If two angles are both obtuse, the two angles are equal. What is the converse??

Answer:

T(3) = -23°C

Step-by-step explanation:

Constant Rate of Change

Given an initial condition of a variable T, To and a constant rate of change m, it's possible to write a model to predict the value of T in time t:

[tex]T(t)=T_o+mt[/tex]

The initial temperature the scientist measures of a chemical solution is To=-14.06°C.

It's known the temperature decreases at a constant rate of -2.9°C each hour, thus the model is:

[tex]T(t)=-14.06-2.9t[/tex]

Evaluating at t=3 hours:

[tex]T(3)=-14.06-2.9\cdot 3[/tex]

[tex]T(3)=-14.06-8.7[/tex]

T(3) = -22.76°C

Rounding to the nearest whole degree:

T(3) = -23°C

Answer:

B. Her model cannot be improved.

Step-by-step explanation:

We make this conclusion because it seems Isabella's model isn't actually proffering any solution to increase/reduce the number of strikes she has had.

Hence, any changes made do not clearly seem to improve the present model she is using.

Answer: 4.75

with u = 10, a = -2, t = 1/2

=> [tex]s=10.\frac{1}{2}+\frac{1}{2}. \frac{(-2).1}{4}=5-\frac{1}{4}=\frac{19}{4}=4.75[/tex]

Answer:

An explicit rule for the nth term of the sequence will be:

[tex]a_n=-4\cdot \:2^{n-1}[/tex]      

Thus, option (A) is true.

Step-by-step explanation:

Given the sequence

[tex]-4, -8, -16, -32, ...[/tex]

A geometric sequence has a constant ratio r and is defined by

[tex]a_n=a_0\cdot r^{n-1}[/tex]

Computing the ratios of all the adjacent terms

[tex]\frac{-8}{-4}=2,\:\quad \frac{-16}{-8}=2,\:\quad \frac{-32}{-16}=2[/tex]

As the ratio 'r' is the same.

so

[tex]r=2[/tex]

as

[tex]a_1=-4[/tex]

Hence, the nth term of the sequence will be:

[tex]a_n=a_0\cdot r^{n-1}[/tex]

substituting the values [tex]r=2[/tex] and [tex]a_1=-4[/tex]

[tex]a_n=-4\cdot \:2^{n-1}[/tex]      

Therefore, an explicit rule for the nth term of the sequence will be:

[tex]a_n=-4\cdot \:2^{n-1}[/tex]      

Thus, option (A) is true.

Given:

Total number of home runs = 583

Home runs hit by LA Dogerse = 6% of the total home runs

To find:

The number of home runs hit by LA Dogers.

Solution:

We have,

Home runs hit by LA Dogerse = 6% of the total home runs

                               [tex]=\dfrac{6}{100}\times 583[/tex]

                               [tex]=\dfrac{3498}{100}[/tex]

                               [tex]=34.98[/tex]

                               [tex]\approx 35[/tex]

Therefore, LA Dogerse hits about 35 home runs.

Actually Welcome to the Concept of the Straight lines.

Since there are more than one lines that can land plane safely, we take one of it,

When, X = 10 and Y = 7, so the equation we get as,

y-7 = m(x-10) + c

lets find slope, that is value of m,

y2-y1/x2-x1 = m

so, 9-7/ 7-10 = 2/-3

so, m= -2/3

so the final Equation is,

=> y-7 =(-2/3)(x-10) +c

Answer:

x=3

Step-by-step explanation:

The triangle has angles 30,60,90

In this type of right triangle, the ratio of the sides is 1:square root of 3:2

In this type of triangle, the square root of 3 is equal to the 1 in the ratio above because it is across from the angle 30

With this, we multiply the ratio at the top by the square root of 3

since x is across the angle 60, we multiply square root of 3 by the square root of 3 which equals 3.

I hope this makes sense

Answer:

Please check the explanation.

Step-by-step explanation:

As the given graph includes distance 'd' at the y-axis and time 't' at the x-axis.

so from the distance-time graph, it is clear that the graph includes 5 chunks.

The first chunk of the graph indicates that the object has started traveling. And the distance 'd' is being covered in time 't', as the slope is upward, hence the speed of the object is increasing.

The second chunk of the graph indicates the no distance is being covered. It means the object is at rest.

The third chunk of the graph indicates that the distance 'd' is being covered in time 't', as the slope is again upward, hence the speed of the object is increasing and the object has started traveling.

The fourth chunk of the graph indicates that the slope is downward, and the object has started traveling to get back to the destination, and eventually, the object has reached the starting point.

Answer:

4.8 minutes

Step-by-step explanation:

2.5/2.5=1

so

12/2.5=4.8

Answer:

4.8 minutes per mile

Step-by-step explanation:

Let mi be miles

Let min be minutes

2.5mi = 12min

Divide by side by the mile to get the unit rate

2.5/2.5 = 12/2.5

You will get 1 = 4.8

Answer:

A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}

Step-by-step explanation:

A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.

B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.

{ x : 0 ≤ x ≤ 6; x ∈ Z}

ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.

{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
