Answer: x = 2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

Given equation,

→ 5(2x + 1) = 25

Solving for the value of x,

→ 5(2x + 1) = 25

→ 10x + 5 = 25

→ 10x = 25 - 5

→ x = 20/10

→ [ x = 2 ]

Hence, the value of x is 2.

The face of the rhombus ( length of one side) is found to be 13 cm.

A rhombus is a special parallelogram because it meets the definition of a parallelogram, which is a quadrilateral to two pairs of parallel sides.

As per the given question;

The circumference of the rhombus is 52 cm.

Let us consider the one side of the rhombus is of length 'x'.

As, we known that the sides of the rhombus are equal.

Thus,

4x = 52

x = 52/4

x = 13.

f(g(-3)) = f(6) = 9.

For composing functions like this, we'll work from the inside out. First, find g(-3) by plugging x = -3 into the function g(x):

g(x) = |x - 3|

g(-3) = |-3 - 3|

g(-3) = |-6|

g(-3) = 6

Now we can replace g(-3) with 6 in the function composition to get f(g(-3)) = f(6). Find f(6) by plugging x = 6 into the function f(x):

f(x) = x + 3

f(6) = 6 + 3

f(6) = 9

So, f(g(-3)) = f(6) = 9.

Answer:

80 (Estimate, we'll get to the exact result at the end.)

Step-by-step explanation:

[tex]\mathrm{(Round)~If~x < 5,~x=y.0}[/tex]

→ y is the number, for instance, 60.0 since 63.0 in the ones/tenths place is less than 5 or 0.5

[tex]20 \times 70 = 1,400[/tex]

→ imagine the newly rounded 73 as 2 × 7 which is 140, but it's 2 more 0's, so it's 1,400.

[tex]\bold{77}\\18|1,400\\18 \times 7 = 126\\140 - 126 = 14\\18 \times 7 = 126\\140 - 126 = 14[/tex]

→ long division was performed. for each time a 0 appeared in 14 when 140 was subtracted by 126(18 • 7), a zero was either borrowed from 1,400 or dropped from 1,400 which became our remainder of 14 both ways around.

→ 77 is close to 75 but not below 5, so it round to 80. therefore, your estimate result is 80.

The equation of the circle where the given parameters are Center = (6, 15) and Radius = 2 is (x - 6)^2 + (y - 15)^2 = 4

The given parameters are

Center = (6, 15)

Radius = 2

Rewrite the above parameters properly as

Center, (h, k) = (6, 15)

Radius, r = 2

The equation of the circle is represented as

(x - h)^2 + (y - k)^2 = r^2

Substitute the known values in the above equation

So, we have

(x - 6)^2 + (y - 15)^2 = 2^2

Evaluate the exponent of 2

So, we have

(x - 6)^2 + (y - 15)^2 = 4

Hence, the equation of the circle where the given parameters are Center = (6, 15) and Radius = 2 is (x - 6)^2 + (y - 15)^2 = 4

Answer:   [tex]2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}[/tex]

===========================================================

Explanation:

The first term is [tex]a_1 = 2\text{x}[/tex] and the common ratio is [tex]r = \text{x}^3[/tex]

To get the second term, we multiply the first term by that common ratio

[tex]a_2 = a_1*r = 2\text{x}*\text{x}^3 = 2\text{x}^4[/tex]

Repeat a similar idea for the third term

[tex]a_3 = a_2*r = 2\text{x}^4*\text{x}^3 = 2\text{x}^{4+3} = 2\text{x}^7[/tex]

and the fourth term is

[tex]a_4 = a_3*r = 2\text{x}^7*\text{x}^3 = 2\text{x}^{7+3} = 2\text{x}^{10}[/tex]

The fifth term is

[tex]a_5 = a_4*r = 2\text{x}^{10}*\text{x}^3 = 2\text{x}^{10+3} = 2\text{x}^{13}[/tex]

Something to notice: The exponents of the first five terms are: 1, 4, 7, 10, 13. The sequence of exponents is arithmetic even though the original underlying sequence is geometric.

The reason why the exponent sequence is arithmetic is because we keep multiplying by [tex]\text{x}^3[/tex], and hence we keep adding 3 to each exponent to get the next exponent.

-----------------------------------------

To summarize, the first five terms are:

[tex]2\text{x}, \ 2\text{x}^4, \ 2\text{x}^7, \ 2\text{x}^{10}, \ 2\text{x}^{13}[/tex]

We will ignore the first term 2x since your teacher wanted you to find the next four terms after that first term (i.e. term2 through term5).

