Which of the quadratic functions has the narrowest graph? y = –2x2 y=-1/2x^2 y = –4x2 y=1/7x^2

vovikov84 [41]

Look at the coefficient of x², ignore the positive or negative sign. The larger the coefficient, the narrower the graph.
in this case, the coefficients are -2, -1/2, -4, and 1/7
ignore the positive or negative sign, 4 is the largest number, so y=-4x² is the narrowest.

Note: the positive/negative sign tells you whether the graph opens upward or downward. It doesn't determine the width of the graph.

Melaine has written 5/6 of her essay. she has written 15 pages so far. How long does her entire essay have to be?

MrMuchimi

Answer:

18

Step-by-step explanation:

3*5=15

Therefore, every time she completed 3 pages that was a mark down.

3= 1/6 12=4/6

6=2/6 15=5/6

9=3/6 18=6/6 or 1 whole

A student solved for the radius of a circle with a circumference of 12π Step 1: C = 2 pi r. Step 2: 12 pi = 2 pi r. Step 3: Star

Greeley [361]

Answer:

The student made a mistake in step 4

The length of the radius should be 6 cm

Step-by-step explanation:

Let us write each step to find the radius of a circle from its circumference

Step 1:

∵ C = 2πr

∵ C = 12π

Step 2:

Equate 12π by 2πr

∴ 12π = 2πr

Step 3:

Divide both sides by 2π

∵ $\frac{12\pi }{2\pi }=\frac{2\pi r}{2\pi }$

Step 4:

∴ 6 = r

∴ The radius of the circle is 6 cm

The student mad a mistake he divided the left hand side by 2π and the right hand side by 2 only he left π with r

Step 4:

∴ 6 = πr

So he divided both sides again by π

Step 5:

∵ $\frac{6}{\pi }=\frac{\pi r}{\pi }$

Step 7:

∴ $\frac{6}{\pi }$ = r

The student made a mistake in step 4

The length of the radius should be 6 cm

The Answer to This Question

xenn [34]

Recall the Trigonometric Ratio below:

$\tt{ \large{sin \theta = \frac{opposite}{hypotenuse} } }\\ \tt{\large{cos \theta = \frac{adjacent}{hypotenuse} }} \\ \tt{ \large{tan \theta = \frac{opposite}{adjacent} }}$

For csc, sec and cot - they are reciprocal of sin,cos and tan.

$\tt{ \large{csc \theta = \frac{1}{sin \theta} } }\\ \tt{ \large{sec \theta = \frac{1}{cos \theta} }} \\ \tt{ \large{cot \theta = \frac{1}{tan \theta} }}$

What we know now is our hypotenuse, adjacent and opposite length.

hypotenuse = 15
opposite = 12
adjacent = 9

Therefore,

$\large{sin \theta = \frac{12}{15} \longrightarrow \frac{4}{5} } \\ \large{cos \theta = \frac{9}{15} \longrightarrow \frac{3}{5} } \\ \large{ tan \theta = \frac{12}{9} \longrightarrow \frac{4}{3} }$ As for the reciprocal of three trigonometric ratio. We just swap the numerator and denominator.

$\large{csc \theta = \frac{15}{12} \longrightarrow \frac{5}{4} } \\ \large{sec \theta = \frac{15}{9} \longrightarrow \frac{5}{3} } \\ \large{cot \theta = \frac{9}{12} \longrightarrow \frac{3}{4} }$

Answer

sin = 12/15 —> 4/5
cos = 9/15 —> 3/5
tan = 12/9 —> 4/3
csc = 15/12 —> 5/4
sec = 15/9 —> 5/3
cot = 9/12 —> 3/4

The first is non-simplifed form while the second that has the arrow pointing is the simplest form.

Let me know if you have any doubts.
