The factored expression of 56r + 7 is 7(8r + 1)

The expression is given as

56r + 7

Express 56 as the product of 8 and 7

So, we have'

56r + 7 = 7 * 8r + 7

Express 7 as the product of 7 and 1

So, we have'

56r + 7 = 7 * 8r + 7 * 1

Factor out 7 from the expression

56r + 7 = 7(8r + 1)

Hence, the factored expression of 56r + 7 is 7(8r + 1)

The median is 16.

Step-by-step explanation:

To find the median of a set, first we sort the set in an incresing way. So

3,5,8,11,15,16,18,22,23,32,36

The set has 11 elements, so the median will be element at the position (11+1)/2 = 6, that is, the 6th element of the sorted set.

In this case, the median is 16.

(1) The value of x is determined as 16.8.

(2) The measure of length VX is calculated as 4.1.

(3) The measure of angle UWV is 69.5⁰.

The value of the missing lengths of the triangle is calculated by applying the following formula;

(1) For the two similar triangles, the value of x is calculated as follows;

20 / (28 - x) = 30 / x

20x = 30 (28 - x )

20x = 840 - 30x

20x + 30x = 840

50x = 840

x = 840 / 50

x = 16.8

(2) The measure of length VX is calculated by applying trig ratios.

tan 63 = 8 / VX

VX = 8 / tan 63

VX = 4.1

(3) The measure of angle UWV is calculated as follows;

angle T = 360 - (94 + 127) = 139

angle UWV = ¹/₂ x 139 (angle at circumference is half of angle at center)

angle UWV = 69.5⁰

Anna will make  $1602.71 in all over 10 weeks.

Here, the first week salary of Anna = $116

i.e., the initial salary a =  $116

She was guaranteed a raise of 7% each week.

so, her salary in the next week would be,

116 + 7% of 116

7 percent of 116 is:

116 × 7/100 = 8.12

so, her salary will be $124.12

So, the equation for the salary after 'm' weeks would be,

\(n = 116\times (1 + 0.07)^{m - 1}\\\\n = 116\times (1 .07)^{m - 1}\)

Using this equation , the salary in the second week m = 2 would be,

n = 124.12

Salary in the third week m = 3 would be,

n = 116 × \((1.07)^{3-1}\)

n = 132.81

Salary in the fourth week m = 4 would be,

n = 116 × \((1.07)^{4-1}\)

n = 142.11

Salary in the fifth week m = 5 would be,

n = 116 × \((1.07)^{5-1}\)

n = 152.05

Salary in the sixth week m = 6 would be,

n = 116 × (1.07)⁶⁻¹

n = 162.7

Salary in the seventh week m = 7 would be,

n = 116 × (1.07)⁷⁻¹

n = 174.08

Salary in the eighth week m = 8 would be,

n = 116 × (1.07)⁸⁻¹

n = 186.27

Salary in the nineth week m = 9 would be,

n = 116 × (1.07)⁹⁻¹

n = 199.31

And the salary after the tenth week m = 10 would be,

n = 116 × (1.07)¹⁰⁻¹

n = 213.26

The total money after 10 weeks would be,

T = 116 + 124.12 + 132.81+ 142.11 + 152.05 + 162.7 + 174.08 + 186.27 + 199.31 + 213.26

This question is incomplete, the complete question is;

A general reaction written as A + 2B → C + 2D is studied and yields the following rate law: ∆A/∆t = k A².

The initial concentration is 1.000 M and t½=20.00 s.

How long will it take for the concentration to reach 0.0500 M

Answer:

it will take 380 seconds for the concentration to reach 0.0500 M

Step-by-step explanation:

Given that;

A + 2B → C + 2D

initial concentration A₀ = 1 M

half life t1/2 = 20sec

concentration after t time [A_t] = 0.0500 M

∆A/∆t = k A²

This is a second order chemical kinetics

for this order; t1/2 = 1 / [A]₀K

A₀ is initial concentration, K is rate constant, t1/2 is half life

so,

k = 1 / [A₀]t1/2

we substitute

K = 1 / 1.000 × 20

K = 0.05 mol⁻¹L/sec

for second reaction order

1/[A_t] = kt + 1/[A₀]

kt = 1/[A_t] - 1/[A₀]

we substitute

kt = 1/0.0500 - 1/1.000

kt = 20 - 1

kt = 19

substitute the value of k

0.05 × t = 19

t = 19 / 0.05

t = 380 sec

Therefore it will take 380 seconds for the concentration to reach 0.0500 M

Answer:

\(t = 11.085\)

Step-by-step explanation:

The expression is given as:

\(h=-16t^2+24t+1700\)

Required

Determine how long it will hit the ground

When the pebble is on the ground, this implies that h = 0

So, we have that:

\(h=-16t^2+24t+1700\) becomes

\(0=-16t^2+24t+1700\)

Reorder

\(-16t^2+24t+1700 = 0\)

Multiply through by -1

\(16t^2-24t-1700 = 0\)

Solve using quadratic formula \(ax^2 + bx + c = 0\):

\(t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}\)

Where

\(a = 16\)   \(b = -24\)    \(c = -1700\)

So, we have:

\(t = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}\)

\(t = \frac{-(-24) \± \sqrt{(-24)^2 - 4*16*(-1700)}}{2*16}\)

\(t = \frac{24 \± \sqrt{576 + 108800}}{32}\)

\(t = \frac{24 \± \sqrt{109376}}{32}\)

\(t = \frac{24 \± 330.72}{32}\)

\(t = \frac{24 + 330.72}{32}\) or \(t = \frac{24 - 330.72}{32}\)

\(t = \frac{354.72}{32}\) or \(t = \frac{-306.72}{32}\)

\(t = 11.085\) or \(t = -9.585\)

But time can't be negative.

