Howard deposited some money in the bank. How long will Howard have to leave $5000 in the bank to earn $250 in simple interest at 2%.
Answer:
t = 2.5 years
Step-by-step explanation:
Given that,
Principal = $5000
Interest = $250
Rate of interest = 2%
We need to find the time. We know that,
[tex]I=\dfrac{PRT}{100}[/tex]
Put all values to find T.
[tex]T=\dfrac{100I}{PR}\\\\T=\dfrac{100\times 250}{5000\times 2}\\\\T=2.5\ yrs[/tex]
So, it will take 2.5 years.

Answer:
[tex]5.5\times 10^{-1}[/tex]
Step-by-step explanation:
We need to find the value of the given expression i.e.
[tex]\dfrac{6.8\times 10^3-7.2\times 10^2}{1.1\times 10^4}[/tex]
We can solve it as follows :
[tex]=\dfrac{6800-720}{11000}\\\\=\dfrac{6080}{11000}\\\\=0.55[/tex]

area of the triangle 15
area of the rectangle 104
104-15=89m
Answer:
[tex]89[/tex] [tex]m^{2}[/tex]
Step-by-step explanation:
area of a triangle = [tex]\frac{bh}{2}[/tex]
so [tex]\frac{(5)(6)}{2}[/tex] = 15 [tex]m^{2}[/tex]
area of a rectangle = [tex]\\ bh[/tex]
so [tex]\\ 8[/tex]×[tex]\\ 13[/tex] [tex]\\ = 104[/tex] [tex]m^{2}[/tex]
so the area of the figure is
[tex]\\ 104[/tex] [tex]m^{2}[/tex] - 15 [tex]m^{2}[/tex] = [tex]89[/tex] [tex]m^{2}[/tex]
Which equation does not belong with the other three?

А
D
15y = 6x
2
y = -x
5
10y = 4x
5xy = 2
OD
ОА
B
Ос
Answer:
The Right option is D
Step-by-step explanation:
From the picture below,
For A,
15y = 6x
Where we divide both side of the equation by 3
15y/3 = 6x/3
5y = 2x
For B,
y = 2/5(x)
y×5 = 2x
5y = 2x.
For C,
10y = 4x
Divide both side of the equation by 2
10y/2 = 4x/2
5y = 2x.
For D,
5xy = 2. It can not be simplified futher.
Therefore,
From the above simplification, We can see that,
Equation A = Equation B = Equation C.
Equation D is the only Equation that does not belong to the other three.
Hence the right option is D

Topic: Reduced row echelon form
Thanks for the help in advance
Let f, s, and t denote the hours needed by the first, second, and third sellers, respectively, to sell a given plant.
"In one hour, the first grower sells 3 fly traps … The second grower sells 1 fly trap … The third grower sells 3 fly traps …" - this means that for each hour f, the first grower sells a total of 3f fly traps. Similarly, the second grower sells 1s fly traps, and the third grower sells 3t fly traps. Together, they want to sell 39 fly traps, so that
3f + s + 3t = 39
You set up two more equations for the sundews and bladderworts:
f + 2s + 2t = 30
2f + s + 2t = 28
Now write the system of equations in augmented matrix form and row reduce it:
[tex]\left[\begin{array}{ccc|c}3&1&3&39\\1&2&2&30\\2&1&2&28\end{array}\right][/tex]
Add row 1 to -3 (row 2); this is to say, treating each row as a list, multiply through the second row by -3, then add the first row to that result. For example,
(3, 1, 3, 39) + -3 (1, 2, 2, 30) = (3, 1, 3, 39) + (-3, -6, -6, -90)
… = (3 - 3, 1 - 6, 3 - 6, 39 - 90)
… = (0, -5, -3, -51)
Also, add 2 (row 1) to -3 (row 3) :
[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&-5&-3&-51\\0&-1&0&-6\end{array}\right][/tex]
Multiply through the last two rows by -1 to make everything positive, and swap them around:
[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&1&0&6\\0&5&3&51\end{array}\right][/tex]
Next, add -5 (row 2) to row 3 :
[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&1&0&6\\0&0&3&21\end{array}\right][/tex]
Multiply through row 3 by 1/3 :
[tex]\left[\begin{array}{ccc|c}3&1&3&39\\0&1&0&6\\0&0&1&7\end{array}\right][/tex]
Add -1 (row 2) and -3 (row 3) to row 1 :
[tex]\left[\begin{array}{ccc|c}3&0&0&12\\0&1&0&6\\0&0&1&7\end{array}\right][/tex]
Multiply through row 1 by 1/3 :
[tex]\left[\begin{array}{ccc|c}1&0&0&4\\0&1&0&6\\0&0&1&7\end{array}\right][/tex]
This row-reduced matrix tells you that f = 4, s = 6, and t = 7. In other words, in order for the three growers to collectively sell the required number of plants, the first seller needs to work for 4 hours, the second seller needs to work for 6 hours, and the third seller needs to work for 7 hours.
I dont know the answer!! I give brainlist...
Answer:
A. (f + g)(1) = - 9
B. (f - g)(0) = -7
C. (fg)(3) = 0
Step-by-step explanation:
A. (f + g)(1) = f(1) + g(1) f(1) = 1^2 - 9 = 1 - 9 = - 8 g(1) = 1 - 2 = - 1
= -8 -1 = -9
B. (f - g)(0) = f(0) - g(0) f(0) = 0^2 - 9 = 0 - 9 = -9 g(0) = 0 - 2 = -2
= -9 + 2 = -7
C. (fg)(3) = f(3)(g(3) f(3) = 3^2 - 9 = 9 - 9 = 0 g(3) = 3 - 2 = 1
= 0(1) = 0

