Answer:
One thing that is unclear here is whether the "1." at the start is part of the number "1.2" or if it is an enumeration of the question, and the base raised to the exponent is in fact 2.
The rest of the equation seems to indicate the latter, so we'll solve both:
If 1.2ᵃ ₓ 2⁵ = 2⁰, then a is approximately equal to -19.009.
If as I'm guessing is the correct question, 2ᵃ ₓ 2⁵ = 2⁰, then a is equal to -5.
Step-by-step explanation:
Interpretation #1:
[tex]1.2^a \times 2^5 = 2^0\\1.2^a \times 32 = 1\\1.2^a = \frac{1}{32}\\log_{1.2} \frac{1}{32} = a\\a \approx -19.009[/tex]
Interpretation #2:
Here the question is much simpler, as we need only add the exponents when adding and dividing:
[tex]2^a \times 2^5 = 2^0\\2^a = 2^0 \div2^5\\2^a = 2^{-5}\\a = -5[/tex]

Kelvin finds a tile shaped like a triangle. He measures its angles to discover that it has two acute angles and one right angle. What type of triangle did Kelvin find obtuse triangle, acute triangle or right triangle?
Answer:
right triangle
Step-by-step explanation:
A Right triangle is a triangle that has one of its angle as 90°.
Since the triangular shaped tiles has a right angle, the kind of triangle Kevin found will be a right triangle.
A right triangle has two acute angles (angles less than 90°) and a right angle

Triangle ABC is similar to triangle DEF
Answer:
A my dude. good luck!!!!!
Answer:
A
Step-by-step explanation:
AC = 5
DF = 15
5 x 3 = 15
BC = 3
EF = 9
3 x 3 = 9
Do you see the pattern? So as you can see the difference between Triangle ABC and DEF is the multiply/divide 3 so if you want to find DE then you should set it up as:
[tex]\frac{4}{3}[/tex] = [tex]\frac{DE}{9}[/tex] and to check if its right if you solve it you get [tex]\frac{4}{3}[/tex] = [tex]\frac{12}{9}[/tex]
and as you see [tex]\frac{12}{9}[/tex] and [tex]\frac{4}{3}[/tex] are literally the same thing just you need to simplify [tex]\frac{12}{9}[/tex]

Katie and Sunnie both have 20-gallon fish tanks that are leaking water! After 15 minutes, Katie's tank has leaked 43 gallon. After 20 minutes, Sunnie's tank has leaked 34 gallon. Which tank is leaking faster?
Answer:
Katie's gallon
Step-by-step explanation:
Katie and Sunnie both have 20-gallon fish tanks that are leaking water!
For Katie
After 15 minutes, Katie's tank has leaked 4/3 gallon.
The rate of leakage =
4/3 gallon × 15 minutes
= 16
For sunny
After 20 minutes, Sunnie's tank has leaked 3/4 gallon.
Her rate is given as:
= 3/4 gallon × 20 minutes
= 15
Therefore,
The tank that is leaking faster is Katie's gallon
A property dealer charges a commission of 2% on the first 25000 and 1.5 % on the remainder. What commission does he charge for selling a plot of land of 130000
Answer:
$2075
Step-by-step explanation:
commission = 0.02 x $25,000 = $500
The remainder = $130,000 - $25,000 = $105,000
Commission on the remainder = 0.015 x $105,000 = $1,575
Total commission = $1,575 + $500 = $2075
* URGENT * Given f(x) = 6(2-x), what is the value of f(-8)?
open ended question
Answer:
f(-8) = 60Step-by-step explanation:
When we are given a function in this format, we substitute the x value in the equation. F(x) is simply another way of saying y.
if x = -8
6 (2 - -8)
6(10)
60
f(-8) = 60

