You have to break up the shape into different pieces in order to find the area.
(25•10)+(5•8/2)+(5•5/2)+(12•5)=342.5

The area is 342.5 ft^2

NEED ANSWERED ASAP WILL REWARD BRAINLIEST

Luda [366]

Answer:

The sum of the first 100 terms is 60400

Step-by-step explanation:

* Lets revise the arithmetic sequence

- There is a constant difference between each two consecutive

numbers

- Ex:

# 2 , 5 , 8 , 11 , ……………………….

# 5 , 10 , 15 , 20 , …………………………

# 12 , 10 , 8 , 6 , ……………………………

* General term (nth term) of an Arithmetic sequence:

- U1 = a , U2 = a + d , U3 = a + 2d , U4 = a + 3d , U5 = a + 4d

- Un = a + (n – 1)d, where a is the first term , d is the difference

between each two consecutive terms n is the position of the

number

- The sum of first n terms of an Arithmetic sequence is calculate from

Sn = n/2[a + l], where a is the first term and l is the last term

* Now lets solve the problem

- We will use method (1)

- From the table the terms of the sequence are:

10 , 22 , 34 , 46 , 58 , 82 , 94 , ............., where 10 is the first term

∵ an = a1 + (n - 1) d ⇒ explicit formula

∵ a1 = 10 and a2 = 22

∵ d = a2 - a1

∴ d = 22 - 10 = 12

- The 100th term means the term of n = 100

∴ a100 = 10 + (100 - 1) 12

∴ a100 = 10 + 99 × 12 = 10 + 1188 = 1198

∴ The 100th term is 1198

- Lets find the sum of the first 100 terms of the sequence

∵ Sn = n/2[a1 + an]

∵ n = 100 , a = 10 , a100 = 1198

∴ S100 = 100/2[10 + 1198] = 50[1208] = 60400

* The sum of the first 100 terms is 60400

Find the angle of XZY

qaws [65]

Answer:

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>

trigonometry i.g sin(x)=opp/hypo
PEMDAS

<h3>given:</h3>

opp:6
hypo:15

xyz angle

<h3>let's solve:</h3>

$let \: xyz \: angle \: be \: \alpha$

$according \: to \: the \: question$

$\sin( \alpha ) = \frac{xy}{zy}$

$\sin( \alpha ) = \frac{6}{15}$

$\alpha = asin( \frac{6}{15} )$

$\alpha = {23.6}^{o}$

therefore

<h3>xyz angle=23.6°</h3>

complete the square to rewrite y=x^2+8x+3 in vertex form and then identify the minimum y-value of the function

Zina [86]

The minimum y-value of the function for the parabolic equation is -13.

<h3>What is the vertex of a parabolic equation in quadratic form?</h3>

The vertex for an up-down facing parabola of the form y = ax² + bx + c is $\mathbf{x_v= -\dfrac{b}{2a}}$

From the given equation:

y = x² + 8x + 3

The parameters for the parabola are:

a = 1, b = 8, c = 3

$\mathbf{x_v= -\dfrac{8}{2\times 1}}$

$\mathbf{x_v= -4}$

If we replace the value of $\mathbf{x_v= -4}$ to find the minimum value of $\mathbf{y_v}$ value, we have:

$\mathbf{y_v = -13}$

Thus, the parabola vertex is (-4,-13). If a< 0, the vertex is a maximum value and If a>0, the vertex is a minimum value.
