Price = (p + 1)(b)

In this scenario, the variable 'p' represents the profit in percentage (This equation assumes that you input percentage in a decimal).

'b' represents the base price or the original price.

the area of a circle is : pi×r²

the circumference of a circle is : 2×pi×r

with r being the radius, which is half of the diameter.

so, here, r = 10/2 = 5 m

area = pi×r² = pi×5² = pi×25 or 25×pi m²

circumference = 2×pi×r = 2×pi×5 = 10×pi m

for the approximation we make the calculations with pi on the calculator and round to the nearest hundredth.

area = 25×pi ≈ 78.54 m²

circumference = 10×pi ≈ 31.42 m

for all values of x , a function f is defined by f(x)=x^2+7x+12 if f(a)=2, what could be the value of a?

Evgesh-ka [11]

Answer:

a = -2 or a = -5

Step-by-step explanation:

We want $f(a) = a^2 + 7a + 12 = 2$ . We can subtract 2 from both sides of this equation to get $a^2+7a+10=0$ . We can factor this to get that $(a+2)(a+5)=0$ . When the product of two numbers is equal to zero, one of the numbers must be equal to zero. This means that either a + 2 = 0, in which case a = -2, or a + 5 = 0, in which case a = -5.
