Answer:

3rd answer EF = 2√13

Step-by-step explanation:

Make a right triangle and use Pythagorean theorem a²+b² = c²

Go from point F 6 units down till point (1,-3) .From that point go 4 units left till you hit point E.

Triangle has legs a and b that are 6 and 4 units long so 6² + 4² = EF²

36 + 16 = 52

EF² = 52 find √52

EF = √52

There is no √52 as a whole number so rewrite 52 as a product of number who was a √ and the other who doesn't have a √

52 = 4 * 13

EF = √4 * √13 = 2√13

Palace help me solve these two equations 14, 15

14)

check the picture below... so.. is just a semi-circle and a rectangle, nothing fancy, get their area, sum them up.

15)

so... the voter turnout, is referring to, what's the percentage that voted, which year has the highest percentage... well, we simply check the percentage of the value provided from the total eligible voters, keeping in mind that, all eligible voters are the 100%

so.. for 1944

$\bf \begin{array}{ccllll}
amount&\%\\
------&----\\
86,607,000&100\\
47,976,670&x\\
\end{array}\implies \cfrac{86,607,000}{47,976,670}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 47,976,670}{86,607,000}\implies x\approx 55.39583405498$

for 1984

$\bf \begin{array}{ccllll}
amount&\%\\
-----&-----\\
167,727,000&100\\
92,659,000&x
\end{array}\implies \cfrac{167,727,000}{92,659,000}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 92,659,000}{167,727,000}\implies x\approx 55.2439380660239$

I inserted a picture of a question please state whether the answer is a b c or dI’ll insert a picture of question c and d

dangina [55]

The given function is:

$f(x)=x^2$

It is required to find the graph of g(x)=1/3 f(x).

Recall that the graph of a function g(x)=a f(x) is derived as a result of vertically shrinking the graph of f(x) towards the x-axis, where 0

Notice that in this case, a=1/3, which falls in the given interval for a vertical shrink.

Start with the graph of f(x)=x², which is the parent function for a quadratic function (graph in red):

Next, vertically shrink this graph towards the x-axis by a factor of 1/3 to graph, g(x)=1/3 f(x) in blue:

Notice that the graph that matches this from the options is the graph in option D.

The correct answer is option D.
