For the following arithmetic sequence: 4, ___, ____, ____, 24 a)Describe the term-to-term rule.
Answer: 4,9,14,19,24
The term to term rule is "add 5"
Step-by-step explanation:
From the question,
First term = a = 4
Fifth term = a+(n-1)d = a+(5-1)d = a+4d = 24
Since a + 4d = 24
We slot on the value of a
a + 4d = 24
4 + 4d = 24
4d = 24 - 4
4d = 20
d = 20/4
d = 5
The term to term rule will be "add 5"
The arithmetic sequence will be:
4
4+5 = 9
9+5 = 14
14+5 = 19
19+5 = 24
The inverse of a conditional statement is "If a number is negative, then it has a negative cube root."
What is the contrapositive of the original conditional statement?
If a number is negative, then it does not have a negative cube root.
O If a number does not have a negative cube root, then the number is not negative.
O If a number has a negative cube root, then the number is negative.
O If a number is not negative, then it does not have a negative cube root.
Answer:
C. If a number has a negative cube root, then the number is negative.
Step-by-step explanation:
took the quiz
The inverse of the conditional statement is " If a number does not have a negative cube root, then the number is not negative. "
What is a conditional statement?A conditional statement is a type of logical statement that expresses a relationship between two propositions or statements. It typically takes the form "if p, then q" where p and q are propositions. The statement "if p, then q" is read as "if p is true, then q is true" or "p implies q".
The truth value of a conditional statement depends on the truth values of its antecedent (p) and its consequent (q). If p is true and q is true, then the conditional statement is true. If p is true and q is false, then the conditional statement is false. If p is false, then the truth value of the conditional statement is irrelevant and it is said to be vacuously true.
Given data ,
Let the statement be represented as A
Now , the inverse of the statement is A'
where A = "If a number is negative, then it has a negative cube root."
Now , the inverse of the conditional statement is
A' = " If a number does not have a negative cube root, then the number is not negative. "
Hence , the inverse is " If a number does not have a negative cube root, then the number is not negative. "

Answer: you will land on tails about 100 times if it is a fair coin
Step-by-step explanation: Hope this helps!
A system equation is-
[tex]\bf\begin{cases} & \bf x^4y^5+x^5y^4=810 \\ & \bf x^6y^3+x^3y^6=945 \end{cases}[/tex]
Solve for real x and y .
How to solve it? Please explain. The question is correct.
Answer:
Solution:Given that,
x⁴y⁵ + x⁵y⁴ = 810
➝ x⁴y⁴(x+y) = 810 ---(1)
[tex] \: [/tex]
Further given that,
x⁶y³ + x³y⁶ = 945
x³y³(x³y³) = 945
[tex] \: [/tex]
We know,
[tex] { \boxed{{x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2}) }}[/tex]
So, using this identity, we get,
➝ x³y³( x + y )( x² - xy + y²) = 945
---(2)
[tex] \: [/tex]
On dividing equation (1) and (2), we get,
[tex] \longrightarrow\frac{ {x}^{2} - xy + {y}^{2} }{xy} = \frac{945}{810} [/tex]
[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} - 1 = \frac{7}{6} [/tex]
[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} = \frac{7}{6} + 1[/tex]
[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} = \frac{7 + 6}{6} [/tex]
[tex] \longrightarrow \: \frac{ {x}^{2} + {y}^{2} }{xy} = \frac{13}{6} [/tex]
[tex] \: [/tex]
➝ 6x² + 6y² = 13xy
➝ 6x² - 13xy + 6y² = 0
➝ 6x² - 4xy - 9xy + 6y² = 0
➝ 2x( 3x - 2y ) - 3y( 3x - 2y ) = 0
➝ ( 3x - 2y ) ( 2x - 3y ) = 0

[tex] \: [/tex]
[tex]{ \underline {\underline {\red{Case:- 1 }}}}[/tex]
[tex]{ \bold{When \: x = \frac{3y}{2}}} [/tex]
In Substating the value of x in equation (1) we get,
[tex] \frac{81 {y}^{4} }{16} \times {y}^{4} \times ( \frac{3y}{2} + y) = 810[/tex]
[tex] \frac{ {y}^{8} }{16} \times ( \frac{5y}{2} ) = 10[/tex]

