Answer: The triangle is not possible.

Step-by-step explanation:

1) Find the missing angle

62+59+x=180

x=59

2) Use the Law of Sine to check if the triangle sides are the same.

The Law of sine means that Sine the angle and divide with the side across it will equal to same.

[tex]\frac{sin(x)}{x} =\frac{sin(y)}{y}[/tex]

Substitute the numbers.

[tex]\frac{sin(59)}{10} =\frac{sin(62)}{10}[/tex]

0.0636 = -0.0739

3) Solve

Since the decimals aren't the same, the triangle is not possible.

The given expression (−2)3 x 30 x (−4)(−20) will have the value as -14400

In the above question, the following mathematical expression is given :

(−2)3 x 30 x (−4)(−20)

We need to find the value of the given expression by solving it using the BODMAS rule

According to the rule, first we'll solve the multiplication then subtraction

Therefore, we get

(−2)3 x 30 x (−4)(−20)

(-6) x 30 x (-)(-)80

We know, that (-) x (-) = +

and (-) x (+) = (-)

Therefore, we get

(-6) x 30 x (-)(-)80

(-6) x 30 x 80

-6 x 2400

- 14400

The term in the AP whose value is 201 / 2 is 71.3.

The first term of an arithmetic progression is 5 and the common difference is - 3/2.

The formula of the arithmetic progression can be described as follows:

nth term = a + (n - 1)d

where

Therefore, using the arithmetic progression formula,

a = 5

d = 3 / 2

nth term = 201 / 2

let's find the term(n)

Therefore,

- 201 / 2 = 5 + (n - 1) - 3 / 2

- 201 / 2 = 5  - 3 / 2 n  + 3 / 2

- 201 / 2  - 3 / 2 - 5 =  - 3 / 2 n

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{4.4cm}\underline{Slope Formula}\\\\Slope $(m)=\dfrac{y_2-y_1}{x_2-x_1}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ \\are two points on the line.\\\end{minipage}}[/tex]

Given points:

Substitute the given points into the slope formula to find the slope of the line:

[tex]\implies m=\dfrac{-2-(-1)}{3-4}=\dfrac{-1}{-1}=1[/tex]

[tex]\boxed{\begin{minipage}{5cm}\underline{Point-slope Formula}\\\\$y-y_1=m(x-x_1)$\\\\where $m$ is the slope and\\ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]

Substitute the found slope and the point (4, -1) into the point-slope formula to create the equation of the line:

[tex]\implies y-(-1)=1(x-4)[/tex]

[tex]\implies y+1=x-4[/tex]

[tex]\implies y+1-1=x-4-1[/tex]

The equation in slope-intercept form that represents the situation is y = 5x + 25.

In 3 weeks Ellie she saved $40 and $60 in 7 weeks.

Let x and y represent the number of weeks and the total amount saved respectively.

The equation of a line in slope intercept form is given as:

y = mx + b where m is the slope and b is the y-intercept.

Now when x = 3, y = $40.

Therefore,

y = mx + b

40 = 3m + b                                                                                 --------------(1)

When x = 7, y = $60

y = mx + b

60 = 7m + b                                                                                 -------------(2)

Subtracting (1) from (2),

7m + b - 3m - b = 60 - 40

4m = 20

m = 5

So,

3m + b = 40

3(5) + b = 40

15 + b = 40

b = 25

Hence, the equation of the line in slope intercept form is y = 5x + 25.

The number of red beads that can be obtained from the jar is the ratio of red beads to the total number of beads multiplied by the total number of beads picked at random.

 Number of red beads obtained = (number of red beads / total number of beads) x number of beads picked

Total number of beads = 65 + 154 + 70 = 289

Using simple interest, the rate of interest on the amount that Samantha borrowed to buy the law equipment is 11.75%.

A simple interest system does not accumulate (compound) interest on both the principal and interest, unlike compound interest.

The simple interest uses the following formula, Interest = Principal x Rate x Period.

