7) What will be the new position of the given point (9,-4) after reflection across
the line x = 1?
a) (7,4)
b) (7,-4)
c) (-7,-4)
d) (-7,4)

Step-by-step explanation:

Our equation;

[tex]-5=\frac{y-7}{9}[/tex]

Multiply each side by 9 to remove the fraction;

[tex]-45=y-7[/tex]

Add 7 to each side;

[tex]\boxed{-38=y}[/tex]

The length 2.3 and 7.8 units

We have given that ΔABC, c = 5. 4, a = 3. 3, and measure of angle A = 20 degrees.

The Law of Cosines, which tells us

[tex]a^{2}=b^{2} +c^{2} -2bccosA[/tex]

giving us a quadratic equation for b we can solve.  But let's do it with the Law of Sines as asked.

[tex]\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}[/tex]

We have c,a,A so the Law of Sines gives us sin C

[tex]sinC=\frac{csina}{a} =\frac{5.4sin20}{3.3} =0.5597[/tex]

There are two possible triangle angles with this sine, supplementary angles, one acute, one obtuse

[tex]C_{a}=arcsin(0.5597)=34.033^{0}[/tex]

[tex]C_{0}=180-C_{a} =145.96^0[/tex]

Both of these make a valid triangle with A=20°.   They give respective B's:

[tex]B_{a}=180-A-C_{a} =125.96^0[/tex]

[tex]B_{0}=180-C_{0} =14.033^0[/tex]

So we get two possibilities for b:

[tex]b=\frac{asinB}{sinA} \\\\b_{a} =\frac{3.3sin125.96}{sin 20} \\\\b_{a}=7.8\\\\ b_0=2.3[/tex]

2.3 units and 7.8 units

Therefore we get the length 2.3 and 7.8 units

Answer:

6and 7,8,9,10 CORRECT ME IF I'M WRONG

Answer: 30

Step-by-step explanation:

A sinusoidal equation can be used to describe the height because the height depends on a periodic motion, and the equation can be written as:

h(t) = 13ft*sin(pi*t) + 24ft

Remember that the sine function has a periodicity, such that:

sin(x + 2pi) = sin(x).

So, for a circle where if you do a complete rotation you end in the initial place, so there can be a relation between the height and a sinusoidal equation.

Notice that the initial position is 24ft above the ground, so we can write this, at the moment, as:

h(x) = Asin(n*t) + 24ft

A is the amplitude, it defines the maximum height and minimum height, both depend on the radius (the maximum height is 24ft plus the radius, the minimum height is 24ft minus the radius) then we write:

h(t) = 13ft*sin(kt) + 24ft

k depends on how much time takes to do a full rotation. We know that the sine function does a "complete cycle" in 2pi, while the wheel does a full rotation in 2 seconds, then we have that:

k*2 = 2pi

k = (2pi)/2s = pi

Then the sinusoidal equation that represents the height is:

h(t) = 13ft*sin(pi*t) + 24ft

Measurements are the metric units of an item, quantity or object

Beetles

The beetle covers two marks in a total length of 1 inch of 4 marks

So, the measurement of the beetle is:

[tex]Beetle = \frac{2\ inch}{4}[/tex]

Evaluate the quotient

[tex]Beetle = 0.5\ inch[/tex]

Ladybugs

The ladybug covers one mark in a total length of 1 inch of 4 marks

So, the measurement of the ladybug is:

[tex]Ladybug = \frac{1\ inch}{4}[/tex]

Evaluate the quotient

[tex]Ladybug = 0.25\ inch[/tex]

Butterfly

The butterfly covers four marks in a total length of 1 inch of 4 marks

So, the measurement of the butterfly is:

[tex]Butterfly= \frac{4\ inch}{4}[/tex]

Evaluate the quotient
