If you try
Tan 1 = GH/ HI then tan 42° = 11/HI= 0.90
After HI=11/0.90
The it equal to approximately 12.22

Answer:

HI ≈ 12.22

Step-by-step explanation:

tan I = GH / HI

tan 42° = 11 / HI = 0.90

HI = 11/0.90 = 12.22

Answer:

95.5°F

Step-by-step explanation:

Given the regression equation :

y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold

y = number of ice cream sold

x = temperature (°F)

The temperature when 95 iccream cones are sold will be ;

Here, y = 95

Using the model :

95 = 1.8x - 76.9

95 + 76.9 = 1.8x

171.9 = 1.8x

Divide both sides by 1.8

171.9 / 1.8 = x

95.5°F = x

Hence, temperature when 95 cones of ice-cream are sold is 95.5°F

$\triangle abc$ and $\triangle dbc$ share $bc$. $ab = 5\ \text{cm}$, $ac = 12\ \text{cm}$, $dc = 8\ \text{cm}$, and $bd = 20\ \t
Ratling [72]
What terms govern the length of this side?The basic rule of the triangle.First side length must be less than the sum of the other two sides.So to find X we must take the largest side of the triangles and compare them with amounts from other sides.

5+x>12
8+x>20    and it's system

x>7
x>12
general solution is x>12
<span>The least possible integral is 13.

PS: It's may be </span>yet 12, but in this case, triangle  BCD become segment.

I need to find the limit
Digiron [165]
For x=\dfrac{1}{2} the function is undefined.

\displaystyle&#10;\lim_{x\to\tfrac{1}{2}^-} x\sec (\pi x)=\infty\\&#10;\lim_{x\to\tfrac{1}{2}^+} x\sec (\pi x)=-\infty\\\\&#10;\lim_{x\to\tfrac{1}{2}^-}x\sec (\pi x)\not = \lim_{x\to\tfrac{1}{2}^+}x\sec (\pi x)&#10;
So, the limit doesn't exist.

1-6. Indicate whether each table or graph represents a proportional
Pie

Answer:

Step-by-step explanation:

Proportional relationship means,

x ∝ y

x = ky

\frac{x}{y}=k where 'k' is the proportionality constant.

From table (1),

\frac{1}{5}=\frac{2}{9}\neq  \text{Constant}

Therefore, relationship is not proportional.

From table (2),

\frac{1}{6}=\frac{3}{18}=\text{constant}

True.

So the relationship will be proportional.

From table (3),

\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}

Which is constant.

Therefore, relationship will be proportional.

From table (4),

\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103

Which is constant for every term.

Therefore, relationship will be proportional.
