Answer: 50 - 10m or 10(5 - m)
Step-by-step explanation:
Since Lily starts a savings account with $50 and each month, m, she withdraws $10 from her account, the expression that can be used to determine the amount left in her savings account after a certain number of months will be:
= 50 - 10(m)
= 50 - 10m
For example, the amount that'll be left in her account after two months will be:
= 50 - 10m
= 50 - 10(2)
= 50 - 20
= 30
She'll have $30 in her account after two months.
James has 10 baseballs that each
have 5 signatures on them. James
says he has 45 signatures. Is James
correct? Explain.
Answer:No he is not correct.
Step-by-step explanation:
Since each baseball has signatures on them and he has 10 of them we have to multiply 10 by 5 and we get 50 not 45.So he had 50 signatures in total therefore is not correct.

Write an explicit formula for the geometric sequence below and use it to find the 9th term.
256, 64, 16, 4, . . .
Answer:
The explicit formula is;
Tn = 256(1/4)^(n-1)
The 9th term is;
256/65536
Step-by-step explanation:
Mathematically, we have the nth term of a geometric sequence as;
Tn = ar^(n-1)
a is the first term = 256
r is the common ratio = 64/256 = 16/64 = 4/16 = 1/4
So, for the 9th term, we have
T9 = 256(1/4)^(9-1) = 256/65536
The explicit formula is;
Tn = 256(1/4)^(n-1)

Evaluate the exponential expression. 14^2
Answer:196
Step-by-step explanation:
Answer:
196
Step-by-step explanation:
Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.
Which expressions are equivalent to 2 ( a + 3 b ) 2(a+3b)? Mark all that apply. A 2a+6b2a+6b B a+(a+6b)a+(a+6b) C 2b+3a2b+3a D a+3ba+3b E 2a+(5+1)b2a+(5+1)b F a2+b5a 2 +b 5 G
Answer:
A. 2a+6b
B. a+(a+6b)
D. a + 3b
E. 2a+(5+1)b
Step-by-step explanation:
Given:
2(a + 3b)
Open parenthesis
= (2a + 6b)
A 2a+6b
B. a+(a+6b)
= a + a + 6b
= 2a + 6b
C 2b+3a
Not equivalent
D. a + 3b
2a + 6b
Divide through by 2
= a + 3b
E. 2a+(5+1)b
= 2a + (6)b
= 2a + 6b
F. a2+b5
Not equivalent

How do you determine if triangles or any polygons are similar?
For example, all equilateral triangles are similar and all squares are similar. If two polygons are similar, we know the lengths of corresponding sides are proportional. In similar polygons, the ratio of one side of a polygon to the corresponding side of the other is called the scale factor.

we want to find the zeros of this polynomial:
p(x)=(x-1)(x+3)(2x+1)
plot all the zeros (x-intercepts) of the polynomial in the interactive graph.
Answer:
Step-by-step explanation:
To find the zeros of this polynomial, set the polynomial equal to zero, and then set each of the factors equal to zero separately. Solve each equation for x:
x - 1 = 0 yields x = 1. The x-intercept is (1, 0).
x + 3 = 0 yields x = -3. The x-intercept is (-3, 0).
2x + 1 = 0 yields x = -1/2 The x-intercept is (-1/2, 0)
Answer:
(- 3, 0), (- 1/2, 0), (1, 0)
Step-by-step explanation:
p(x)=(x-1)(x+3)(2x+1)
Plug p(x) = 0
Therefore,
(x-1)(x+3)(2x+1) = 0
x - 1 = 0 or x + 3 = 0 or 2x + 1 = 0
x = 1 or x = - 3 or x = - 1/2
Hence, (- 3, 0), (- 1/2, 0), (1, 0) are zeroes of the given polynomial