I have a square with a side of 5.25 in. There is a circle inside this square that is big enough to touch all four sides. What is the area that is not inside the circle?
Answer:
5.9125in^2
Step-by-step explanation:
Step one:
Given data
Dimension of square= 5.25 in
Area of sqaure= 5.25^2= 27.5625 in^2
We are told that the sides of the circle touch the sides of the square
hence the diameter of the circle is 5.25in
radius= 5.25/2= 2.625 in
Area of circle= πr^2
Area of circle = 3.142*2.625^2
Area of circle=3.142*6.890625
Area of circle= 21.65 in^2
Step two:
The area that is not inside the circle
=Area of square-Area of circle
=27.5625- 21.65
=5.9125in^2
Determine the zeros of f(x) = 3x^2 – 10x – 8. (List them in
order from least to greatest, separated by commas. Enter any
fractions as a/b.)
Answer: The zeroes are -2/3 and 4
Step-by-step explanation: The factored form you get from this is (3x+2) and (x-4), set these equal to 0. x-4=0 and 3x+2=0.
The zeroes of the function in the order from least to greatest will be - 2/3 and 4.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The equation is given below.
f(x) = 3x² – 10x – 8
Then the zeroes of the function are given as,
f(x) = 0
3x² – 10x – 8 = 0
3x² – 12x + 2x – 8 = 0
3x(x – 4) + 2(x – 4) = 0
(x – 4)(3x + 2) = 0
x = 4, - 2/3
The zeroes of the function in the order from least to greatest will be - 2/3 and 4.

Landen's front lawn measures 20 feet by 80 feet. He counts to find that there are
120 blades of grass per square inch. How many blades of grass are in the entire
lawn?
Answer:
[tex]27,648,000[/tex]
Step-by-step explanation:
The area of a rectangle is given by [tex]l\cdot w[/tex]. Landen's 20 feet by 80 feet front lawn therefore has an area of [tex]20\cdot 80 = \fbox{$1600\: \mathrm{ft^2}$}[/tex].
He counts there are 120 blades of grass per square inch. There are [tex]12^2=144[/tex] square inches in one square foot.
Therefore, his lawn has an area of [tex]1600\: \mathrm{ft^2}\cdot \frac{144\:\mathrm{in^2}}{1\:\mathrm{ft^2}}=230,400\:\mathrm{in^2}[/tex].
Thus, there are [tex]230,400\:\mathrm{in^2}\cdot 120=\fbox{$27,648,000$}[/tex] blades of grass in the entire lawn.
Does (2, 3) make the equation y = x true?
Answer:
No.
Step-by-step explanation:
If you substitute x = 2 and y = 3 into the equation, you get 3 = 2 which is not true.
The slope formula can be used to find the slope, m, of a line with points (L1, y1) and (22, 42).
Y2 - Yi
22 - 21
m
Which is an equivalent equation?
O Y1 = -m (22 – x1) + y2
yı = -m (x2 – 21) – Y2
Oyı = m (22 – 21) + y2
Oyı = m (22 – 21) – Y2
Answer: [tex](y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)[/tex]
Step-by-step explanation:
Point slope form: [tex](y-b)=n(x-a)[/tex] , where n=slope , (a,b) is the point through which line passes.
If slope of the line = m and line passes through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] :-
[tex](y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)[/tex]
So, the equivalent equations are :
[tex](y-y_1)=m(x-x_1)\ or \ (y-y_2)=m(y-y_2)[/tex]

Write the equation of the function on the graph.
Answer:
[tex] \huge \boxed {y = |x| + 3}[/tex]
Step-by-step explanation:
Similar to Parabola, except this is Modulus Function.
[tex] \boxed {y = a |x - h| + k} \\ a \: = slope \\ h = move \: \: to \: \: x - axis \\ k = move \: \: to \: \: y - axis[/tex]
From the graph. The graph doesn't have any movement/transformation to x-axis, only y-axis. The graph only shifts up 3 units from y = |x|.
Both slopes are also 1 (from rise/run)
Hence, the answer is
[tex]y = |x| + 3[/tex]