The number of years for which the money was invested is 5.0 years

From the question, we are to determine how long (in years) the money was invested

From the given information,

Lina invested $7,800 at a simple interest rate of 4.35%

and

She earned $1,696.50 in interest

From the formula for simple interest

I = PRT

Where I is the simple interest

P is the principal

R is the rate

and T is the time in years

From the given information,

I = $1,696.50

P = $7,800

R = 4.35% = 0.0435

Thus,

1696.50 = 7800 × 0.0435 × T

1696.50 = 339.3 × T

T = 1696.50/339.3

T = 5.0 years

The surface area needed to be paint is 3,008 sq. ft. The cans requires for the paint are 15.

A cuboid is a 3 solid with six (rectangular) faces, eight vertices, and twelve edges.

Total Surface Area (TSA) = 2(lb + bh + hl) sq.units

where, i is the length, b is the breadth and h is the height.

The given values are;

length l = 12 ft

breadth b = 10 ft

height h = 16 ft

Put the values in the formula;

Total Surface Area (TSA) = 2(12×10 + 10×16 + 16×12)

                                         = 2×(120 + 160 +192)

                                          = 2×(472)

Total Surface Area (TSA) = 1504

Now, reduce the area of the floor as it is not to be painted;

Painted area = Total Surface Area (TSA) - area of floor

                     = 1504 -12×10

Painted area = 3,008 sq. ft

The area covered by 1 paint can is 200 sq. ft.

Can required = total painted area/painted area by one can

Can required = 3,008/200

                      = 14.44

Can required = 15 (as half can is not considered)

Since their dot product is not equal to zero, then (8,-4) and (-2,4) are not normal to each other.

Two vectors are said to be normal or perpendicular to each other if the result of their dot product is equal to zero.

These two vectors are also called orthogonal to each other.

Let u = (u₁, u₂) and  v = (v₁, v₂), then the dot product u . v is defined as:

u . v = u₁v₁ + u₂v₂

To check whether the vectors are normal to each other, let us check their dot product.

The given vectors are: (8,-4) and (-2,4)

Let u = (8,-4) and  v = (-2,4), then,

u . v = 8 . (-2) + (-4) . 4

y<=x^2-3 is the graph of the function. The vertex of the graph is (0, -3), so when x=0, y=-3. Also, for every x-coordinate, the shaded region is below the corresponding y-coordinate. For example, when x=0, the shaded area for that x-coordinate is below y=-3.

The value of -4(7/10) - 9(7/15) is -85 / 6.

A fraction represented with its quotient and remainder is a mixed fraction.

For example:

3 4/5 is a mixed fraction, where 3 is the quotient, and 4 is the remainder.

We have,

-4(7/10) - 9(7/15)

Convert each term into a proper fraction.

4 7/10 = (40+7) / 10 = 47 / 10

9 7/15 = (135 + 7) / 15 = 142 / 15

Now,

= -47 / 10 - 142 / 15

The LCM of 10 and 15 is 30

= [3 x (-47) - (2 x 142)] / 30

= (-141 - 284) / 30

= -425 / 30

We can divide by a common factor of 5

= - 85 / 6

Thus the value of -4(7/10) - 9(7/15) is -85 / 6.

Answer:

Thabo had 51 crayons at the start.

Step-by-step explanation:

Sam has three times as many crayons as Thabo. Then

x = 3y.

If Sam gives 17 crayons to Thabo, then he will have twice as many crayons as Thabo. Then

(x-17) = 2(y+17).

Thabo had 51 crayons to start with.

Given that Sam has three times more crayons than Thabo does. He will have twice as many crayons as Thabo if he gives him 17 of them.

We need to determine the number of crayons Thabo had in starting.

Let's use algebra to solve this problem step-by-step.

Let's assume that Thabo starts with "x" crayons.

According to the given information:

Sam has three times as many crayons as Thabo, which means Sam has 3x crayons.

If Sam gives Thabo 17 crayons, he will have (3x - 17) crayons left.

Thabo will have (x + 17) crayons after receiving the 17 crayons from Sam.

Now, the second condition states that if Sam gives Thabo 17 crayons, he will have twice as many crayons as Thabo.

Mathematically, it can be expressed as:

2(x + 17) = 3x - 17

Let's solve this equation to find the value of x:

2x + 34 = 3x - 17

Subtract 2x from both sides:

34 = x - 17

Now, add 17 to both sides:

x = 51

So, Thabo had 51 crayons to start with.
