Answer: The acute angle ∠YXZ = 24.3°.

Step-by-step explanation:

If in triangle ABC, C is the angle included between sides a and b then

Area of triangle = [tex]\dfrac12a\cdot b\cdot sin C[/tex]

here, XZ = 21.5cm and XY = 13.5cm are sides that includes acute angle ∠YXZ..

Area of a triangle = 59.7cm²

then, as per given, we have

[tex]59.7=\dfrac12(21.5)(13.5)\ \sin X\\\\\Rightarrow\ 59.7=145.125\ \sin X\\\\\Rightarrow\ \sin X = \dfrac{59.7}{145.125}\\\\\Rightarrow\ \sin X =0.41137\\\\\Rightarrow\ X = \sin ^{-1}(0.41137)\approx24.3^{\circ}[/tex]

Hence, the acute angle ∠YXZ = 24.3°.

Answer:

Graph 1 or A

Step-by-step explanation:

The graph is gradually getting bigger as it starts at the left (0,-10) and gets bigger and bigger until it hits the end of the chart, increasing endlessly. That is exponential growth.

Answer:

52.2 weeks

Step-by-step explanation:

7000 - 475 = 6,525

6525 ÷ 125 = 52.2

Answer:

It will take her 53 weeks to get her goal of 7,000$

Step-by-step explanation:

I subtracted 475 from 7,000 to see how much she needed to save for. I got 6525. I multiplied 125 times 52 and got 6500. To get to her goal she needs 25 more dollars so, she'll have to work another week to get to that goal.

Answer:

y = -x - 7

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is x + y = 1.

First, let's put this into standard form.

x + y = 1

y = -x + 1

Now we have an equation in standard form. Its slope is -1. A line parallel to this one will also have a slope of -1.

Plug this value (-1) into your standard point-slope equation of y = mx + b.

y = -x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-7, 0). Plug in the x and y values into the x and y of the standard equation.

0 = -1(-7) + b

To find b, multiply the slope and the input of x (-7)

0 = 7 + b

Now, subtract 7 from both sides to isolate b.

-7 = b

Plug this into your standard equation.

y = -x - 7

This equation is parallel to your given equation (y = -x + 1) and contains point (-7, 0)

Hope this helps!

Answer:

-20x^2-4x

In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7.

75 I hope this helped and brainliest please!

Step-by-step explanation:

The equation for surface area for a square pyramid is A=a squared + 2a times the square root of (a squared over 4) + height squared. Since everything is 5 yd, the answer is 75.

Answer:

-8, -2 and 4

Step-by-step explanation:

Let the terms of the AP be a-d, a and a+d

If the sum is 6, then;

a-d+a+a+d = -6

3a = -6

a = -6/3

a = -2

Hence the first term is 6

If the product is 64

(a-d)(a)(a+d) = 64

-2(a²-d²) = 64

-2(4-d²) = 64

4-d² = -64/2

4-d² = -32

-d² = -32-4

-d² = -36

d² = 36

d = 6 or  -6

The first term is a-d = -2-6 = -8

second term is a  = -2

third term is a+d = -2+6 = 4

Hence the required AP is -8, -2 and 4

Answer:

There are 5 motorcycles and 8 cars in the parking lot.

Step-by-step explanation:

Set variables X to represent the number of cars and Y to represent the number of motorcycles. You will get the following equations:

X + Y = 13 (Total number of motorcycles and cars)

4X + 2Y = 42 (Total number of wheels)

Combine the two equations together and solve for Y and X

4(13 - Y) + 2Y = 42 note: X = 13 - Y

52 - 4Y + 2Y = 42

-2Y = -10

Y = 5

X + 5 = 13

X = 8

Answer:

  b)  -9.8t +18

Step-by-step explanation:

b) The instantaneous rate of change is the derivative of the height function. The power rule is separately applied to each term, and the results added.

  power rule: d/dx(x^n) = nx^(n-1)

Then the derivative is ...

  dh/dt = 2(-4.9t^1) +18(1 ·t^0)

  dh/dt = -9.8t +18

__

If you haven't been introduced to derivatives as such, then you find the instantaneous rate of change by finding the average rate of change over a vanishing interval.

  [tex]\dfrac{dh}{dt}=\displaystyle\lim\limits_{h\to 0}{ \dfrac{h(t+h)-h(t)}{h}}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{(-4.9(t+h)^2+18(t+h)+23)-(-4.9t^2+18t+23)}{h}\\\\\dfrac{dh}{dt}=\lim\limits_{h\to 0}\dfrac{-4.9(2th+h^2)+18h}{h}=\lim\limits_{h\to 0}{(-9.8t +18 -4.9h)}\\\\ \boxed{\dfrac{dh}{dt}=-9.8t +18}[/tex]
