What is the slope of a line that passes through (-4,-13) and (19,11)?

1 answer:

7 0

We can find the slope from the two given points using the standard formula:
$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$
$m=\frac{11-(-13)}{19-(-4)}$
$m=\frac{24}{23}$

aliina [53]

Answer:

3:4:7

Step-by-step explanation:

2/7 is apple juice

1/2 is orange juice

2/7 + 1/2=4/14+7/14=11/14

14/14 - 11/14=3/14

3/14 is cranberry juice

4/14 is apple juice

7/14 is orange juice

the ratio is 3/14 to 4/14 to 7/14

the ratio simplified is 3:4:7

What is the amplitude of the cosine function corresponding to the secant function graphed below ? a. -2 b. -1 c. 2 d. 3

Bas_tet [7]

Answer:

Step-by-step explanation:

From the graph, we obtain the trigonometric function as:

$y=2 \sec x+1$

The corresponding cosine function have equation.

$y=2\cos x+ 1$

This function is of the form: $y=a\cos bx+c$

where $|a|$ is the amplitude.

Therefore the amplitude is |2|=2

The third choice is correct

Find the difference between 7 1/2 and 2 3/4

NNADVOKAT [17]

Answer:

4 $\frac{3}{4}$ or 4.75

Step-by-step explanation:

first we're going to convert the number into improper fractions.

7 $\frac{1}{2}$ = $\frac{15}{2}$ and 2 $\frac{3}{4}$ = $\frac{11}{4}$

For subtracting it is suitable to adjust both fractions to an equal denominator, so we're going to multiply $\frac{15}{2}$ x2, it'll equal the same number.

So now we have $\frac{30}{4}$ - $\frac{11}{4}$ , 30-11= 19.

$\frac{19}4}$ simplified is, 4 $\frac{3}{4}$ .

As you can see I also added 4.75 as an answer, that's if the answer must be a decimal.

I hope this helps you!
