Answer: The graph will appear as a parabola opening downwards with a maximum point. It will cut the y-axis at -11.
Step-by-step explanation:
The coefficient of x^2 is negative, thus the graph will look "sad" ie. max a maximum point and open downwards. And bc it's x^2, it's a parabola.
Sub. x=0 and you'll get -11. Or just inspect and get the ans from the eqn.
to get the roots. ( x-intercepts). Just sub y=0 and solve.

what is the cube root of 27/64?
Answer:
⅜
Step-by-step explanation:
We want to find the cube root of 27/64.
∛(27/64)
We know that;
3³ = 27 and 8³ = 64
Thus;
∛(27/64) = ⅜
5. How long is the diagona of a 12 ft-by-16 ft rectangular garden?
A. 6 ft
B. 14 ft
C. 18 ft
D. 20 ft
Answer:
The correct answer is option D, 20ft
Step-by-step explanation:
After drawing the picture below, you can just use pythagorean theorem to solve for the diagonal, or the hypotenuse in this case;
(Length)² + (Width)² = (Diagonal)²
(16)² + (12)² = (Diagonal)²
256 + 144 = (Diagonal)²
400 = (Diagonal)²
[tex]\sqrt{400}[/tex] = [tex]\sqrt{Diagonal^{2} }[/tex]
20 = Diagonal
Hope this helps!
Answer:
D. 20 ft
Step-by-step explanation:
Use pythagorus! We can imagine the rectangle is split into 2 equal triangles, one side of the triangle being 12, and the width being 16.
Pythagorus theorum is used to calculate the hypotenuse (long side) of a right-angled triangle. This is the formula:
[tex]\sf{a^{2}+b^{2} = c^{2} }[/tex]
So, we do 12^2 (squared) + 16^2 =
144 + 256 = 400
Now, we have to find the square root of 400, which is equal to
20
So our answer is 20ft
Hope this makes sense! If you need further explanation, do let me know...

Find the value of k that makes the equation true.
Group of answer choices
k=10
k=9
k=7
k=6
Answer:
k=9
Step-by-step explanation:
K=9, because if you plug in 9 as k(2(9)=18)the equation is true.
Answer:
k=9
Step-by-step explanation:
2 × 9 = 18 which is the same as 9 + 9=18
Dan weighs 205 pounds but is only 5 feet 8 inches tall. Evan is 6 feet tall. How much would you expect Evan to weigh if they have the same height/weight ratio?
Answer:
217.1 lbs
Step-by-step explanation:
I did set up cross multiplication using the height/weight ratio.
68/205 and 72/?.
72*205=14760
14760/68=217.05
Then I rounded to get 217.1 lbs
Benson has a bankruptcy on his credit report, so he pays higher interest rates on his current loans. he calculates that the extra money he pays in additional interest each year, if invested at the rate of 2% for one year, could earn him simple interest totaling $180. how much does benson pay in additional interest each month? a. $360 b. $750 c. $900 d. $1,000 please select the best answer from the choices provided. a b c d
The additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year, option (b) is correct.
What is simple interest?It is defined as the interest on the based on the principal amount, it does not include the compounded amount. The interest calculate on the initial amount or borrowed amount.
We know the formula for the simple interest is given by:
I = PRT
Where I is the simple interest.
P is the principal amount
R is the rate of interest
We have in the question:
I = $180
R = 2% = 0.02
T = 1 year
Put the above values in the formula, we get:
180 = P(0.02)(1)
P = $9000
The additional interest Benson pay each month is:
= 9000/12
= $750
Thus, the additional interest Benson pay each month is $750 if he invested at the rate of 2% for one year option (b) is correct.

A kangaroo chases a rabbit that starts 150 feet ahead of the kangaroo. For every 12-foot leap of
the kangaroo, the rabbit makes a 7-foot leap. How many leaps will the kangaroo have to make to
catch up to the rabbit if the two animals always leap at the same time?
Answer:
30 leaps
Step-by-step explanation:
Equation of rabbit:
y=7x+150
Equation of kangaroo:
y=12x
To solve the system of equations, use substitution
12x=7x+150
5x=150

Which statement is true of a rectangle that has an area of 4x2 39x – 10 square units and a width of (x 10) units? the rectangle is a square. the rectangle has a length of (2x – 5) units. the perimeter of the rectangle is (10x 18) units. the area of the rectangle can be represented by (4x2 20x – 2x – 10) square units.
The length and width of the rectangle are (4x - 1) and (x + 10) then the perimeter of the rectangle is 10x + 18. Then the correct option is C.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The polynomial of the rectangle will be given below.
4x² + 39x – 10
The factor of the polynomial will be
(4x - 1)(x + 10)
Then the perimeter of the rectangle will be
Perimeter = 4x - 1 + 4x - 1 + x + 10 + x + 10
Perimeter = 10x + 18
