8 0

Answer:

-9,-8,-4, 5, 21, 46,95,159

Step-by-step explanation:

We keep adding the square numbers to the previous terms

-9+1^2=-8

-8+2^2=-4

-4+3^2=5

5+4^2=21

21+6^2=46

The next term is 46+7^2=95

The next one is 95+8^2=159

We got this by observing the pattern

What could be the next statement that Ivan makes his proof?
natali 33 [55]

Answer: Choice A) Triangle ABC is similar to triangle ACD by AA

AA stands for Angle Angle. Specifically it means we need 2 pairs of congruent angles between the two triangles in order to prove the triangles similar. Your book might write "AA similarity" instead of simply "AA".

For triangles ABC and ACD, we have the first pair of angles being A = A (angle A shows up twice each in the first slot). The second pair of congruent angles would be the right angles for triangle ABC and ACD, which are angles C and D respectively.

We can't use AAS because we don't know any information about the sides of the triangle.

Cot^2x/cscx-1=1+sinx/sinx
KATRIN_1 [288]
\bf \textit{difference of squares}
\\\\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)
\\\\\\
sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)\\\\
-------------------------------\\\\
\cfrac{cot^2(x)}{csc(x)-1}=\cfrac{1+sin(x)}{sin(x)}\impliedby \textit{let's do the left-hand-side}

\bf \cfrac{\quad \frac{cos^2(x)}{sin^2(x)}\quad }{\frac{1}{sin(x)}-1}\implies \cfrac{\quad \frac{cos^2(x)}{sin^2(x)}\quad }{\frac{1-sin(x)}{sin(x)}}\implies \cfrac{cos^2(x)}{sin^2(x)}\cdot \cfrac{sin(x)}{1-sin(x)}
\\\\\\
\cfrac{cos^2(x)}{sin(x)}\cdot \cfrac{1}{1-sin(x)}\implies \cfrac{cos^2(x)}{sin(x)[1-sin(x)]}

\bf \cfrac{1-sin^2(x)}{sin(x)[1-sin(x)]}\implies \cfrac{1^2-sin^2(x)}{sin(x)[1-sin(x)]}
\\\\\\
\cfrac{\underline{[1-sin(x)]}~[1+sin(x)]}{sin(x)\underline{[1-sin(x)]}}\implies \cfrac{1+sin(x)}{sin(x)}

From her window, Carmella looks up to the top of a neighboring building at an angle of 46°. Her
Vinil7 [7]

Answer:

270.3\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ADE

Find the value of h1

See the attached figure

h1=AD

tan(25\°)=\frac{h_1}{180}

Solve for h1

h_1=(180)tan(25\°)\\h_1=83.94\ ft

step 2

In the right triangle ABC

Find the value of h2

See the attached figure

h2=BC

tan(46\°)=\frac{h_2}{180}

Solve for h2

h_2=(180)tan(46\°)\\h_2=186.40\ ft

step 3

Find the height of the neighboring building

we know that

The height of the neighboring building is equal to

h=h_1+h_2

substitute the values

h=83.94+186.40=270.34\ ft

Round to the nearest tenth of a foot

h=270.3\ ft

1 Sales last year were $88,319. Percent of Increase 0.14. What<br> will it be next year?
Valentin [98]

Answer:

$100,683.66

Step-by-step explanation:

88319 = last years sales

.14 = percent increase

88319 * .14 = 12364.66

12364.66 + 88319 = 100,683.66

next years sales = $100,683.66