Suzanne owns stock worth $2,400. She owes $5,200 in student loans, and $2,500 on a credit car. She owes $1,800 on a car that is worth $8,000. What is Suzanne's net worth in dollars?
Answer:
15,100
Step-by-step explanation:
because 5,200+2,500+8,000+1,800=17,500 which is how much she owes and what she has is 2,400 so 17,500- 2,400= 15,100 so her net worth is 15,100

What is the equation of the following line?
9514 1404 393
Answer:
E. y = -4x
Step-by-step explanation:
The line goes through the origin, so the equation is of the form ...
y = kx
The constant of proportionality k has the value ...
k = y/x
The given point is (x, y) = (2, -8). Using these values in the expression for k, we have ...
k = -8/2 = -4
Then the equation is ...
y = -4x . . . . matches E
a2 = -8 and a5 = -512
Find a10
Answer:
The value of a₁₀ is -1352
Step-by-step explanation:
a₂ = -8
a₅ = -512
Now,
a₂ = -8 can be written as
a + d = -8 ...(1) and
a₅ = -512 can be written as
a + 4d = -512 ...(2)
Now, from equation (2) we get,
a + 4d = - 512
a + d + 3d = - 512
(-8) + 3d = - 512 (.°. a + d = -8)
3d = - 512 + 8
3d = - 504
d = - 504 ÷ 3
d = - 168
Now, for the value of a put the value of d = -168 in equation (1)
a + d = -8
a + (-168) = -8
a - 168 = -8
a = 168 - 8
a = 160
Now, For a₁₀
a₁₀ = a + 9d
a₁₀ = 160 + 9(-168)
a₁₀ = 160 - 1512
a₁₀ = -1352
Thus, The value of a₁₀ is -1352

Hi, my tutor sent this to me and I'm confused about what -1 represents. If anyone can give me a detailed solution to this question it would be greatly appreciated
Answer:
Sin, Cos, Tan and others are used to calculate the ratios of the sides of a right angled triangle by taking a certain angle as the angle of reference.
On the other hand, Sin‐¹, Cos‐¹ and Tan-¹ are used to find the reference angle used to calculate the ratio of sides.
For this question,
we need to find which option should used to calculate the angle the slide makes with the vertical support.
So the option will have to be either A, C or E.
here, the base is 2.81m and hypotenuse is 3.64m.
we know, Cos = base / hypotenuse
So the angle is given by Cos-¹(2.81/3.64)
Option C
9514 1404 393
Answer:
E. sin⁻¹(2.81/3.64)
Step-by-step explanation:
If you understand the question, you know that the relation of interest is ...
Sin = Opposite/Hypotenuse
sin(•) = 2.81/3.64
• = arcsin(2.81/3.64) . . . . matches choice E
If you want to find the angle, you need to use a function that gives the angle for a particular sine value. That function is called the arcsine function, or the inverse sine function. It is represented using the notation arcsin( ) or sin⁻¹( ). (The -1 is interpreted as being an exponent.)
__
You may recall the rules of exponents say ...
s^-2 = 1/s^2
Then the simple reciprocal, or inverse, is ...
s^-1 = 1/s^1 = 1/s
That is, an exponent of -1 signifies an inverse. This is the notation of choice to signify an inverse function. It is applied to the function name. (It does not mean the reciprocal of the function value.)
__
Additional comment
One needs to be careful with exponents on function names. An exponent of -1 on the name is generally understood to signify the inverse function.
Positive exponents greater than 1 can be ambiguous. Usually, we intend ...
[tex]\sin^2(x) = (\sin(x))^2[/tex]
Sometimes, we mean ...
[tex]f(f(x)) = f^2(x) \ne (f(x))^2 = f(x)^2[/tex]

Answer:
Correct answer is 8.9
Step-by-step explanation:
When you use the Pythagorean theorem formula a^2 + b^2 = c^2, we can easily calculate the missing side by plugging in the given numbers. So when you do the math, 2.8^2 + 8.5^2 it will give you 80.09, then when you square root it, it will be 8.9. And that is your answer
