See below for the description of the figure
<h3>How to describe the figure?</h3>
The equation is given as:
36 + 27 = 9 * (4 + 3)
Open the bracket
36 + 27 = 9 * 4 + 9 * 3
The above when represented on a figure is represented by the given figure.
From the figure, we have the following highlights:
- There are two partitions on the figure
- One represents 9 * 4, while the other represents 9 * 3
This means that the figure has 7 columns and 9 rows where the partitions on the figure are the product of the rows and column in each partition

Step-by-step explanation:
ok, logic
all of them are parabolas
1st and 3rd are opening up, so they defenitely increase, so no
decraseing
the vertex hs to be be at x=-4
y=a(x-h)^2+k
h has to be -4
y=a(x+4)^2+k
the answer is 2nd one or f(x)=-(x+4)^2+4
Answer:
B
Step-by-step explanation:
Formula is
Interest=loan ×interest rate×time
Solve for the first choice
I=10,000×0.05×5=2500
Solve for the second choice
I=10,000×0.06×7=4200
The difference in the amount of interest
4,200−2,500=1700
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
Answer:
AB=8cm
Step-by-step explanation:
Since ABC is a right angled triangle,
Using pythagoras theorem,
h²=p²+b²
or, BC²=AC²+AB²
or, 17²=15²+AB²
or, 289=225+AB²
or, 289-225=AB²
or, AB² = 64
so, AB=8 cm