Range of all y values less than 0turn b to Euler's number thenAs we know that e^x has range (0,oo) when multiplied with any negative number i.e here -3 it yields y less than 0[tex]\\ \rm\rightarrowtail y=-3e^x[/tex]
Graph attached
Answer:
General form of an exponential function: [tex]y=ab^x[/tex]
where:
[tex]a[/tex] is the y-intercept (or initial value)[tex]b[/tex] is the base (or growth factor)[tex]x[/tex] is the independent variableIf [tex]b > 1[/tex] then it is an increasing function
If [tex]0 < b < 1[/tex] then it is a decreasing function
Also [tex]b\neq 1[/tex]
Given:
y-intercept = (0, -3)[tex]\implies y=(-3)b^x[/tex]
If we want the function to be decreasing, then as [tex]a[/tex] is negative, we need [tex]b > 1[/tex] to make the overall function decreasing.
Let [tex]b=2[/tex] :
[tex]\implies y=(-3)2^x[/tex]
If we want the function to be increasing, then as [tex]a[/tex] is negative, we need [tex]0 < b < 1[/tex] to make the overall function increasing.
Let [tex]b=\dfrac12[/tex] :
[tex]\implies y=-3\left(\dfrac12\right)^x[/tex]
However, it doesn't matter whether the function is increasing or decreasing as the range of both of the above given functions is < 0 as [tex]a[/tex] is negative and [tex]b[/tex] is positive.

Angle r° = 2w°. What is the measure of angle r°? please helppp
120°
240°
286°
143°
Answer:
so involved triangles we know that one angle is 90° because of the right angle sign and you know that two x two interior angles add up to 180 angle so 90 degrees we will name the unknown angle x + x is equals to 127 degrees x is equals to 37 degrees so we have two angles are both of the triangles that is 90 degrees and 37 degrees 37 degrees is on the upper part of the triangle so it'll be 37° + 37° to get 74 degrees and the angle that you're looking for is a reflex angle so it'll be 360 degrees - 74 degrees so they think the answer is 286 degrees

Step-by-step explanation:
Triangle XYZ, with vertices X(-2, 0), Y(-2, -1), and Z(-5, -2), undergoes a transformation to form triangle X′Y′Z′, with vertices X′(4, -2), Y′(4, -3), and Z′(1, -4). The type of transformation that triangle XYZ undergoes is a (1: translation 2 units left and 6 units up, 2: Reflection across the y-axis, 3: Reflection across the x-axis, 4: Translation 6 units right and 2 units down, 5: Dilation by scale factor 2. Choose the Correct answer.
Answer:
4. Translation 6 unit right and 2 units down.
Step-by-step explanation:
Let' take the point and it's corresponding image.
x(-2,0) and x'(4,-2)
Now,let's find the translation
-2+? =4
0+? =-2
Now, if we solve each for ?, we get
-2+?=4, gives ? =6
0+?=-2 gives ?=-2
It means the translation is move right 6 units and down 2 units.
So, option 4 is right.

What is the margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
A simple random sample of 90 is drawn from a normally distributed population, and the mean is found to be 138, with a standard deviation of 34.
The 90% confidence interval for the population mean. Then we have
[tex]\rm Margin \ of \ error = z * \dfrac{Standard \ deviation}{\sqrt{sample \ size}}\\\\\\\Margin \ of \ error = 1.645 * \dfrac{34}{\sqrt{90}}\\\\\\Margin \ of \ error = 5.9[/tex]

Answer:
-5x² + 2x + 3
Step-by-step explanation:
Since its a trinomial, it has three terms.
Since it has a degree 2, the highest degree is 2 and will usually be the first term.
The coefficient of the first term must have a -5.
Standard form is like ax² + bx + c
Where a,b, and c are variables.
So, -5x² + 2x + 3 should work
We know the standard form
ax^2+bx+c=0Now
a=-5So the expression is given by
-5x^2+3x+8=0Riddle

How to solve 7 + 13n - 1 > 5 ( 2n + 2 ) + 8 by two step inequality
Answer:
n>4
Step-by-step explanation:
1. Let's first simplify each sides.
7 + 13n − 1 > 5(2n+2) + 8
a. 7 - 1
Distribute the 5.
b. 5 x 2n = 10n
5 x 2 = 10
c. 10n + 10 + 8 = 10n + 18
13n + 6 > 10n + 18
2. Now, eliminate 10n on both sides, as there can't be 2 variables on the opposite sides.
13n + 6 > 10n + 18
-10n -10n
a. 3n + 6 > 18
3. Subtract 6 from each side.
3n + 6 > 18
-6 -6
a. 3n > 18
Divide 3
b. n > 4

solve the system of linear equations -x+4y=-8 -1/4x+y=-1
Answer:
(- 2, - 6)Step-by-step explanation:
Given system:
x + 4y = -8 -1/4x + y = -11. Multiply the second equation by - 4 to get:
(- 4)(-1/4x + y ) = (- 4)(- 1)x - 4y = 42. Now, add this up with the first equation:
x + 4y + x - 4y = - 8 + 42x = - 4x = - 23. Find the value of y:
- 2 + y = - 8y = - 8 + 2y = - 6The solution is (- 2, - 6)
