If x>-1, which number could be a value of x? O A. -1 O B. -7 O c. 1 O D.-13​

Answer:

No

Step-by-step explanation:

These two triangles cannot be proven similar as there is only 1 angle which is shared between the two, that being: HMG=JMK since they are vertically opposite angles.

To prove 2 triangles are similar we need at least 2 equal angles.

+ Note that no equal sides are shared by the triangles.

The water level of a pond falls 3 1/3 feet below its normal level.

Step-by-step explanation:

The water level of a pond is 2 feet below its normal level.

The water level of the pond dropped another 1 1/3 feet.

So the total level dropped is 2 + 1 1/3

= 2 + 4/3

= 6+4/3= 10/3 = 3 1/3 feet below the normal.

Suppose the normal is at zero then the level of the pond is at the end of the summer is 0 - 3 1/3 = - 3 1/3 feet.

If we represent the normal by x then the equation becomes

x- 3 1/3 feet  to show the water level at the end of summer.

Or it can also be written as

x - (  2 + 1 1/3)

Using the normal distribution, Joshua's score is communicated as being in the 84th percentile.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 78, \sigma = 10[/tex].

He scored 88, hence X = 88 and his z-score is of:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{88 - 78}{10}[/tex]

[tex]Z = 1[/tex]

[tex]Z = 1[/tex] has a p-value of 0.84.

Hence, Joshua's score is communicated as being in the 84th percentile.

Answers to 1 and 5:
Q1 Angle 1: 129 degrees

Q1 Angle 2:116 degrees
Q5 Angle 1: 143 degrees

Q5 Angle 1: 78 degrees

Step-by-step explanation:

I cannot solve all of these, however I can still solve some of them. We know that one side of a straight line is 180 degrees.

Question 1:

If the angle that is next to angle 1 is 51 degrees, then we simply do: 180-51. The result will be 129 degrees.

The angle next to angle 2 is 64. 180-64= 116 degrees.

Question 5:

The angle next to angle 1 is 37. 180-37= 143 degrees.

The angle next to angle 2 is 102. 180-102=78 degrees.

The value of the rational function f(x) (x³ + 3x)/(x + 10) on putting the value of x of 5 is 9.3333.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function f is given below.

[tex]f(x ) = \dfrac{x^3 + 3x }{x+ 10}[/tex]

Then the value of f(x) at x = 5 will be given as

[tex]\rm f(x ) = \dfrac{5^3 + 3*5 }{5+ 10}\\\\\\f(x ) = \dfrac{125 + 15}{15}\\\\\\f(x ) = \dfrac{140}{15}\\\\\\f(x) = 9.333[/tex]

Answer:

2^(n-1)

Step-by-step explanation:

To find the nth term of the sequence 1, 2, 4, 8, 16, 32, 64,..., we can observe that each term is obtained by multiplying the previous term by 2. Therefore, the pattern can be described by the formula:

nth term = 2^(n-1)

In this formula, n represents the position of the term in the sequence.

For example: I

If we want to find the 5th term, we substitute n = 5 into the formula:

5th term = 2^(5-1) = 2^4 = 16

So, the 5th term of the sequence is 16.

Latoya created a factor tree and wrote the prime factorization of 90 shown below.

A factor tree of 90. 90 branches to 9 and 10. 9 branches to 3 and 3. 10 branches to 2 and 5. The equation is 90 = 2 times 3 times 5.

What is Latoya’s error?

She should not have found the factors of 9.

She should have included an exponent of 2 on the 3.

She should have included 9 and 10 in the prime factorization.

She should have started the tree with 2 times 45.

The formula to represent the remaining value of the card is aₙ = 26.5 - 1.5n

The value of the card after ten downloads is $10

aₙ = a + (n - 1)d

where

a = first term

d = common difference

n = number of terms

Therefore,

a = 25

d = 23.5  - 25 = - 1.5

Therefore,

aₙ = 25 + (n - 1)(-1.5)

aₙ = 25 - 1.5n + 1.5

aₙ = 26.5 - 1.5n

After ten download the value of the card will be as follows,

26.5 - 1.5(11) = 26.5 - 16.5 = $10

I solved the equation 40/100×127

Answer:

The very first thing we want to do in this equation is to isolate x on one side (preferably the left side).

3/x - 4 = 1/5

We get rid of any constants first, by performing the inverse property;

The inverse property of subtraction is addition, so we add 4 to both sides:

+4        +4

3/x = 4 1/5

3 is being divided by x, so the inverse operation of division is multiplication. So we multiply by 1/3 on both sides.

x1/3    x1/3

X = 1 4/10 which simplifies to 1 2/5.

The simplified product is 2x³ + 5x² - x - 6.

Option C is the correct answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(2x + 3) (x² + x - 2)

(2x)(x²) + (2x)(x) + (2x)(–2) + (3)(x²) + (3)(x) + (3)(–2)

2x³ + 2x² - 4x + 3x² + 3x - 6

2x³ + 5x² - x - 6