So: \(t = 11.085\)

Hence, it will take 11.085 seconds to hit the ground

7(3x-4) = 6x -4 +3x +12​

Distributing:

7(3x) -7(4) = 6x -4 +3x +12​

21x - 28 = 6x -4 +3x +12​

Combining similar terms:

21x - 28 = (6x + 3x) + (-4 +12​)

21x - 28 = 9x + 8

9x is adding on the right, then it will subtract on the left

28 is subtracting on the left, then it will add on the right

21x - 9x = 8 + 28

12x = 36

12 is multiplying on the left, then it will divide on the right

x = 36/12

Answer:

\( \angle R < \angle S < \angle Q\)

Step-by-step explanation:

In ΔQRS, RS = 16, SQ = 9, and QR = 15.

From above info it is obvious that:

SQ < QR < RS

In a triangle, angle opposite to smallest side is smallest and angle opposite to largest side is largest.

Therefore,

\( \angle R < \angle S < \angle Q\)

The system has an infinite number of solutions, but the only solution is (a, b) = (0, 0).

The given system of equations can be solved using the substitution method. We can begin by solving the first equation,\(a^2 + b^2\), for either a or b. Let's solve for a:

\(a^2 + b^2 = 0\)

\(a^2 + b^2 = 0\)

\(a^2 = -b^2\)

\(a = \pm\sqrt(-b^2)\)

We can substitute this expression for a into the second equation, \(3a^2 - 2ab - b^2 = 0\), and simplify:

\(3(\pm\sqrt(-b^2))^2 - 2(\pm\sqrt(-b^2))b - b^2 = 0\)

\(3b^2 - 2b^2 - b^2 = 0\)

0 = 0

Since 0 = 0, this means that the system of equations has an infinite number of solutions. In other words, any values of a and b that satisfy the equation \(a^2 + b^2 = 0\) will also satisfy the equation \(3a^2 - 2ab - b^2 = 0\)

However, the equation \(a^2 + b^2 = 0\) only has a single solution, which is a = b = 0. Therefore, the solution to the system of equations is (a, b) = (0, 0).

The true statement about the function is C. function f and function g are not inverse because f{g(x)} = g{f(x)} .

An inverse function or an anti function, which can reverse into another function.In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f-1 or F-1.

now the given functions are,

f(x) = √(2x + 2) and

g(x) = (x^2 -2)/2

Now,

f{g(x)} = f{(x^2 -2)/2}

         = √(2(x^2 -2)/2 + 2)

         = √ x^2 -2 + 2

f{g(x)} = √ x^2

f{g(x)} =  x

Now,

g{f(x)} = g{ √(2x + 2)}

         = (√(2x + 2)^2 -2)/2

         = (2x + 2) -2 /2

         = 2x/2

f{g(x)} = x

Here we see that ,

f{g(x)} = g{f(x)}

Hence f and g are not inverses.

∴The true statement about the function is C. function f and function g are not inverse because f{g(x)} = g{f(x)} .

The length AC in the kite is 8.7 cm.

A kite is a quadrilateral that has two pairs of consecutive equal sides and

perpendicular diagonals. Therefore, let's find the length AC in the kite.

Hence, using Pythagoras's theorem, let's find CE.

Therefore,

7² - 4² = CE²

CE = √49 - 16

CE = √33

CE = √33

Let's find AE as follows:

5²- 4² = AE²

AE = √25 - 16

AE = √9

AE = 3 units

Therefore,

AC = √33 + 3

AC = 5.74456264654 + 3

AC = 8.74456264654

Step-by-step explanation:

If Darnel took a total of 8 quizzes over the past 2 weeks. We can assume that he takes 4 quizzes in one week but that doesn't matter. If he attended 4 weeks of school he would have taken 16 quizzes because in 2 week he takes 8 quizzes, so 8+8=16. Each 8 represents 2 weeks.

Answer:

  (d)  (1, 2)

Step-by-step explanation:

You want to know which of the given points satisfies the inequality.

We find it easiest to plot the given points on a graph of the solution. This shows us that (1, 2) is a solution to the inequality. (It lies in the solution area.)

__

Additional comment

Another way to choose the answer is to try each of the points in the inequality.

If you can visualize the boundary line (without plotting it) as a line with positive slope and a y-intercept of 2, you can more readily reject the first choice and accept the last choice. (0, 3) is above the y-intercept, and (1, 2) is to the right of it (in the solution space).

You may also recognize the x-intercept will be -3, so the second choice lies above the boundary line.
