Step-by-step explanation:
Esh deposits $3500 in an account that
earns 3.75% interest each year. After the
first year, Esh has $3631.25 in the account.
After the second year, Esh has $3767.42 in
the account, and after the third year Esh has
$3908.70 in the account.
Answer:
Compound interest
Step-by-step explanation:
The question requires us to determine if the interest earned is a simple or compound interest
Simple interest = amount deposited x time x interest rate
Future value with compounding = A( 1 + r)^n
A = amount deposited
r = interest rate
n = time
We would calculate the simple interest and the future value in year 2
Simple interest in year 2 = $3500 x 0.0375 x 2 = 262.50
Future value in 2 years with a simple interest = 262.50 + 3500 = $3762.50
Future value in year 2 with compounding = 3500 x (1.0375)^2 = $3767.42
The value provided in year 2 with compounding matches that provided in the question. Thus, it is compounding of interest that is done

Answer:
f(x) = 4x^2 - 13
Step-by-step explanation:
f(x)=4(x-2)^2 + 3 parentaties first
f(x) = 4 (x^2 - 4)+ 3 multiply by what's infront parentaties
f(x) = 4x^2 - 16 + 3 combine light terms

Step-by-step explanation:
Given,
a = - 2
b = 5
Our expression is,
a² + b.
To solve this, we need to substitute the values of a & b in the given expresssion. So,
a² + b
= (-2)² + 5
= 4 + 5 (2 negatives when mutilpied gives a positive number)

What is the solution to the equation p + 7.2 = 11?
p = 3.2
p = 3.8
p = 4.8
p = 18.2
Answer:
p = 3.8
Step-by-step explanation:
11 - 7.2 = 3.8
Answer:
p = 3.8
Step-by-step explanation:
We have the equation p + 7.2 = 11 and are asked to solve for "p".
To do so, all we need to do is isolate p :
p + 7.2 = 11
Subtract 7.2 from both sides :
p = 3.8

ABC is a straight line. Work out the size of the angle marked x
Answer:
x = 57°
Step-by-step explanation:
angles on a straight line add up to 180°. to work out x, we need to subtract 70 and 53 from 180, to get the remaining angle, aka angle x. 180-70=110.
110-53= 57. therefore, x = 57°.
The measure of angle x in the straight line ABC is 57 degrees
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram:
x + 53 + 70 = 180° (sum of angles in a straight line).
Hence:
x = 57°
The measure of angle x in the straight line ABC is 57 degrees

Sketch the graph of the following equations: y=x+5, y=-(x+5), and y = |x+5|
The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Equations are,
y = x + 5
y = - (x + 5)
y = |x + 5|
Since, All equations shows equation of line.
Hence, We can draw all the equations as shown in figure.
y = x + 5
Slope = 1
y - intercept = 5
y = - x - 5
Slope = - 1
y - intercept = - 5
Thus, The graph of functions y=x+5, y=-(x+5), and y = |x+5| are shown in figure.
