Answer:

Step-by-step explanation:

I believe Brandon is incorrect. a > 12 means that you have to be older than 12 to use the gym but that is not true. You have to be at least 12 years old. This means you can be 12 and still go to the gym. You can represent this by using the expression a > 12.

Answer:

( 32/y ) - 6

Step-by-step explanation:

okay so quotient means the result obtained by dividing one quantity by another and the problem that follows that is 32 and a number, y

this is meaning that 32 and y and going to be dividing (32/y)

less than means subtraction and the number that's surrounding that is 6.

this means that 6 is going to be subtracted from (32/y)

hopefully this helped! good luck bud <3

Answer:

7.) 7

10.)  0

Step-by-step explanation:

When it means "evaluate the function", it's in essence asking us to see what the function spits out when we feed it a certain input. Our inputs are our x values, which spit out a y value.

Evaluating the function when x = 1:

Let's look at where the function has an x value of 1. We see it near the bottom of the table and see the y value associated with the input is 7. So when the function is fed 1 as an input, it spits out 7.

Evaluating the function when f(x) = - 2:

This one is a weird because of the new notation. Just think of it as some value of f, which we don't know (so we represent it as an x-variable) must equal -2. So let's look at our table to find out where our output is -2. We find that when f(x) = -2 the input is 0. So the input which gives -2 is 0.

Answer:

[tex] \frac { 5\sqrt{21} }{ - 7} [/tex]

Step-by-step explanation:

Firstly, let find some some other trig functions. We need to know all sides to know other trig functions. We know the horizontal side is -7 because it x-axis is at -7, it y-axis is at 24. so it vertical side is 24. Then we use the pythagorean theorem to find r

[tex] {7}^{2} + {24}^{2} = {r}^{2} [/tex]

49+576=

[tex] {c}^{2} [/tex]

525=c^2

[tex] \sqrt{525} = 5 \sqrt{21} [/tex]

So since we know that x= -7, y=24, r= 5 times sqr root of 21. We can find some trig functions. We can use function cosine here. Cosine equals

[tex] \frac{x}{r} [/tex]

cos=

[tex] \frac{ - 7}{5 \sqrt{21} } [/tex]

then we find secant which is the reciprocal of cos so we flip the numbers and that equals

[tex] \frac{5 \sqrt{21} }{ - 7} [/tex]

Answer:

Step-by-step explanation:

The first cat eats 1/15 of a bag per minute.

The second cat eats 1/10 of a bag per minute.

Together, they eat 1/15 + 1/10 = 1/6 of a bag in one minute.

Hence both can eat [tex]\frac{2x+3y}{30}[/tex]

when we form equations  out of given statements and then solve them to obtain answer are said word problems.

Given cat x can eat treat = 15 mints

cat x in 1 mint= x/15

given cat y can eat treat = 10 mints

cat y in 1 mint= y/10

hence both cats if eat together =[tex]\frac{x}{15} +\frac{y}{10}[/tex]

=[tex]\frac{2x+3y}{30}[/tex]

hence both can eat [tex]\frac{2x+3y}{30}[/tex].

Sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] is equal to [tex]\boldsymbol{\frac{26}{15}}[/tex].

A summation, also known as a sum, is the outcome of adding numbers or quantities arithmetically. A summation always has an even number of terms.

Summation is the adding of a series of numbers known as addends or summands; the result is their sum or total.

Sum of [tex]\frac{9}{10}[/tex] and [tex]\frac{5}{6}[/tex] [tex]=\frac{9}{10} +\frac{5}{6}[/tex]

                          [tex]=\frac{27+25}{30}\\\\ =\frac{52}{30}\\\\ =\frac{26}{15}[/tex]

Answer:

11.5

Step-by-step explanation: Since there is 1.15 land miles in one nautical mile you multiply 1.15 by 10 to find how many land miles are in 10 nautical miles.

The number of land miles there in 10 nautical miles will be 11.5.

Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.

If and only if the number being multiplied is more than one, multiplication produces a resultant number that is significantly larger than the original number.

As per the given,

One nautical mile = 1.15 land miles

In 10 nautical miles = 1.15 x 10 = 11.5 land miles

Hence "The number of land miles there in 10 nautical miles will be 11.5".

The line crosses the y-axis at y = 4. The coordinates of that point are (0, 4). This is the "start."

The line crosses a grid intersection again 2 units to the right and 3 units down at the point (2, 1).

The slope is the ratio of the vertical change to the horizontal change:

Answer:

12√2

7√3

Step-by-step explanation:

The length of the hypotenuse of a 45°-45°-90° triangle with a leg of 12 is 12√2 and the length of longer leg is 7√3 for 30°-60°-90° triangle.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Ratio of the sides of a 45°-45°-90° triangle is 1 : 1 : √2.

That is,

If sides opposite to 45° = x, then the side opposite to 90° = √2 x

That is, length of the hypotenuse = √2 x

Given length of a leg = 12

Length of the hypotenuse = √2 × 12 = 12√2.

Ratio of the length of sides of 30°-60°-90° triangle is 1 : √3 : 2.

That is,

Length of side opposite to 30° = x

Length of side opposite to 60° = √3 x

Length of side opposite to 90° = 2x  (Hypotenuse)

We have to find the longer leg, that is √3 x.

Length of hypotenuse = 14

2x = 14 ⇒ x = 7

Length of longer leg = 7√3

Hence the lengths are 12√2 and 7√3.

Answer:

1: 42

2: 107.6 °F

Step-by-step explanation:

For question 1 you insert the x and y values into the expression:

8 × 5 = 40 (xy = 40)

40 - 8 = 32 (xy - x = 32)

2 × 5 = 10 (2y = 10)

32 + 10 = 42 (xy - x + 2y = 42)

For question two you insert the celsius value into the expression:

9/5 × 42 = 75.6 (9/5C = 75.6)

75.6 + 32 = 107.6 (9/5C + 32 = 107.6)

The geometric series that converges is II. 0.3 + 0.12 + 0.048 + 0.0192 ( Option A).

To determine whether a geometric series converges, we need to check if the common ratio (r) of the series lies between -1 and 1 (inclusive). If the absolute value of r is less than 1, the series converges; otherwise, it diverges.

Let's check each series:

I. 2.9 - 3.19 + 3.509 - 3.8599

To find the common ratio, we divide each term by the previous term:

r = (-3.19) / 2.9 ≈ -1.1 (diverges)

II. 0.3 + 0.12 + 0.048 + 0.0192

To find the common ratio, we divide each term by the previous term:

r = 0.12 / 0.3 = 0.4 (converges)

III. 4 - 16 + 64 - 256

To find the common ratio, we divide each term by the previous term:

r = -16 / 4 = -4 (diverges)

So, the convergent geometric series is II. 0.3 + 0.12 + 0.048 + 0.0192.
