Write the product (2x - 5)² in the form az²+bx+c and identify the values of a, b, and c. Type numerical values only. No variables
ANSWER FAST FOR LOTS OF POINTS
Answers
The product of (2x - 5)² can be written in the form az²+bx+c as follows:
(2x - 5)² = (2x)² - 2(2x)(5) + (5)²
= 4x² - 20x + 25
In this expression, a = 4, b = -20, and c = 25.

Find the perimeter of the object
Help step by step please!
Answers
Answer:
29.42 units
Step-by-step explanation:
1) Find the perimeter around the semi-circle
To do this, we find the circumference of the circle using the given diameter:
[tex]C=\pi d[/tex] where d is the diameter
Plug in 6 as the diameter
[tex]C=\pi (6)\\C=6\pi[/tex]
Divide the circumference by 2
[tex]\frac{6\pi }{2} \\= 3\pi[/tex]
Therefore, the perimeter around the semi-circle is 3π units.
2) Find the perimeter around the rest of the shape
Although it's impossible to determine the lengths of the varied sides on the right side of the shape, we know that all of those vertical sides facing the right add up to 6. We also know that all of those horizontal sides facing up add up to 7. Please refer to the attached images.
Therefore, we add the following:
7+6+7
= 20
Therefore, the perimeter around that area of the shape is 20 units.
3) Add the perimeter around the semi-circle and the perimeter around the rest of the shape
[tex]20+3\pi \\= 20+9.42\\= 29.42[/tex]
Therefore, the perimeter of the shape is approximately 29.42 units.

Mitch is making some bread dough. To make the bread dough, Mitch uses 5 1/2 cups of wheat flour, 1 3/4 cups of rice flour, and 2/3 cup of white flour. How many cups of flour, in total, does Mitch use? Show or explain all your work.
Answers
Answer: 7 11/12 cups of flour
Step-by-step explanation:
The number of cups of flour in total that Mitch uses will be gotten by adding the values for the cups for each type of flour that's used. This will be:
= 5 ½ + 1¾ + ⅔
= 5 6/12 + 1 9/12 + 8/12
= 6 23/12
= 6 + 1 11/12
= 7 11/12 cups of flour

Answer:
The percentage change each year is 2%
Step-by-step explanation:
Generally, we can have an exponential equation written as;
f(t) = I( 1 + r)^t
where f(t) is the value at a certain time
I is the initial value at t = 0
r is the growth rate
t is the time we are looking at
Thus, we have it that;
1.02 = 1 + r
r = 1.02 -1
r = 0.02
So, let us write 0.02 as a percentage
We have this as 2/100 which is the same as 2%
The percentage change each year is 2%

34.61Step-by-step explanation:
Find the diagram attached
From the diagram;
Hypotenuse = 81.9
Angle of elevation = 65degrees
Required
The value of x (Adjacent)
Using the SOH CAH TOA identity
cos theta = adjacent/Hypotenuse
cos 65 = x/81.9
x = 81.9cos65
x = 81.9(0.4226)
x = 34.61
Hence the value of x to the nearest hundredth is 34.61

if a triangle is dilated with a scale factor of 3, how do the sizes for the pre-image and image compare?
Answers
Answer:
Please check explanations
Step-by-step explanation:
When we dilate a particular figure, we are simply increasing the dimensions of its sides
By dilating the pre-image by a factor of 3, we are simply increasing the dimensions of it by a multiple of 3
so say for example, the base of the pre-image has a measure of 4 ft, the base of the image which is the pre-image dilated by a scale factor of 3 will be 4 ft * 3 = 12 ft
What this mean is that we have succeeded in tripling the dimension of the pre-image to give the dimension of the image
