Answer:

5) A 16(-8)

6) C. 26 + (-5)

7) B. -6°

Step-by-step explanation:

5. A turtle dives towards deeper water at a rate of 8 inches per second. It continues for a total of 16 seconds.

Which expression represents this situation?

We are given Maya's diving rate as:

8 inches per second

Because she is diving, the rate carries a negative sign hence, the expression of the situation is:

16 × -8

= 16(-8)

Option A 16(-8) is correct

6. Marisa has $26 in her purse. She pays $5 for lunch. Which expression represents this situation?

Amount she has =$28

She pays = $5

Hence, $26 + (-$5)

= $26 - $5

Option C. 26 + (-5) is correct

7. Aaron turned on his air conditioning and the temperature in his apartment decreased 6 degrees.

Write an integer to represent the change in temperature.

A decrease or drop in temperature is always expressed as a negative sign. Hence,

Option B. -6° is correct

Answer:

m : ____ $4 ______ - $1

P(m) : __ 0.167 ____ 0.833

Step-by-step explanation:

Given that:

Fair dice is rolled once;

Winning = $4, if output is 6

If otherwise ; winning = - $1

M = amount of money won :

Distribution of M:

The amount of money won (M) is either :

$4 or - $1

Distribution of M:

Possible outcome : {1, 2, 3, 4, 5, 6}

P(winning $4) = P(rolling a 6)

Probability = number of required / number of total possible outcomes

= 1/ 6

P(losing $1) = P(not rolling a 6)

= 1 - P(rolling a 6)

= 1 - 1 /6

= 5/6

m : ____ $4 ______ - $1

P(m) : __ 0.167 ____ 0.833

Answer:

0.599 or 0.6

Step-by-step explanation:

We will be using the alphabets M and N in this solution.

Let M be that one of the number is even

Let N be that the sum is 8

The sample space of these two dice when rolled is 36

Probability of 8 and even numbers is (4,4),(6,2),(2,6)

= 3/36 = 0.08333

Probability of sum of 8 is (4,4),(5,3)(3,5),(6,2),(2,6)

= 5/36 = 0.1389

P(M|N) = 0.08333/0.1389

= 0.599

Answer:

y=2x-2

Step-by-step explanation:

When looking at the line, you can see the y-intercept is at the point (0,2) so it meets the y-axis at that point.  Then, when you look at the pattern between the points on the line, you can see the line has a slope of 2, making the answer y=2x-2

Answer:

Standard error for the sample = $0.12 million

Step-by-step explanation:

Given:

Mean = $3.26 million

Standard deviation = $1.2 million

Number of sample = 100

Find:

Standard error for the sample

Computation:

Standard error for the sample = Standard deviation / √Number of sample

Standard error for the sample = 1.2 / √100

Standard error for the sample = $0.12 million

Answer:

Step-by-step explanation:

The Area of a triangle is expressed as:

A = 1/2 bh

b is the base of the triangle

h is the height of the triangle

Given

dh/dt = 3cm/min

dA/dt = 11cm²/min

height h = 5cm

Area = 10cm²

Get the base first

10 = 1/2b(5)

20 = 5b

b = 20/5

b = 4cm

Differentiating the area with respect to time

A(b, h) = 1/2 bh

According to product rule

dA/dt = 1/2{b dh/dt + h db/dt}

Substitute the given parameters and get db/dt

11 = 1/2{4(3)+5db/dt}

11 = 1/2{12+5 db/dt}

11 = 6 + 5/2 db/dt

11-6 = 5/2 db/dt

5 = 5/2 db/dt

1 = 1/2 db/dt

cross multiply

2 = db/dt

db/dt = 2cm/min

Hence the rate at which the base of the triangle is changing id 2cm/min

Step-by-step explanation:

Divided by 2.

Answer:

the numbers are missing, so I looked for a similar question:

If you copy a document on a machine, you should get a similar copy. suppose you want to reduce a document to 1/6 of its original size, and first reduce it by 25%. By what percent do you need to reduce the copy to obtain the desirable size?

