Given:
In [tex]\Delta ABC, \overline{CA}=\overline{CB}[/tex].
[tex]\overline{CD}[/tex] is an altitude drawn from C to [tex]\overline{AB}[/tex].
To prove:
[tex]\overline{CD}[/tex] bisects [tex]\overline{AB}[/tex].
Proof:
In [tex]\Delta ABC[/tex], [tex]\overline{CD}[/tex] is an altitude drawn from C to [tex]\overline{AB}[/tex].
It means, [tex]\Delta ACD\text{ and }\Delta BCD[/tex] are right angle triangles.
In [tex]\Delta ACD\text{ and }\Delta BCD[/tex],
Hypotenuse : [tex]\overline{CA}=\overline{CB}[/tex] [Given]
Leg : [tex]\overline{CD}=\overline{CD}[/tex] [Common]
If the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then by HL postulate both triangles are congruent.
[tex]\Delta ACD\cong \Delta BCD[/tex] [HL postulate]
[tex]\overline{AD}\cong \overline{BD}[/tex] [CPCTC]
[tex]\overline{AD}=\overline{BD}[/tex]
It means, point D is the midpoint of [tex]\overline{AB}[/tex].
So, [tex]\overline{CD}[/tex] bisects [tex]\overline{AB}[/tex].
Hence proved.

The average rate of change of h(t) = -16t ² + 40t + 4 between t = 0 and t = 2 is
(h (2) - h (0)) / (2 - 0) = ((-16×2² + 40×2 + 4) - (-16×0² + 40×0 + 4)) / 2
… = ((-64 + 80 + 4) - 4) / 2
… = 16 / 2
… = 8
h(t) is measured in feet, so the average rate of change is measured in feet per second, so it's 8 feet per second.

is this table linear or exponential what us the slope and what is the equation ?
Answer:
this table is exponential
Step-by-step explanation:
the way we can tell this is because we can find a common ratio of 4. we know this because linear tables have a common difference exponential tables have a common ratio. i found this answer by dividing 32,768 and 8,192
32,768/8,192 = 4
you can find a linear function by subtracting point 1 and point 2.
write an expression that can be usedto find the nth termo of each sequence 9, 17, 25, 33
Answer:
The expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
[tex]a_n=8n+1[/tex]Step-by-step explanation:
Given the sequence
9, 17, 25, 33
a₁ = 9
Determining the common difference
d = 17-9 = 8
d = 25-17 = 8
d = 33-25 = 8
As the common difference between the adjacent terms is same and equal to
d = 8
Therefore, the given sequence is an Arithmetic sequence.
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 9, d = 8 in the equation
[tex]\:a_n=9+8n-8[/tex]
[tex]a_n=8n+1[/tex]
Therefore, the expression used to find the nth term of each sequence 9, 17, 25, 33 will be:
[tex]a_n=8n+1[/tex]There are 5 times as many boys as girls in a school.

Solve the following formula for the specified variable. B=1/4m(r+k) for r
Answer: r=4b/m-k
Step-by-step explanation: I think
The solution of the given formula B=1/4m(r + k) for r is r = 4(B/m) - k.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Given the expression,
B=1/4m(r+k)
4B = m(r + k)
r + k = 4B/m
r = 4(B/m) - k
Hence "The solution of the given formula B=1/4m(r + k) for r is r = 4(B/m) - k".

what is 43 7/8% of $2.35?
Round your answer to the nearest cent
Answer:
$1.03
Step-by-step explanation:
7/8 = 0.875
then
43 7/8 = 43.875%
43.875/100 = 0.43875
2.35 * 0,43875 = 1.031
Round to the neares cent:
1.03
Step-by-step explanation:
[tex]43 \frac{7}{8} \% \: of \: 2.35 \\ \frac{351}{8} \% \: of \: 2.35 \\ \frac{351}{8 \times 100} \times 2.35 \\ \frac{824.85}{800} = \boxed{\$1.0310625}[/tex]

Answer:
10% would be 6
Step-by-step explanation:
First you want to find the 100 percent amount to turn 40 into 100 you need to multiply it by 2.5 so you want to take 24 and multiply by 2.5 which equal 60 and 60 divided by 10 is 6
True or False. The higher the interest rate, the larger the balance will be after a determined amount of time (than with a lower interest rate).
Answer:
True
Step-by-step explanation:
Principle = Interest * Time

3/4 divided by 1/2
Step by step explanation
Answer:
1.5
Step-by-step explanation:
When we divide two fractions, such as 3/4 ÷ 1/2, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.
We also simplify the answers to fraction problems whenever possible.
Answer: 3/2 or 1 and 1/2
Step-by-step explanation: Remember that dividing by a fraction
is the same thing as multiplying by the reciprocal of the fraction.
The reciprocal of a fraction is just that fraction flipped.
So 3/4 ÷ 1/2 can be rewritten as 3/4 × 2/1.
Before multiplying however, notice that we
can cross-cancel the 2 and 4 to get 1 and 2.
Finally, multiplying across the numerators and
across the denominators, we have 3/2 or 1 and 1/2.
16 is a factor of 24.

Two submarines began dives in the same vertical position to meet at a designated point.
If one submarine was on a course approximated by the equation x + 4y = -14 and
the other was on a course approximated by the equation x + 3y = -8, at what location would they meet?
Answer:
(10, -6)
Step-by-step explanation:
The solution of the system of the equations given would be the location that they would both meet.
Let's solve:
x + 4y = -14 ----› Eqn. 1
x + 3y = -8 -----› Eqn. 2
Subtract Eqn. 2 from Eqn. 1
y = -6
Substitute y = -6 into Eqn. 1.
x + 4y = -14 ----› Eqn. 1
x + 4(-6) = -14
x - 24 = -14
x = -14 + 24 (addition property of equality)
x = 10.
The answer is: (10, -6)

Ramona went out with her 3 sisters, they spent $58 plus 9% tax on their meal. They also left 15% tip. If they divided up the bill evenly, how much did each of them spend?
Solution:[tex] \frac{58 + 58(9\% + 15\%)}{3} [/tex]
[tex] = \frac{58 + 58(0.09 + 0.15)}{3} [/tex]
[tex] = \frac{58 + 58 \times 0.24}{3} [/tex]
[tex] = \frac{58 + 13.92}{3} [/tex]
[tex] = \frac{71.92}{3} [/tex]
[tex] = 23.97[/tex]
Answer:Each of them did spend $23.97
