Answer:
y = 3x + 1
Step-by-step explanation:
' y = 3x + 1 ' is a equation of a linear function. The equation is in slope-intercept form. All slope intercept-form lines are linear.
An equation for a linear function has no exponents, no variables in fractions, and no square roots.
Hope this helps.
It is given in the question that the solid is a cone with height of 16 units and radius of 7 units .
The formula of volume of cone is
To find the volume, we substitute the given values of r and h and use 3.14 for pi. That is
And that's the required volume of the cone .
Answer: it will cost $280
Step-by-step explanation:
The diagonal of the rectangular garden divides it into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
d² = 24² + 32²
d² = 576 + 1024 = 1600
d = √1600
d = 40 feet
If the path is 2 feet wide, then the area of the path is
Area = 40 × 2 = 80 ft²
If gravel costs $3.50 a square foot, then the cost to install the gravel path is
3.5 × 80 = $280