You want the copy to be 1/6 of the original size = 16.67%

Since you first reduced the copy by 25%, the image is now 75% of its original size. In order to finally obtain a copy that is 16.67% of the original size, you must reduce this second copy by 1 - (16.67%/75%) = 77.78% ≈ 78%.

we can check our answer:

size of second copy x (1 - reduction)

0.75 x (1 - 0.7778) = 0.1667

1.7 and 1.700 have the same value because zeros have no value, and without the zeros, 1.700 would turn into 1.7. It is not like there is another number that is not zero after the two zeros either.

Answer:

a, 1.12m

b, P 1257.75

Step-by-step explanation:

A,

9.8m × 4/5 = 7.84m

7.84m ÷ 7 = 1.12m

B,

7 × 178.25 = P1247.75

We are required to find how much cloth she used for each blouse

cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75

Total quantity of geena satin bought = 9.8 meters

Quantity damaged by rat = 1/5 of 9.8 meters

= 0.2 × 9.8

= 1.96 meters

Total cloth used for 7 blouse = Total quantity of geena satin bought - Quantity damaged by rat

= 9.8 meters - 1.96 meters

= 7.84 meters

Cloth used for each blouse = Total cloth used for 7 blouse / 7

= 7.84 / 7

= 1.12 meters

Cost of each blouse = P 178.25

Total cost of 7 blouses = P 178.25 × 7

= P 1247.75

Therefore, cloth used for each blouse is 1.12 meters and total cost of 7 blouses is P 1247.75

Ratio table can help you find equivalent ratios in order to solve problems.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Ratio tables show equivalent ratios between two quantities. You can create a ratio table by multiplying (or dividing) both quantities in the ratio by the same value to find an equivalent ratio.

A ratio table can help you find equivalent ratios in order to solve problems.

Answer:

The equation of a parabola that has a curvature 6 at the origin is [tex]f(x) = 3\cdot x^{2}[/tex].

Step-by-step explanation:

All parabolas are represented by second-order polynomials, whose standard form is:

[tex]f(x) = a\cdot x^{2}+b\cdot x + c[/tex] (Eq. 1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficient of the parabola, dimensionless.

From Vectorial Calculus we know that curvature ([tex]K[/tex]), dimensionless, is defined by the following expression:

[tex]K = \frac{\left|\frac{d^{2}y}{dx^{2}} \right|}{\left[1+\left(\frac{dy}{dx} \right)^{2}\right]^{\frac{3}{2} }}[/tex] (Eq. 2)

Where [tex]\frac{dy}{dx}[/tex] and [tex]\frac{d^{2}y}{dx^{2}}[/tex] are the first and second derivatives of the function, respectively. Each expression is described below:

[tex]\frac{dy}{dx} = 2\cdot a\cdot x + b[/tex]

[tex]\frac{d^{2}y}{dx^{2}} = 2\cdot a[/tex]

If we know that [tex]a > 0[/tex], [tex]b = c = 0[/tex], [tex]x = 0[/tex] and [tex]K = 6[/tex], then the equation of curvature and polynomial are, respectively:

[tex]\frac{2\cdot a}{1^{\frac{3}{2} }} = 6[/tex]

[tex]a = 3[/tex]

The equation of a parabola that has a curvature 6 at the origin is [tex]f(x) = 3\cdot x^{2}[/tex].

An equation of a parabola that has curvature 6 at the origin is [tex]\rm f(x) = 3x^2[/tex].

We have to determine

An equation of a parabola that has curvature 6 at the origin.

The equation of a parabola that has a curvature a at the origin is;

[tex]\rm f(x) = ax^2[/tex]

The value of a is given by k(0) = 8;

[tex]\rm k(0) = 2a\\\\6 = 2a\\\\a = \dfrac{6}{2}\\\\a=3[/tex]

Therefore,

The equation of a parabola that has a curvature a at the origin is;

[tex]\rm f(x) = ax^2[/tex]

[tex]\rm f(x) = 3x^2[/tex]

Hence, an equation of a parabola that has curvature 6 at the origin is [tex]\rm f(x) = 3x^2[/tex].
