Answer:
[tex] - 32[/tex]
Step-by-step explanation:
1) Simplify
[tex] \sqrt{32} \: to \: 4 \sqrt{2} [/tex]
[tex] - 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2} [/tex]
2) Use this formula: a/b × c/d = ac/bd.
[tex] - \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2} [/tex]
3) Simplify.
[tex] - \frac{32 \sqrt{2 \sqrt{2} } }{2} [/tex]
4)
[tex]simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4} [/tex]
5) Since 2 × 2 = 4, the square root of 4 is 2.
[tex] - \frac{32 \times 2}{2} [/tex]
6) Simplify 32 × 2 to 64.
[tex] - \frac{64}{2} [/tex]
7) Simplify 64/2 to 32.
[tex] - 32[/tex]
Therefor, the answer is option three -32

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted. Since then, it has grown approximately 0.5 centimeter per day.
a. Write a rule to describe the function.
b. After how many days will the zucchini plant be 0.195 meter tall?
A. h(d) = 12d + 0.5; 1.3 days
B. h(d) = [tex]\frac{d}{0.5}[/tex]+12; 4 days
C. h(d) = 0.5d; 39 days
D. h(d) = 0.5d +12; 15 days
Answer:
a) 12 + 0.5d d=day
b) 0.195/0.5=0.39d
Step-by-step explanation:
Answer
(a) Find out the a rule to describe the function.
To prove
Let us assume that the days be represted by d .
Let us assume that the height of plant be represted by y.
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
Than the function becomes
y = 12 + 0.5 × d
y = 12 + 0.5d
(b) Find out after how many days will the zucchini plant be 0.195 meter tall .
To prove
Let us assume that the days be represted by d .
As given
A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.
it has grown approximately 0.5 centimeter per day.
As
1meter = 100cm
0.195 meter convert into centimeter.
= 19.5cm
Than the equation becomes
12 + 0.5d = 19.5
0.5d = -12 + 19.5
0.5d = 7.5
d = 15 days
Therefore 15 days will the zucchini plant be 0.195 meter tall .

Helia invested 4000 AED for 3 years with a compound interest rate of 1.5%, Calculate the worth of her investment at the end of this time period. ( Show each step of your calculation)
Answer:
4180 AED
Step-by-step explanation:
Given data
Principal= 4000
Time= 3 years
Rate= 1.5%
The compound interest expression is given as
A= P(1+r)^t
substitute
A=4000(1+0.015)^3
A= 4000(1.015)^3
A= 4000*1.045
A= 4180
Hence the worth will be 4180 AED
the Pythagorean Theorem formula to find the missing side length. You must round your answer to the nearest tenth place (e.g. 10.8) 19 у 10
Answer:
I'm assuming we're solving for the hypotenuse, which is 21.5
Step-by-step explanation:
If a^2+b^2=c^2
Then 19^2+10^2 =461
This is c^2 so we must find the square root of 461
the square root of 461 is 21.47, or 21.5 rounded to the nearest tenth
what is area how do you find the area if a rectangle
Answer: To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Step-by-step explanation:
Answer:
If it is a rectangle you just do A=w*h
width times height
you don't have a picture showing the rectangle so I can't find the area

What are roots of (3x+7)(2x-5)=0
Answer:
x = - [tex]\frac{7}{3}[/tex] , x = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Given
(3x + 7)(2x - 5) = 0
Equate each factor to zero and solve for x
3x + 7 = 0 ( subtract 7 from both sides )
3x = - 7 ( divide both sides by 3 )
x = - [tex]\frac{7}{3}[/tex]
and
2x - 5 = 0 ( add 5 to both sides )
2x = 5 ( divide both sides by 2 )
x = [tex]\frac{5}{2}[/tex]

A 90° angle is divided into 2 angles.
Find the size of the angles.
3x + 40
4x - 6
Diagram not drawn accurately
Answer:
this angle's sum is 90°
(3x+40)°+(4x-6)=90°
7x+34=90°
7x=90-34
7x=56
x=56/7
x=8
3x+40 = 3×8+40 = 64°
4x-6 = 4×8-6 = 26°
please i need HELP x+y=15 , x-y=3
and
Answer:
x=9
y=6
Step-by-step explanation:
x+y=15 .............(i)
x-y=3...........(ii)
Subtracting equation (ii) from equation (i)
or, x+y -(x-y)=15-3
or, x+y-x+y=12
or, 2y=12
or, y=12/2
∴y=6
Now,
Putting the value of y on equation (i),
or, x+6=15
or, x=15-6
∴x=9

Slope intercept form of points 0, -4 and -1, 4
Answer:
[tex]y=\frac{0}{-1} -4[/tex]
Step-by-step explanation:
first, you have to find the slope, and to do that you use this equation [tex]\frac{y2-y1}{x2-x1}[/tex]
so, now to insert your points (0,-4), (-1,4)
(x1,y1) (x2,y2)
[tex]\frac{4-4}{-1-0} = \frac{0}{-1}[/tex]
now that you have the slope you can find the y-intercept of the slope-intercept form by looking at your first point (0,-4) and get -4
- if you were to look at this point on a graph it would be on the y-axis therefore, -4 is the y-intercept [if you don't have a point like this one then you can look at a graph with one of your points and make a slope until you are on the y-axis :)]
therefore, the slope-intercept form is y=[tex]\frac{0}{-1}[/tex] -4
[ps, your slope is a zero slope :)]
Answer:
y = - 8x - 4
Step-by-step explanation:
y = mx + b
"m" is slope, "b" is y-intercept.
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~~~~~
(0, - 4) are coordinates of y-intercept.
( - 1, 4)
m = [tex]\frac{4 + 4}{-1-0}[/tex] = - 8
y = - 8x - 4
Which equation illustrates the Associative Property of Multiplication?

Mr. Kramer's patio is in the shape of a trapezoid. The trapezoid and its dimensions are shown below. What is the area of the patio? A 144 square feet B 360 square feet C 315 square feet D 252 square feet
Answer:
C 315
Step-by-step explanation:
(12 + 30) * 15/2 = 315
The area of the trapezoidal patio is 252 ft².
What is a trapezoid?A trapezoid is a polygon that has only one pair of parallel sides. These parallel sides are also called parallel bases of trapezoid. The other two sides of trapezoids are non-parallel and called legs of trapezoids.
Given that, Mr. Kramer's patio is in the shape of a trapezoid, we need to find its area,
So, the area of the trapezoid is = sum of the parallel sides × height/2
= 12 + 30 × 12/2
= 42 × 6
= 252
Hence the area of the trapezoidal patio is 252 ft².

a coin is flipped and a six-sided die, numbered 1 to 6, is rolled. find the probability of flipping tails and rolling a number less than 3
Answer:
5/6
Step-by-step explanation:
There is a 1 out of 2 chance that you will roll tails, so the probability is 1/2.
A number less than three is a 2 and 1, so the probability is 2/6.
Add 1/2 + 2/6. (Change 1/2 to 3/6 so you can add.)
3/6 + 2/6 = 5/6
