Answer:
1 - 1/3 - 1/4 - 1/5
Step-by-step explanation:
Let's take it one step at a time.
Day 1 he completes 1/3 of the garage, so you subtract 1/3 from 1 which means he left 2/3
Day 2 he completed 1/4 more, so you again subtract, this time though 2/3 - 1/4, or in other words 1 - 1/3 - 1/4
So you do this one more time. 1 - 1/3 - 1/4 - 1/5
Can you handle this or do you need help with fraction subtraction.
F(x) = ax + b
Usa-se a informacao dada para criar um sistema de 2 equacoes com 2 variaveis. Resolve-se o sistema pare determinar os valores de a e b.Uma vez que se sabe os valores de a e b, escreve-se a funcao f com os valores de a e b. Finalmente calcucla-se f(3) usando a funcao f.
f(-1) = 3
a(-1) + b = 3
f(1) = -1
a(1) + b = -1
O sistema de equacoes e o seguinte.
Resolvemo-lo par adicao.
A variavel a e eliminada.
-a + b = 3
a + b = -1
2b = 2
b = 1
a + 1 = -1
a = -2
Agora sabemos the a = -2 e b = 1.
Escrevemos a funcao f usando os valores the a e b calculados..
f(x) = -2x + 1
f(3) = -2(3) + 1 = -6 + 1 = -5
f(3) = -5
Answer:
356.8cm3
Step-by-step explanation:
Volume of a cone= 1/3 * base area * height.
Note: don't be confused by right circular cone ; a cone is gotten from a cylinder by dividing it into three parts. One from the right vertex slanted to the middle of the base; another from the left vertex slanted to the middle of the base and the remaining portion with the surface base at the top.
Going forward; base area =pi * raduis * raduis [ area of a circle; the base is a circle]
Volume= 1/3 * (3.142 * 7.8 * 7.8 *5.6) = 356.83cm3
Volume= 356.8cm3 [ to the nearest tenth].
Tenth means 1/10= 0.1; that is value after the decimal point.
Answer:
B-The graph is incorrect. He should have shaded to the right of –8.
Step-by-step explanation:
We examine the steps Alfonso follows in graphing the inequality x > -8.
Step 1: Draw a number line, and place an open circle at –8.
A number line going from negative 13 to negative 3. An open circle is at negative 8.
The first step is correct, since we use an open circle for > or < and a closed circle for 
.
Step 2: Shade to the left of –8 to represent the infinite solutions to x greater-than negative 8.
This step is incorrect since <u>values to the left are always less than.</u>
He should have shaded to the right of -8.
<u>The error made is Option B. </u>
CHECK:
x=-7
-7>-8 (TRUE)