Sherane rolls a standard, six-sided number cube. Find p (not composite).
Answer:
2/3
Step-by-step explanation:
A six sided number cube :
Sample space = (1, 2, 3, 4, 5, 6)
Non composite numbers on a six sided number cube = (1, 2, 3, 5)
Probability of an event = required outcome / Total possible outcomes
Required outcome = number of non composite numbers = 4
Total possible outcomes = sample space = 6
P(not composite) = 4 / 6 = 2/3

Answer:
Well, for (D), the answer would be 32.
Step-by-step explanation:
Because, 20 +12 =32. And 32 - 12 = 20. With the other ones that add, its the same way. You can just for example, if its -5 + b = -40, you can just go 5 - 40= which equals 35. Which should give you 40 if you add 35 and 5 together.

plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 132 t + 108 h ( t ) = - 16 t 2 + 132 t + 108 models the ball's height above the ground, h ( t ) h ( t ) , in feet, t t seconds after it was thrown. a) What is the maximum height of the ball?
Answer:
The maximum height of the ball is 380.25 feet in the air.
Step-by-step explanation:
The quadratic function:
[tex]h(t)=-16t^2+132t+108[/tex]
Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.
We want to determine the maximum height of the ball.
Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.
Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:
[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]
In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:
[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]
So, the maximum height occurs after 4.125 seconds of the ball being thrown.
To find the maximum height, substitute this value back into the equation. Thus:
[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]
The maximum height of the ball is 380.25 feet in the air.

The second statement.
Step-by-step explanation:
Any increasing exponential function will always eventually be greater than any other non-exponential function.
The statement that is true from the function given above is:
"Over the interval [-2, 2], function f is increasing at a faster rate than function g is decreasing." (Option D)
A function in mathematics is known as an expression of a relationship involving two variables:
Dependent and Independent, using a mathematical connotation.Why is option D a True statement?It is clear from the number array (attached) that x > 0, f(x) ↑ while x< 0 f(x) ↓.
While for g(x) it is confirmed that 0 <x<2, gx) ↓.

Find the lateral area of this cone.
Leave your answer in terms of pi.
3cm
4cm
The lateral area of the cone is 20π square centimeters.
Given that a cone with base radius of 4 cm and the height is 3 cm, we need to find the lateral area of the cone,
The lateral area of a cone can be calculated using the formula:
Lateral Area = π r l
where:
π is a mathematical constant approximately equal to 3.14159.
r is the radius of the base of the cone.
l is the slant height of the cone.
To find the slant height, we can use the Pythagorean theorem.
The slant height (l) is the hypotenuse of a right triangle formed by the height (h) and the radius (r) of the cone.
The formula is:
l = √(r² + h²)
Given that the base radius (r) is 4 cm and the height (h) is 3 cm, we can calculate the slant height (l):
l = √(4² + 3²)
= √(16 + 9)
= √(25)
= 5
Now we can substitute the values into the formula for the lateral area:
Lateral Area = π r l
= π × 4 × 5
= 20π
Therefore, the lateral area of the cone is 20π square centimeters.
