Answer:

Caleb’s error was :

instead of selecting the least exponent ,Caleb took the highest exponent.

Step-by-step explanation:

3x² = 3 • x • x

(in this factorization the exponent of 3 is 1 and the exponent of x is 2)

9x = 3 • 3 • x

(in this factorization the exponent of 3 is 2 and the exponent of x is 1)

• The common factors of 3x² and 9x are 3 and x

In order to determine the GCF ,we have to Compare the exponents of the  common factors then take the numbers which have the least exponent value.

• in the factorization of 3x² the exponent of 3 is 1

and in the factorization of 9x the exponent of 3 is 2

The least exponent is 1 Then we take it.

• in the factorization of 3x² the exponent of x is 2

and in the factorization of 9x the exponent of x is 1

The least exponent is 1 Then we take it.

Conclusion:

GCF(3x² , 9x) = 3¹ × x¹ = 3x

The truth of the given function that we have here is  The function increases at a constant multiplicative rate.

The table is given as

x            0   1    2      3

f(x)         2   3   4.5   6.75

We have x ranging from 0 to 3 while y ranges from 2 to 6.75.

The observations that we can make about the y values is that they produce the next value at the same rate of multiplication.

This is shown here

2 x 1.5 = 3

3 x 1.5 = 4.5

4.5 x 1.5 = 6.75

Hence we can conclude that it increases at a constant multiplicative rate of 1.5.

A table representing the function f(x) = 2(three-halves) Superscript x is shown below. A 2-column table has 4 rows. The first column is labeled x with entries (0, 1, 2, 3). The second column is labeled f (x) with entries 2, 3, 4.5, 6.75. What is true of the given function? The function increases at a constant additive rate. The function increases at a constant multiplicative rate. The function has an initial value of 0. As each x value increases by 1, the y values increase by 1.

Answer:

52.9%

Step-by-step explanation:

There are 17 shapes total. Nine of those shapes are triangles. Therefore the probability of choosing a triangle is 9/17.

To find that as a percentage type 9 divided by 17 into the calculator. The answer to that is 0.5294117647058824. To turn a decimal into a percentage move the decimal point two places over making the percentage: 52.94117647058824%.

Since the yellow text states to round the answer to the nearest hundredth of the percent the answer is 52.9%.

52.94%

Step-by-step explanation:

there are 17 objects and you divide the 9 triangles by 17 and get .529411765. Which is 52.94 percent.

Frogs are at the pond = 12.

Given,

There are some frogs and some lily pads at a pond. If lily pads with frogs on them have two frogs each, then there are 3 lily pads with no frogs on them. If each lily pad has exactly one frog on it, then there are 3 frogs with no lily pad.

= 2( n-3) = n+3

= 2n -6 = n+3

=> n = 9

9 pads, 12 frogs.

Step-by-step explanation:

Area of a triangle = 1/2 × base × height

Use the distance between two points formula to find the measure of the height and base of ΔXYZ.

Distance between two points

Answer:

(i) Total cost of the flat is Rs. 540000.

(ii) Expenditure incurred on labour is Rs. 150000

Step-by-step explanation:

According to the question, cement cost is Rs. 112500, which represents 75° in the pie chart.

(i) The total cost of the flat is represented by the total 360° in the pie chart.

∴ Using unitary method

75° represents Rs. 112500

⇒ 360° represents = [tex]\frac{112500}{75}[/tex]  ×  360

                                = Rs. 540000

∴  Total cost of flat = Rs. 540000

(ii) Similarly, to calculate the cost of labour, represented by 100° in the pie chart, we can use the unitary method:

75° represents Rs. 112500

⇒ 100° represents =  [tex]\frac{112500}{75}[/tex]  ×  100

                               = Rs. 150000

∴ Cost of labour = Rs. 150000

The maximum height of the rocket is 78.4m

Given the function that represents the height of a function expressed as:

h(t) = -4.9t² +9.8t + 73.5.

The rocket will reach its maximum height at the point where h'(t) = 0

h'(t) = -9.8t +9.8

Equate to zero

0 = -9.8t + 9.8

9.8t = 9.8

t = 1

Substitute

h(1) = -4.9(1)²+9.8(1) + 73.5

h(1) = 4.9 + 73.5

h(1) = 78.4m

Hence the maximum height of the rocket is 78.4m

Answer:

16

Step-by-step explanation:

let x be a positive integer

mathematically, the statement: “The product of two consecutive positive integers is 194 more than the next integer” means  x(x + 1) - 194 = x + 2

………………………………

Solving the equation x(x + 1) - 194 = x + 2 for x :

x(x + 1) - 194 = x + 2

⇔ x² + x - 194 = x + 2

⇔ x² - 194 = 2

⇔ x² = 196

⇔ x = 14 or x = -14

Since -14 < 0 then the solution to our equation is x = 14

Therefore

The largest integer of the three is x + 2 = 14 + 2 = 16

Verification:

14 × 15 − 194 = 210 − 194 = 16

The x intercept is ( 7π/12 , 11π/12 , 19π/12 ,23π/12) , Option B is the correct answer.

The x intercept is the point at which the function intersects the x axis , the point at which y = 0

The given function is

g(x) = 2sin2x +1

g(x) = 0 , for x intercept

2sin2x +1 = 0

sin 2x = -1/2

Here we have:

-3 < y - 7x < 15

Isolating y, we get:

-3 + 7x < y < 15 + 7x

So we need to graph two linear inequalities:

y > -3 + 7x

y < 15 + 7x

So we need to graph two parallel lines (with dashed lines, the lines aren't solutions) and shade the region above the first line and below the second line.

$194.97 is the cost of the credit loan.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

The total cost of the dishwasher with sales tax can be found by multiplying the price by 1.04:

$1249.99 × 1.04 = $1299.99

The cost of credit is the total amount paid through the installment loan minus the cost of the dishwasher:

12 × $124.58 = $1494.96

$1494.96 - $1299.99 = $194.97

By the Congruent Supplements Theorem, we can conclude that,

∠FBC ≅ ∠DBG.

What is Congruent Supplements Theorem?

The Congruent Supplements Theorem states that two angles are said to be congruent if they are supplements of the same angle or even congruent angles.

If there are 4 lines such that, right angles are created when a horizontal line with the points F, B, and G crosses a vertical line with the points A, B, and E at point B. Between angles F and B and A and G, a third diagonal line with the points D, B, and C is intersecting the other two lines at point B. At points A, C, and G, there is a fourth line that joins three other lines.

Drawing Conclusion

In case the angle FBC and angle CBG are supplementary angles, angle DBG and angle DBF are another pair of supplementary angles, and angle CBG is-congruent-to angle DBF, we can apply congruent supplement theorem and draw the following inference,
