Answer:
F =
Step-by-step explanation:
Given
C = ( multiply both sides by 9 )
9C = 5(F - 32) ← distribute
9C = 5F - 160 ( add 160 to both sides )
9C + 160 = 5F ( divide both sides by 5 )
= F
Answer:
a = - 3, a = 4
Step-by-step explanation:
Given f(x) = x² + 2 and g(x) = x + 14 , then
f(a) = a² + 2 and g(a) = a + 14
For f(a) = g(a) , then equate the right sides
a² + 2 = a + 14 ( subtract a + 14 from both sides )
a² - a - 12 = 0 ← in standard form
(a - 4)(a + 3) = 0 ← in factored form
Equate each factor to zero and solve for a
a + 3 = 0 ⇒ a = - 3
a - 4 = 0 ⇒ a = 4
Answer:
y = 5(1.8)^x
Step-by-step explanation:
the formula for an exponential equation is y = a(b)^x
the a in this case is the starting number which is 5000
y = 5000(b)^x
the b is the percentage in decimal form
0.8 BUT it is an increase so we add 1
1.8
y = 5000(1.8)^x
because the graph is in thousands we can make 5000 into 5
Answer:
b. an interval of data
Step-by-step explanation:
A histogram is a chart that plots the distribution of a numeric variable's values as a series of bars. Each bar typically covers a range of numeric values called a bin or class; a bar's height indicates the frequency of data points with a value within the corresponding bin.
