y intercept
so if we rearrange the equation to
y = -23x -6
the slope is -23
the y intercept is (0, -6)
Answer:
A = 112cm²
Step-by-step explanation:
Area of a triangle = (bh) / 2
b = base length and h = height
The triangle shown has a given base length of 14cm and a given height of 16cm
Hence area = ( 16 * 14 ) / 2
16 * 14 = 224
224 / 2 = 112
A = 112cm²
Hey there! :)
You have to use the Pythagorean Theorem ⇒ a² + b² = c²
a = 5
5² = 5 × 5 = 25
b = 13
13² = 13 × 13 = 169
169 + 25 = 194
√194 = 13.93
That means McKenzie is correct and Cara is wrong ; c = 13.93
Hope this helps :)

The surface area of hemisphere is given by:
Where r is radius of hemisphere.
We are given diameter = 250 ft.
We know that radius = half of diameter.
Radius of dome = 1/2 (250) = 125 ft.
Now let us plug the value of radius in the formula,
Surface Area of dome = 98125 square foot.
