Answer:
Growth
Rate of growth is 77%
Initial amount is 22
Step-by-step explanation:
Generally, the exponential equation can be written as;
F(x) = I(1 + r)^n
where I is the initial value, r is the rate is percentage
From the question, we can see that the initial value is 22
Kindly recall that we can write 1.77 as 1+ 0.77
Now 0.77 is same as 77/100 which simply imply77%
Thus, we have 77% as the rate

Step-by-step explanation:
what is the value of k?
Answer: k = 10
Step-by-step explanation:
mLXYZ = 180 - 115 = 65° (angles in a straight line)
65 + (4k+5) + (6k+10) = 180
65+4k + 5 + 6k + 10 = 180
10k = 180 - 80
k = 100 / 10 = 10

Answer:
what i know for sure is 10/19 is rational
Answer:
=> All of the options are correct.
Step-by-step explanation:
a rational number is a number that can be shown as the quotient of two integers a and b(the denominator b must not be equal to zero).
10/19 => a = 10, b = 19 (correct)
85/74 => a = 85, b = 74 (correct)
-48 => a = -48, b = 1 (correct)
-57 =>a = -57, b = 1 (correct)
=> All of the options are correct.
Hope this helps!

Multiply 8/11 by the reciprocal of -16/121
Answer: -11/2
Step-by-step explanation:
First, find the reciprocal of -16/121. Which is -121/16 (you can put the negative sign anywhere). Now, you must multiply the two fractions:
[tex]\frac{8}{11} *-\frac{121}{16}[/tex]
You can cross out the terms 8 and 16 because they can be simplified into 1 and 2. And you can cross out 11 and -121 because they can be simplified into 1 and -11:
= [tex]\frac{1}{1} * -\frac{11}{2}[/tex]
Now multiply the numerators together, and multiply the denominators:
= [tex]-\frac{11}{2}[/tex]
solve the equation (X-1) (2x+5)=0
Answer:
x = -5/2
x = 1
Step-by-step explanation:
(x-1) (2x+5) = 0
Divide both sides by (x-1)
2x+5 = 0
Subtract 5 on both sides.
2x = -5
Divide 2 into both sides.
x = -5/2
(x-1) (2x+5) = 0
Divide both sides by (2x+5).
x - 1 = 0
Add 1 to both sides.
x = 1
Which graph shows the line y = 2x + 3?
Answer: Graph D
Step-by-step explanation:
The slope is 2
x goes after the slope in graph functions
The line goes through 3 on the y-axis so that’s where + 3 comes in.
2x + 3

pls hurry; 10 pts The first equation in the following system gives a company's income, in dollars, for selling x baseball caps. The second equation gives the cost of making x baseball caps. y = 8x y = -0.01 x2 + 4x + 3,200 The solution of the system is (400, 3,200). How would you interpret this solution?
Answer: The cost to make 400 baseball caps is $3,200
Step-by-step explanation:
The answer they gave you is a set of coords, x and y coords to be exact. That means that x value is inputed into the equation and that y value is the asnwer.
You put in 400, you get 3200.
They also gave us that x equals the number of baseball caps. Then y equals the cost of making those baseball caps
Answer:
The cost to produce 400 caps is the same as the income made from selling 400 caps.
The company will break even when it sells 400 caps; it will not make a profit.

What is the value of X in the given right triangle? WILL GIVE BRAINLIEST!
Answer:
Please mark me brainliest and I hope this helped!
x = 45
Step-by-step explanation:
In this case, we can use the Pythagorean Theorem to figure out the other side of the triangle.
c squared - a squared = b squared
10 squared - 7 squared = b squared
100 - 49 = b squared
51 = b squared
7.14 = b
Now that we know the other side is about 7, we can assume that x is equal to the angle between 10 and 7. So x equals 45.

Circumference of circles
Answer:
The circumference formula is 2πr and we know r = 1 so the answer is 2π.
Answer: 6.28 feet
Step-by-step explanation:
The formula for circumference is C= πd Diameter is radius times two. So use a value of π which is usually 3.14 or 3.1416 for practical purposes. Multiply by the diameter. 3.14×2=6.28.
Can someone answer this question thanks
Answer:
80 = x
Step-by-step explanation:
The base angles are the same if the side lengths are the same
The unmarked angle is 50 degrees
The sum of the angles is a triangle is 180 degrees
180= 50+50+x
180 = 100 +x
180 -100 = 100+x-100
80 = x
Answer:
80°
Step-by-step explanation:
In an isosceles triangle, if the two sides are the same length, then the two angles formed on the base line are equal.
The other angle on the base line is also equal to 50°.
Angles in a triangle add up to 180°.
x° + 50° + 50° = 180°
x° + 100° = 180°
x° = 180° - 100°
x° = 80°
What is the area of the composite figure? -70 cm2 -100 cm2 -105 cm2 -130 cm2
Make two shapes out of it.
The bottom is a rectangle 14 x 5 = 70 square cm
The top is a triangle 1/2 x 12 x 5 = 30 square cm
Total area = 70 + 30 = 100 square cm
Answer:
100 cm²
Step-by-step explanation:
The composite shape can be cut into two shapes. One triangle and one rectangle. The sum of their areas is the area of the whole composite shape.
The area of the triangle:
b × h × 1/2
(14 - 2) × 5 × 1/2
60 × 1/2
= 30 cm²
The area of the rectangle:
l × w
14 × 5
= 70 cm²
Add the areas of the two shapes.
30 cm² + 70 cm²
= 100 cm²
The area of the composite shape is 100 cm².

It’s just 22-24
Answer:
1) 5.9
2) 8.1
3) 54
Step-by-step explanation:
A is opposite, so we have sine 36=a/10
sine 36(10)=a
a=5.9
B is adjacent, so we have cosine 36=b/10
cosine 36(20)=b
b=8.1
Angles of a triangle add to 180
we have a angle of 36 and a right angle which is 90
36+90=126
180-126=54

simplify a radical expression below. √3/25
Answer:
D
Step-by-step explanation:
This can be broken up into √3 / √25, since √25 = 5 the final answer is √3/5.
Answer:
D. √3/5
hope it helps!
Step-by-step explanation:
√a/b is always written as √a/√b
So √(3/25)
= √3/√25
(√25 = 5 cuz 5*5=25)
= √3/5
So the answer is D.