This simple interest formula can be reversed to find either the principal, rate, or period, as the case may be.

The loan amount = $800

Period of loan  = 9 months

Total interest paid = $70.50

Rate of interest = (Interest × 100)/(Principal × Time)

= 11.75% ($70.50 x 100)/($800 x 9/12)

Interest = $70.50 ($800 x 11.75% x 9/12)

What are Scientific notations?

Scientific notation is a way to display extremely big or extremely small numbers in a more understandable way. We are aware that full numbers can go on forever, but we are unable to write such enormous figures on paper. Additionally, a simpler method of representation was required for the numbers that appear at the millions place following the decimal. This makes it challenging to express a small number of integers in their enlarged form. We thus employ scientific notations. Learn general forms for numbers as well.

Rules for Scientific Notation

We must adhere to the following rule in order to calculate the power or exponent of 10:

The base must always be 10.

Exponents that are non-zero integers must be either positive or negative in order to be used.

The coefficient's absolute value is more than or equal to 1, but it must be less than 10.

Positive and negative numbers, including whole and decimal values, can be coefficients.

The remaining significant digits of the number are represented by the mantissa.

Answer:

5(z² + 7z - 18) = 0

z² + 7z - 18 = 0

(z - 2)(z + 9) = 0

r=−9, s=2

STEPS USING THE DIRECT FACTORING METHOD

5z²+35z−90

This quadratic equation can be resolved using a revolutionary direct factoring technique that does not rely on guesswork. The equation must have the form x2+Bx+C=0 to be solved using the direct factoring approach. To do this, multiply both sides of the equation by 5.

x²+7x−18=0

Let r and s be the factors for the quadratic equation such that x²+Bx+C=(x−r)(x−s) where the sum of factors (r+s)=−B and the product of factors rs=C

r+s=−7

rs=−18

When the average of the two integers is 1/2*-7=-7 /2, the sum of the two numbers r and s are exactly 7. You can also observe that the parabola symbolized by the quadratic equation y=x2+Bx+C has its axis of symmetry in the middle of r and s. An unknown quantity u separates the values of r and s from the center at an equal distance. Describe r and s about the variable u.

r=−7​/2−u

s=−7​/2+u

Put these in the product equation rs=-18 to solve for the unknown quantity u.

(−27​−u)(−27​+u)=−18

Simplify by expanding (a−b)(a+b)=a2–b2

49​/4−u²=−18

Simplify the expression by subtracting 49/4 on both sides

−u2=−18−49​/4=−121​/4

To find the value of the unknowable variable u, simplify the expression by multiplying by 1 on both sides and taking the square root.

u2=121/4

u=±√121/4=±11/2

The factors r and s are the solutions to the quadratic equation. Substitute the value of u to compute the r and s.

r=−7/2−11​/2=−9

s=−7​/2+11​/2=2

Therefore, r=−9, s=2

Answer: 577

Step-by-step explanation:

Answer:

577.0      

Rounded to the nearest 0.1 or

the Tenths Place.

Step-by-step explanation:

576.984

You rounded to the nearest tenths place. The 9 in the tenths place rounds up to 10 because the digit to the right in the hundredths place is 8.

Because the tenths place was rounded up from 9 to 10, the tenths place becomes 0 and the ones place is increased by 1. When a 9 is rounded up to 10, that place value becomes 0 and we add 1 to the previous place value.

577.0

When the digit to the right is 5 or greater we round away from 0.

576.984 was rounded up and away from zero to 577.0

Now, we also know that the equation of the line in general form is given by:

So, the equation of the line will be given by:

So the function is a constant value, thus a horizontal line.

***Explanation for the general form of a line***

The general form of a line is given by:

Here "x" & "y" are two variables; "x1" & "y1" are the component of a point that belongs to that lline and "m" is the slope of that line. We remember that (x1, y1) can be any point that belongs to the line.

So, we simply replace the values, in our case I willl solve for (-2, 1), but we could also use (2, 1), the solution at the end will be the same.
